Sigma 100-400mm F5-6.3 DG DN OS (X-Mount) Review

Dustin Abbott

September 5th, 2023

For the second time in about a month, I am working on a review of a lens that was designed on full frame but is being ported over to the APS-C only Fuji X-mount.  Tamron determined that its full frame 150-500mm VC lens was compact and competent enough to work on Fuji (where there are few telephoto options).  The result is (for the most part) successful, as I detailed in my review here.  But Sigma also has an excellent candidate for this converter – a direct competitor to the Fujinon XF 100-400mm OS (my review here)in the form  Sigma 100-400mm F5-6.3 DG DN OS (we’ll call it the 100-400X in this review for brevity).  The 100-400X is going to be a bit of disruptor on X-mount for a couple of reasons.  The first is that it is a very competent lens in terms of performance.  The second is that is going to be a huge value alternative at $950 vs $1900 USD for the Fuji.  The 100-400mm zoom range is one of the most popular for those who want some serious reach for birding, wildlife, or sports but don’t want the larger size that comes with longer focal lengths.  When you consider Fuji’s 1.5x crop factor on X-mount cameras you get a focal length equivalence of 150-600mm on full frame, which is obviously incredibly useful, going from this at 100mm:

to this at 400mm:

I have the original Sigma 100-400mm DN a positive review on Sony E-mount in mid 2020.  It was the first of the third party telephoto lenses to come to Sony E-mount, and it was very welcome because it was along about a third of the price (though you had to buy the tripod collar separately if you wanted one) while providing most of the features and performance of the Sony 100-400mm G Master lens.  I suspect that it can serve a similar role here on Fuji, mostly because it can create images like this…

…for under a thousand bucks.  The fact that Fuji’s own 100-400mm is getting a little long in the tooth won’t hurt, either, though there are still a couple of areas where the Fuji has the advantage (compatibility with teleconverters, for example).  So, does using a lens designed for full frame on an APS-C only system make sense?  We’ll try to unpack that in this review.  If you prefer to watch your reviews, just click the video below.

Thanks to Gentec (Sigma’s Canadian Distributor) for sending me a pre-release review loaner of this lens. As always, this is a completely independent review. I’m doing this review on a 40MP Fujifilm X-H2 camera.

Sigma 100-400X Build and Handling

The Sigma 100-400mm is mostly similar in Fuji X-mount build to the Sony E-mount and Leica L-mounts before, though with a few minor feature changes due to the unique market positioning on Fuji. The lens continues to be lighter than the competition despite being designed for a larger sensor.  While the Fuji 100-400 OSS weighs in at 1375g (right over 48 oz), the 100-400X tips the scales at a relatively svelte 1135g (40 oz), a nearly 250g weight savings.  This is without the tripod collar, obviously (as this is an optional accessory for the Sigma), which will add another 123g.  (Nala really wanted to join this product photo session!)

The Fuji is 94.8mm in diameter and 210.5mm in length (3.73 x 8.29″), while the Sigma is thinner and shorter at 86 x 199.5mm (3.4 x 7.9″).  Not a major difference, obviously, but enough to be noticeable.  The front filter thread is also smaller at 67mm vs the 77mm standard for the Fuji.

Part of the reason for this difference is the fact that the Fuji lens does have an aperture advantage throughout the zoom range.  It starts at F4.5 and doesn’t hit F5 until a little before 200mm.  At 300mm, it’s f/5.2, and from 350mm on it is f/5.6.  The 100-400X performs much worse in this regard, as, while it starts at F5 at 100mm, it reaches F5.6 by 113mm where it remains until it hits F6.3 at 235mm.  What this means is that the Sigma is going to require more light (either slower shutter speed or higher ISO) than the Fuji in identical conditions regardless of the focal length.  

While the Sigma 100-400mm DN lenses are compatible with teleconverters on Leica L-mount, Fuji X-mount shooters are in the same boat as Sony E-mount – there are no TCs that can be used on the lens.

Sigma has made a few changes to the controls to accommodate the difference in Fuji’s protocols.  There are four switches and buttons on the side, but these have been slightly changed on X-mount.  Instead of an AF/MF switch, there is an AF-L/AF switch instead.  The Sony-style “Focus Hold” button has been rebranded as AF Function.  When AF-L is selected, you can use the button to either lock focus or reactivate autofocus afterwards.  So yes, we’ve got reduced function here compared to the Sony version.  The loss of a direct AF/MF switch is because Fuji lenses don’t come with this function (typically AF/MF is controlled from a dial on the camera).  The loss of more function on the “Focus Hold” button is due to the simple fact that unlike Sony or L-mount cameras, Fuji has no option to assign different values to this button in camera.

Other functions here include a 3 position focus limiter (FULL | 6M to infinity | Under 6M) and a three position switch for the OS (Mode 1 [Standard] | Mode 2 [Panning] | OFF).  

The OS (Optical Stabilizer) has gotten an updated tuning here and is now rated for 5 rather than 4 stops, which puts it on equal footing with the Fuji 100-400mm, which is also rated at 5 stops.  The first shot of Nala below was shot at 100mm and 1/7th of a second shutter speed, while the shot of the woodpecker is at 400mm and 1/20th of a second.

Both lenses have a standard zoom lock that locks the lens at 100mm and keeps it from extending.  The lens barrel will extend out a fair bit when zoomed to the telephoto end of the zoom range on both lenses, as these are externally zooming designs.

While these lenses have mostly similar controls, I prefer the layout and feel of the Sigma controls.  They are organized more logically and feel better to the touch.  I do have one practical complaint, however.  While hiking with the lens on a strap I would sometimes pull the lens up for a shot and it wouldn’t focus.  I would look, and the focus limiter would have moved to close focus position (furthest to the right), limiting focus.  I’ve not had this problem previously, so it does indicate in some carrying positions the switches can be inadvertently moved.

One feature the Fuji has that the Sigma does not is an aperture ring.  Aperture rings are fairly ubiquitous on Fuji lenses, but obviously this redesign by Sigma for X-mount didn’t extend quite that far.

Another minor difference is with the lens hood.  The Fuji lens features a little window in the hood to allow one to rotate a circular polarizer without reaching down into the hood.  The Sigma lacks this feature, though it does have a relatively small 67mm front filter thread and a nice flare in the lens hood at that point which allows one to reach in to rotate a C-PL fairly easily.  The lens hood also has a textured portion near the front for one to grasp as the 100-400 DN is designed to function as either a typical “twist” zoom or a “push-pull” design where one simply grasps the front of the lens hood and pushes or pulls the lens to the desired focal length.  Something for everyone here.

The 100-400 DN is a very nicely made lens, using a mixture of premium materials, including a brass lens mount, magnesium alloy in the first section of the lens, and then engineered plastics over a metal frame.  I didn’t get the feel that the Fuji lens was superior in materials.  The 100-400X is a good looking lens that feels very sturdy and well made.  It looks and feels more modern in design than the older Fuji option.

As noted already, the lens does not ship with a tripod collar (many people do not use one on a lens like this).  It comes with a rubber sleeve that covers the screws where the tripod collar attaches.  It has 100-400 stamped on there and makes for a cleaner finish when no tripod collar is attached.

The optional tripod collar is the TS-11. The tripod foot is nicely made, and, unlike the Sony tripod foot, it is ARCA compatible (meaning you can attach it right onto most tripods without the need for a quick release plate.  You can freely rotate and lock it in any position.

Using the tripod collar and foot makes a significant difference when using the lens on a tripod.  While the lens is on the lighter side of its class, it is still too heavy to easily balance on a tripod.

We have got a thick rubber gasket at the lens mount, but Sigma’s language does not specify other seal points in the lens itself, so that is likely another area where the Fuji lens is a little more robust.  Thus far Sigma’s “Contemporary” branded lenses (like this one) have only had sealing at the lens mount.

The 100-400 DN sports a useful magnification figure at 400mm of 1:4.1 (0.24x), which actually bests the Fuji’s 0.19x .  Minimum focus distance is 1.6m (5.25ft), which also best Fuji’s 1.75m.  Here’s what the Sigma’s MFD looks like:

You can really compress the background at close distances, and the bokeh is quite beautiful.  One could add an extension tube to allow for closer focus and higher magnification.  One thing is clear:  at minimum focus distance your backgrounds will completely blur out beautifully.  

The overall build quality is familiar to those who have used the lens elsewhere, but, for the most part, the 100-400X holds up pretty well when compared to the Fuji competition.

Sigma 100-400mm DN Autofocus Performance

This is an area that has historically been challenging for Fuji in general and even more so for third party lenses being adapted to the platform.  This is definitely the area where I experience my greatest frustrations with the 100-400x.  Sigma’s most recent telephoto lens on Sony received a new focus system (called HLA), but unfortunately we don’t get that here.  That means that we are working with an older STM motor that was in the original Sony design over 3 years ago.  There are moments when it works great, and other moments where it is pretty frustrating…and that’s on the X-H2, which has one of the most robust focus systems available on Fuji at the time of this review.  At times, autofocus was great, allowing me to effectively track and photography birds in rapid flight.

In other situations, just trying to focus on a slightly closer subject (but further than the minimum focus distance) would be impossible.  Focus would only go to the background, and even trying to choose a more obvious focus choice would not motivate focus movement.  Here’s what autofocus gave me in a shot that I wanted:

…and here’s what manual focus gave me.

I think we can all agree the latter is the much nicer shot.  The optics on this lens are really quite good, but there are definitely moments when the autofocus experience holds it back.  In the scenario above, there were a few minutes of trying to get autofocus to work, then another few minutes of trying to manually focus (a very slow process as it takes many full rotations to go through the focus possibilities ).  I estimate I had about six minutes invested in trying to get two very easy photos that should have taken a couple of seconds each.

Frustrating.

And these subjects weren’t going anywhere.  In another instance I had a great shot of a dragonfly about 10 feet away.  By the time I went through all the effort to get focus to the proper place, I got this:

You’ll notice there are no dragonflies on this pine bough.  The dragonfly patiently waited for a minute or so, but then moved on.

There were other situations where focus worked just fine.  About fifteen minutes after the dragonfly episode I got a nice series of well focused images of a butterfly flitting around wildflowers.

About five minutes later I saw a pileated woodpecker through the trees, and tried to react quickly to get the shot.  At first, this is all autofocus gave me.

It just refused to focus.  I maneuvered around a bit to allow eye detect to focus on the eye, and even with some foreground obstructions, I got a well focused result.

My observation has been that the current iteration of Fuji autofocus is that focus is quite good if the AI has a detectable subject to track, but it’s not nearly as good if there is no trackable subject and the core autofocus system (which hasn’t changed much in years) has to do the heavy lifting.  This shortcomings are magnified by a long focal range and a fairly slow maximum aperture of F6.3 on the long end.  I’m pretty spoiled by the autofocus capabilities of my long glass on either Sony or Canon, so I do find all of this somewhat frustrating.

In long tracking sequences with the X-H2 and the 100-400x, I found that tracking was okay if I started the burst with a focus lock.  There were some dips in and out, but probably about a 70% keeper rate.

If I started the burst without a good lock, the camera and lens never did achieve proper focus.  I could follow the action of the bird for dozens of frames without focus ever locking on, which is rather disappointing for 2023.  

Most of the time autofocus would grab the eye of the bird quickly, and I could get some great reactive shots.

Other times it just wouldn’t want to grab on at all.  I can’t really tell you why…because other times focus would lock well even with the subject’s back turned to me.

I shot long bursts at 15FPS with the mechanical shutter on the X-H2, and, while I got some shots during the session that I really liked, I also had a lot more castoffs than usual.  I would say that my overall keeper rate for the session was no better than 60%.

If you plan on doing a lot of BIF work or tracking a lot of fast paced action, you might want to spend a bit more for one of the Fuji options, though, to be fair, there isn’t really a “slam-dunk” option on the platform outside of the hugely expensive 200mm F2.  I think most able photographers will be able to get the Sigma 100-400X to work just fine, but just realize that you won’t be getting anything like a 90% hit rate for action work.  But I came away with dozens of great looking shots from just a 20 minute session of tracking gulls, so there is value here for birders or wildlife photographers.

On the video front I found that at 100mm (the easiest focal length to frame and typically fastest autofocus speed) focus pulls were reasonably successful, though with some obvious stepping.  Focus breathing was fairly minimal, however, so that’s a plus.  My “hand test” where I alternatively block the view of my face with my hand and then remove it went well, however, with good transitions from my eye to my hand.  In another clip, focus picked up my face quickly when I stepped into frame.

On a more negative side, I shot a clip of flowers in the morning sun and focus was initially good, but then focus racked forward to where nothing was in focus and didn’t return for at least five seconds.  

The footage itself looked good, with nice detail even when shooting at 8K on my X-H2.  I wouldn’t buy this lens for video work if that work required sophisticated autofocus, but if you want to augment your footage with some long shots, it certainly provides the least expensive way to get that kind of reach…and the footage looks great.

There is obviously room for improvement on the autofocus fronts.  I’m hoping that at least some of my complaints can be fixed via firmware updates, and perhaps the lens will also benefit from growth in Fuji’s autofocus systems in the future.  Some of these frustrations are Fuji frustrations in general, but there’s no question that I had fewer complaints when using Fuji’s own telephoto options and even the Tamron 150-500mm faired better in my tests.

Sigma 100-400 DN Image Quality

The Sigma 100-400 DN has a moderately complex optical formula with 22 elements in 16 groups.  This includes one FLD element (a low dispersion glass) and four SLD (special low dispersion element) to help with aberrations and distortion.  I was quite impressed with this lens on its native full frame when I reviewed it on a 42MP Sony a7RIII years ago, but the standard of Fuji’s 40MP APS-C sensor is much more demanding.  That many pixels on a smaller sensor is the equivalent of 90+MP on full frame, which requires a lens to be really strong optically to resolve the sensor.  Fortunately that is an area of strength for the 100-400x, as the optical performance is very competitive with the more expensive Fuji options.

This is a lens capable of producing really great looking results even on the high resolution Fuji sensor.

The Sigma gives a very strong showing when it comes to vignette and distortion.  What distortion is there is a very mild pincushion distortion that grows from a -1 to correct to a maximum of -3 to correct at 400mm (essentially 1,2,3), but at any point in the zoom range you could leave the distortion uncorrected and never even notice it.  Likewise vignette is at one stop or less throughout the zoom range, and you could easily leave it uncorrected as well.  You can see the uncorrected and then corrected results at 100, 200, and 400mm below.

You may have already figured out why these figures are so much lower here than what we saw on Sony – you are putting a full frame lens on a much smaller APS-C image circle, which means that the majority of the vignette and even distortion have been cropped off (they fall outside the APS-C image circle).  This is the area where a full frame lens is most advantaged by using it on a smaller sensor.  The Sigma does have full support of Fuji’s in-camera correction profiles for JPEG and Video as well, and RAW files will be corrected via the available correction profile in your favorite software.

I also saw minimal issues with Longitudinal Chromatic Aberrations (LoCA), which means that you should see little fringing in your shallow depth of field shots:

I also saw next to no Lateral CA near the edges of the frame.

All good thus far.  The harder test is coming, however, as the 100-400x must now face a much more pixel dense sensor than it was initially designed for.  The highest resolution E-mount or L-mount camera in 2020 was a 42MP full frame sensor; this pixel density is vastly higher.  That can be the area where full frame lenses on high resolution APS-C sensors can struggle. My resolution torture test is done on the 40MP Fujifilm X-H2 and results are examined at a very high 200% magnification.  Here’s a look at the test chart:

And here are the nearly 200% crops at 100mm, F5 from the center, mid-frame, and corners:

That’s an excellent result with very consistent sharpness across the image frame.  It also compares very favorably to the much more expensive Fuji XF 100-400mm, both in the center:

and in the corners:

The Sigma is the clear winner here, particularly in the corner, where it probably benefits from having the weakest performance from the lens cut off by the crop.

And yes, the Sigma has a slower aperture here (F5 vs F4.5), but if I stop both lenses down to F5.6 and compare at 100mm, the Sigma is still the clear winner all across the frame.  Impressive.

Stopping down to F5.6 or even F8 makes little improvement, if any, so you can be confident that you are getting close to peak performance wide open, which is really important on the 40MP Fuji bodies because diffraction arrives so early.  Real world results look good as well:

Diffraction arrives early on these bodies, so while the minimum aperture is F22, I would avoid using it because diffraction really robs away sharpness and contrast progressively after F8:

100mm is the high water mark for the lens performance, however, so while 200mm is good, it isn’t quite as good as what we’ve seen at 100mm (though very, very close):

Maximum aperture is F5.6 at 200mm, so stopping down to F8 brings no advantage because diffraction has started to very slightly soften the image.  Fortunately I think that most people will find real world results in and around 200mm at F5.6 very usable:

Image quality is weakest at 400mm, though it still exceeds what I saw from the older Fuji 100-400mm lens:

As before, the image quality is fairly consistent across the frame.  There’s good sharpness there to begin with, and the weakest part of the image gets cut off by the crop factor, leaving still strong corners.  When focus is nailed, you can get good results wide open at 400mm:

I don’t find contrast “off the charts”, but, to be fair, the only telephoto lens that I’ve been really impressed with on this high resolution sensor is the very expensive Fujinon XF 200mm F2 OIS (my review here).  I haven’t really seen better performance than this from any of the zoom competitors.  The Fuji 100-400mm has a slightly faster aperture of F5.6 at 400mm, but the more expensive XF 150-600mm is slightly slower (F7.1), and the Sigma results are as sharp as what I saw when testing that XF 150-600mm.  Bottom line is that this is about as good of image quality you are going to get at 400mm on the Fuji platform at the moment:

F6.3 isn’t incredibly fast (even at 400mm), but remember that the compression of the focal length is equivalent to 600mm on full frame, meaning that you can really defocus a background.  You can see from the image below that the quality of the bokeh doesn’t look like a $10,000 F4 prime (there is some nervousness to some of the textures), but also the background is strongly blurred.  At closer focus distances you can really defocus the background and get very creamy results with nice subject isolation:

Obviously I prefer the images with greater compression, as the creamy backgrounds look great.  But even in this image where the background is only mildly defocused, I still think the nature of the blur isn’t bad.

How about flare resistance?  I replicated the results from Sony here, as they are representative for the behavior on Fuji, too.  Flare is typically less of an issue with a lens like this, as the angle of view is so narrow (particularly on the long end), that you rarely point it at the sun.  Still, however, the results aren’t bad here.  There are six tests shown below.  The first series (of four) is of the lens at 100mm where the sun is most likely to be in the frame.  We’ve the sun centered in the frame wide open, then in the upper right corner, then with those results repeated at F11.  There’s a mild flare pattern that doesn’t worsen when the lens is stopped down.  Pretty good.

The final two images show the lens at 400mm with the lens wide open and then stopped down to F11.  There’s a little most veiling and loss of contrast here, though this will probably rarely be a real-world factor.

I ended my section on the autofocus with many reservations, but I’ve got no such reservations here.  The image quality stands up very well to the Fuji competition that will cost twice as much.  If you’d like to see more photo samples, I would recommend that you visit the image gallery here.

Conclusion

The 100-400mm focal range is popular for a reason.  By designing a variable aperture lens, lens makers are able to fit a fairly high performing long telephoto lens into a body roughly the size of a typical 70-200mm F2.8 zoom.  The end result is a a very flexible tool that can meet most anyone’s telephoto needs without breaking their backs in terms of the weight.  The Sigma 100-400mm F5-6.3 DG DN OS takes that to the next level, as it also won’t break the bank at a price point of right under $1000 USD.   

Fuji has been a bit of a wasteland for telephoto options, with only two lenses reaching beyond 300mm from Fuji.  The release of the Tamron 150-500mm VXD added a third lens, and this Sigma provides a welcome fourth option.  But the Tamron and Sigma lenses are actually full frame designs, but their reasonably compact size allows them to work on this smaller platform.  Like the Tamron, the biggest limitations include the lack of compatibility with teleconverters and the simple fact that autofocus isn’t as effective as what we’ve previously seen on Sony.

The difference in price between the Sigma and the Fuji options will probably mean that there are plenty of people who would be willing to do deal with a few more autofocus frustrations to get a quality telephoto lens that they can afford.  The fact that the Sigma 100-400X actually bests the Fuji competition optically won’t hurt, either.  The Sigma 100-400mm F5-6.3 DG DN OS is a perfect example of the role that Sigma can and should play in the Fuji marketplace – a quality mid-tier option that offers 90% of the first party lens at a much cheaper price.  

Pros:

  • Nice build quality including some weather sealing and premium materials
  • Slimmer and lighter than competing lenses
  • Fairly good tracking results for birding or fast action
  • Excellent image quality…particularly at the very important 400mm position
  • Nicer bokeh than many variable aperture zooms
  • Almost no vignette or distortion
  • Excellent chromatic aberration control
  • Improved optical stabilizer (5 vs 4 stops)
  • Good magnification and close focus results.
  • Fantastic price

Cons:

  • Autofocus can be frustrating at times
  • Tripod collar a separate purchase
  • Variable aperture zoom reaches smaller apertures very quickly
  • No TC options available on Fuji

Sigma 100-400mm F5-6.3 DG DN OS Fuji X-Mount Gallery

Dustin Abbott

September 5th, 2023

For the second time in about a month, I am working on a review of a lens that was designed on full frame but is being ported over to the APS-C only Fuji X-mount.  Tamron determined that its full frame 150-500mm VC lens was compact and competent enough to work on Fuji (where there are few telephoto options).  The result is (for the most part) successful, as I detailed in my review here.  But Sigma also has an excellent candidate for this converter – a direct competitor to the Fujinon XF 100-400mm OS (my review here)in the form  Sigma 100-400mm F5-6.3 DG DN OS (we’ll call it the 100-400X in this review for brevity).  The 100-400X is going to be a bit of disruptor on X-mount for a couple of reasons.  The first is that it is a very competent lens in terms of performance.  The second is that is going to be a huge value alternative at $950 vs $1900 USD for the Fuji.  The 100-400mm zoom range is one of the most popular for those who want some serious reach for birding, wildlife, or sports but don’t want the larger size that comes with longer focal lengths.  When you consider Fuji’s 1.5x crop factor on X-mount cameras you get a focal length equivalence of 150-600mm on full frame, which is obviously incredibly useful, going from this at 100mm:

to this at 400mm:

I have the original Sigma 100-400mm DN a positive review on Sony E-mount in mid 2020.  It was the first of the third party telephoto lenses to come to Sony E-mount, and it was very welcome because it was along about a third of the price (though you had to buy the tripod collar separately if you wanted one) while providing most of the features and performance of the Sony 100-400mm G Master lens.  I suspect that it can serve a similar role here on Fuji, mostly because it can create images like this…

…for under a thousand bucks.  The fact that Fuji’s own 100-400mm is getting a little long in the tooth won’t hurt, either, though there are still a couple of areas where the Fuji has the advantage (compatibility with teleconverters, for example).  So, does using a lens designed for full frame on an APS-C only system make sense?  You can get my thoughts either by watching my video review or reading the text review here.

Tamron 150-500mm F5-6.7 VC VXD (A057) Review

Dustin Abbott

June 8th, 2021

The Sony FE catalog of lenses is one of the most robust ever.  Sony’s bet on developing a more open source platform and welcoming third party development has really paid off, as at most focal lengths photographers have a plethora of choice.  The lone exception to this has been at longer telephoto lengths where both first party Sony options along with third party lenses have been rare.  I found Sony’s development of the FE 200-600mm F5-6.3 G OSS lens in 2019 very welcome because it gave Sony shooters the first long lens with a somewhat affordable price point.  I gave it very high marks in my review and eventually purchased one for myself.  That lens has largely gone unchallenged since its release, with only the Sigma 100-400mm F5-6.3 DN OS coming to market as an affordable alternative, though that lens was limited by being incompatible with extenders and thus topping out at 400mm of reach.  I found in my review that focus wasn’t quite up to Sony standards during tracking, either.  But now we have a more direct competitor, and with the “Tamron on Sony” advantage of having direct access to focus algorithms due to Sony having a financial stake in Tamron.  My experience has been that the Tamron lenses with RXD and VXD motors focus essentially as well on Sony as native Sony lenses.  That makes the Tamron 150-500mm F5-6.7 Di III VC VXD an interesting proposition, particularly when you consider that its price point of $1399 USD positions it about $600 cheaper than the Sony 200-600G.  The photos and tests that I share as a part of my review cycle of the A057 (Tamron’s code for this lens) have all been done with the new Sony Alpha 1 which will serve as my benchmark camera for the foreseeable future (my review here).

Tamron has taken a completely different approach to this design than what Sony did, electing to design as compactly as possible.  That makes this lens a MUCH easier lens to store and/or travel with, as you can see above.  They accomplished this by creating an externally zooming design and a smaller-than-typical maximum aperture on the long end of F6.7.  It used to be that pretty much all lenses conformed to a maximum aperture standard of F5.6, as this was considered the limit of what the focus systems in many DSLRs could handle.  Anything smaller and the focus system didn’t get enough light to effectively focus, and, in many cases, the focus system would just refuse to autofocus at all if a combination with a smaller maximum aperture was mounted on it (say an F5.6 lens along with a 1.4x TC, resulting in a maximum aperture of F8).  Tamron and Sigma did have some lenses with a maximum aperture of F6.3, but they accomplished that through a bit of electronic trickery that told the camera the maximum aperture was actually F5.6.  That limitation does not exist with many mirrorless cameras, though, and Canon has even produced a few RF telephotos lenses with a maximum aperture of F11.  The 150-500mm VXD is less extreme, and the maximum aperture at 500mm of F6.7 is two-thirds stop smaller than F5.6 but only one-third stop slower than the maximum aperture of F6.3 found on the Sony 200-600G.  The difference between the lenses is less pronounced when they are fully zoomed out as the Sony lens is internally zooming.

Like many recent Tamron lenses, the 150-500mm VXD has a very strong performance at minimum focus distance, with two different magnification levels at the wide and telephoto ends.  At 150mm you can achieve nearly a 1:3 ratio of magnification (0.322x), which is extremely useful:

Tamron recognized that this focal range is just too long to rely solely on the in-body-image-stabilization of Sony bodies, so this is the first of their full frame lenses for Sony FE that has Tamron’s VC (Vibration Compensation) optical stabilizing system.  The A057 also has their high speed, high torque VXD (Voice-coil eXtreme-torque Drive) linear motor focus system.  This is an impressive lens on paper, but what is the real life performance like?  Is this a serious alternative to the admittedly large but also excellent 200-600G?  That’s what I attempt to answer in either my text or video reviews.  You can read on to find out my conclusions, or click on the thumbnails below to watch the video review below.

Thanks to Tamron USA for getting me an early loaner of the lens.  As always, this is a completely independent review.

A057 Build and Handling

Tamron has a tried and true formula on Sony that they’ve largely stuck to until this point.  That has included weather sealing, no switches on the barrel, a standard 67mm front filter thread, no aperture ring or focus hold button, and a reliance on Sony’s IBIS (In-Body-Image Stabilization) to handle the optical stabilization.  The nature of the A057 means that the blueprint simply doesn’t apply here, and in many ways this lens looks more like the G2 lineup from the DSLR days.  We’ve got a tripod collar, four switches on the barrel plus a zoom lock, a clutch mechanism, VC (Vibration Compensation, or an optical stabilizer), an 82mm front filter thread, and a substantially larger lens than anything we’ve seen from Tamron on Sony before.  In fact, the weight of the 150-500mm VXD is only 110g lighter than the Tamron 150-600mm G2 lens despite having a smaller zoom range, a smaller maximum aperture, a smaller size (the 150-600 G2 was 108.4 x 260.2mm while the new lens is 93 x 209.6mm), and being made for mirrorless.  That tells me that the A057 has a robust build and some serious optical construction packed into that more compact body.  Here’s a look at basic specs and comparisons against some other alternatives.

On Sony, obviously, the physical comparisons to the DSLR lenses are not particularly relevant.  In fact, most relevant to the discussion will be two lenses, most likely.  The first is the smaller, lighter, and cheaper Sigma 100-400mm DN, while the latter is the bigger, heavier, and more expensive Sony 200-600mm OSS.  If you want to go as light as possible (and don’t need 500mm of reach), then the Sigma might be an attractive option, though its not quite in the class of the Tamron on a number of levels.  Those wanting more reach are going to more seriously consider the Sony 200-600 G as an alternative.  As we’ve seen in our introduction, however, Tamron has taken a very different approach to design relative to the Sony.  Let’s quickly break down a few design advantages for Tamron’s approach:

  • The retracted Tamron lens is about 41% shorter
  • The Tamron will fit in far more carry solutions, and might allow you to transport with the camera mounted and ready for use
  • The front filter thread is a much more common 82mm vs 95mm for the Sony
  • The Tamron switches are more definite and easier to use
  • The Tamron is 215g lighter
  • The Tamron has higher magnification figures and more versatile MFD distances
  • The Tamron tripod foot is Arca-swiss

A few Sony advantages:

  • The internally zooming design makes it easier to use in the field
  • Many photographers trust the weather sealing of internally zooming lenses more
  • The Sony has a focus hold button (x3)
  • The Sony can be used with teleconverters
  • The Sony has an additional 50mm in zoom range

There’s some give and take here, obviously.  I prefer the ergonomics of the Sony once I’m in the field, but I prefer the Tamron for storage in between and for getting there due to its externally zooming design.  As noted, the Tamron is very compact when the zoom is retracted.  It’s dimensions are only slightly larger than the Canon 100-400mm lens I had standing in for the Sony 100-400 GM (the two lenses are extremely similar in size).

The Sony is in a completely different class of size, obviously.  The differences become even more pronounced with the lens hood attached, as the A057 has a much more compact lens hood relative to the large, deep one found on the Sony.  The Tamron presents a substantial yet compact form when not zoomed out.

The lens extends nearly 8cm when zoomed to 500mm (about three inches), so that does cause the gap between the sizes of the lenses to close somewhat.

The zoom action is smooth with about 75° of rotation to achieve full zoom.  While this is a good performance, it can’t quite compare to the even smoother, quicker performance of the Sony’s internal zooming mechanism.

A lot of photographers have strong reservations about the sealing of any externally zooming lens.  I personally haven’t had issues with professional grade, well sealed externally zooming lenses, but neither do I live in an extremely dusty or moist climate.  Tamron has done a thorough job of weather sealing the lens, however, with seal points that begin at the lens mount and extend throughout the lens to a fluorine coating on the front element.  I see roughly 11 seal points as a part of the design.

Time will tell how effective the sealing is, but I haven’t heard anecdotal negative feedback from my audience over the sealing on other Tamron lenses for Sony.  If you live in a high impact environment and have concerns over sealing, you might want to consider the Sony 200-600 G instead, as it is basically the only lens in this class with an internally zooming design.

While Sigma has taken a lot of design cues from Sony for some recent lenses (aperture ring, focus hold button, declickable aperture), Tamron has stuck with their tried-and-true DLSR design.  There is no focus hold button, but there are some other innovative features.  There are four switches in a raised bank on the side of the lens, and I find the switches to have a more substantial, definite feel relative to those found on the Sony 200-600.  The first switch is a three position focus limiter that gives you the option to have the full range of focus available or to restrict either the distant focus (greater than the 3m) or close focus (15m and beyond).  Using a focus limiter can be even more important when using a lens with close focus abilities like this one, though autofocus is fast enough that I rarely resorted to the focus limiter.

The second switch is an AF/MF switch, followed by an ON/OFF for the VC.  The third switch gives you an option of three different modes for the Vibration Compensation system.  The first is the standard mode for general purpose, mode 2 is for panning, and mode three is called “Framing Priority” which seems to engage the stabilizer a little more actively in the viewfinder and would probably be the preferred mode for video.  The VC system seems to work smoothly, though it is basically impossible to determine if the system works in concert with the IBIS in your camera (if so equipped).  I saw pretty typical results from the VC, with a reasonably stabilized viewfinder image and fairly good results at low shutter speeds, though that’s not really the best use of these systems.  The first shot here is a 150mm shot taken handheld at 1/8th of a second, and the second is a 1/30 second handheld at 500mm.  

Neither is what I would call “tack-sharp”, but both are acceptably sharp even on a 50MP sensor.  More importantly is that I got reliable results with static subjects in moments when my shutter speed dipped to 1/100th or so.

One very cool new feature here is a clutch mechanism on the zoom ring that allows you to move the zoom ring forward and look the zoom position.  A white ring will show when the zoom position is locked.  This works really well in the field, allowing you to pretty much instantly either lock or unlock the zoom ring.  

What’s interesting is that the A057 also comes with a more traditional zoom lock as well, and, like usual, it only works at the 150mm position.  I see this more as something to use during transport or storage and the clutch mechanism as the preferred method to use in the field.

I also like the tripod collar design.  The actual function is pretty typical, with a locking knob that will allow you to rotate the collar 360° to your preferred position, and, if you continue to loosen it, the collar will come off altogether.  I like the fact that you can remove or attach the tripod collar with the lens attached to the camera and also that the lens has a finished area underneath where the tripod collar would sit when it is removed.  Some lenses have exposed screws or look unfinished with the collar removed. But what I really like here is that the tripod foot is Arca-swiss compatible, meaning that it can easily be mounted onto a tripod without the need for quick release plate.  The Sony’s foot is not Arca-compatible, and I have no idea why.

The lens hood is, as mentioned, fairly shallow for such a long focal length, but it seems to do the job and I’m certainly not complaining!  It does not have a locking mechanism, but does bayonet precisely and tightly into place.  It also has rubberized, reinforced front lip in recognition that often big lenses mounted on cameras will be set down facing downwards and also that things that stick further out in front of a photographer (like a long lens!) are more likely to get bumped on something!

One distinct advantage for the A057 over the Sony 200-600G is when it comes to versatility at minimum focus distance and maximum magnification.  The 200-600G is a fairy telephoto lens in this regard, with a constant MFD of just 2.4m (nearly 8 feet) and a maximum magnification figure of 0.20x, which is useful, for sure, but unexceptional compared to the Tamron.  Like many recent Tamron lenses, the A057 has a variable MFD with the ability to get closer on the wide end (just 0.6m [23.6 in] at 150mm) than on the telephoto end (1.8m [70.9 in] at 500mm).  This gives you an exceptional over 0.32x on the wide end and an also very useful 0.27x on the telephoto end.  You also get a lot more flexibility about your working distance with your subject, and the ability to do near-macro work.  Here’s what the Sony magnification looks like (1) vs the Tamron at 500mm (2) and then at its highest magnification level at 150mm (3).

In many ways this is one of the most useful variable-MFD lenses, as the working distance even at 150mm is still plenty and so you don’t feel you are right on top of your subject.  The A057 is capable of giving you a lot of lovely closeup shots at any point in the zoom range.

This is a definite strength for the lens and adds to its versatility.

The big appeal here is going to be the fact that Tamron has delivered a high quality lens that is going to fit in a lot of places where the Sony 200-600G simply won’t.  If you are traveling, for example, that could make all the difference in the world.  Different designs appeal to different consumers, and Tamron has delivered a different enough product at a different enough price point ($1400 vs $2000) that I think they will find a unique market.  I found the A057 easy to use in the field and easy to transport for a lens that reaches out to 500mm.

Tamron 150-500mm VC Autofocus

Tamron lenses have been fantastic in the autofocus department on Sony (though I’m less impressed with the lenses equipped with the OSD focus system, namely the 20mm, 24mm, and 35mm F2.8 OSD primes).  The lenses equipped with either their RXD or VXD linear motors have been fantastic, and the fact that Sony has a financial stake in Tamron has resulted in them having something more akin to first party treatment in terms of focus algorithms and even being able to get firmware updates in camera like first party lenses.  Tamron has utilized their high speed, high torque VXD (Voice-coil eXtreme-torque Drive) linear motor focus system in the A057.  This is the second lens (following the 70-180mm F2.8 VXD) to receive this particular focus system, so clearly it is a more robust focus motor in terms of torque than the RXD focus motors that they’ve utilized in slightly less demanding lenses.  It works very well here, delivering very fast, quiet, and accurate autofocus.

I had an opportunity to compare the A057 side-by-side with what I consider to be its most natural competitor – the Sony FE 200-600 F5.6-6.3 G OSS lens.  The Sony focuses amazingly well on Sony’s better cameras (I’ve used it on both A9 and Alpha 1 bodies along with the a7RIII).  For most work, you simply won’t notice a difference between the two lenses.  Both are very fast, very quiet, and very accurate.  We are in a bit of a golden age for focus, and both of these lenses are far beyond what we found on, say, the 150-600mm lenses from Tamron and Sigma that made this kind of zoom range popular on DSLRs.

The Tamron will deliver excellent results in the typical, non-challenging settings like mild action or still subjects…but I fully expected that.  What I wanted to know is if it could compete with the Sony for fast action and demanding tracking situations.  I found the Sigma 100-400mm DN to be fairly good for tracking, though at something like a 70% keeper rate while the Sony was something more like 97% in comparisons.  The Tamron is definitely better than the Sigma for tracking, though still a few percentage points below the Sony in absolute performance.  I would put it more at the 90% range.  That makes it more than good enough for most photographers in most situations, though there is a caveat if you are shooting with Sony’s action cameras that I’ll detail in a moment.

Once again I turned to my friends at Jengar Goldens) to supply subjects for my tests, and they brought four Golden Retrievers of varying ages to Black Bear Beach along the Ottawa River for me to put these lenses to the test.  The great news was that the Tamron proved a great partner for tracking action.  My first sequence was one I knew would be difficult, as I wanted the sparkle off the water in the background, but that meant having the light at the back of the dogs (making tracking more difficult).  I did notice a few swings where focus moved ahead of the subject, and, towards the very end where the dog was closest and the glare off the water was most intense, I lost focus again, but I had mostly very well focused resulted in what I would categorize as an extremely challenging situation. 

I had about an 87% keeper rate, with most of the misses being at the end of each run where the lighting conditions were just a little too challenging.  To put that in perspective, that was about 300 shots with 260 well focused results under very challenging conditions.  For comparison sake, I got about a 92% keeper rate with the Sony 200-600G in the same kind of sequence, though these results are not entirely scientific.  There are too many variables, as the dogs don’t always run the same path, or the same speed, etc…  

In other sequences I tracked action laterally, or with the sun frontlighting rather than backlighting the dogs, and my keeper rate rose much higher.  Out of about 400 other shots with the A057, I only had 10 that were poorly focused, and they were all from one sequence where a foreground object distracted focus. 

It’s worth noting that the dogs were running away from me and there was no eye to track.  Fortunately there was some stylistic quality to those shots, so they turned out not to be wasted anyway!

This is a lens that has plenty of speed for tracking accuracy, and, while it isn’t quite as good as the Sony 200-600G, it is probably about 93% as good.  It’s definitely a tier above the Sigma 100-400 DN, too.

But there was a burning question I had when Tamron released this lens due to something that has become increasingly obvious as Sony has enhanced its action cameras.  I had noted on the a9 and a9II that I didn’t really get the 20FPS top burst rate with third party lenses.  It was limited to somewhere around 15FPS.  On the a9 it wasn’t a huge deal, as 5FPS isn’t a deal breaker, and if you shoot on the a7, a7R, or a7C cameras, you wouldn’t even see a difference.  But my test body is now the Alpha 1, which sports a 30FPS upper limit.  With Sony lenses I can in fact achieve that 30FPS, but in my tests I have discovered that third party lenses are still capped at the 15FPS range.  I wondered if this Tamron would be different…but unfortunately it is not.  I achieved a maximum burst rate of 15FPS in my sequences with the A057 attached, but when I switched over to the 200-600G, I saw the full 30FPS unleashed.  

This is obviously an artificial limitation imposed by Sony to help advantage first party telephotos, and it will only affect you if you have the higher end action cameras, but if you happen to own an a9 or Alpha 1 series camera, this is information you probably need to know.

And before we end this section, we’ll have to raise another as well:  Sony has limited the use of teleconverters to its first party lenses.  500mm is already a lot of reach, obviously, but the idea of getting out to 700mm with a TC would be attractive to some photographers.  If you want the flexibility of using a TC, though, you’ll have to pony up for a Sony lens at this stage of the game.  This isn’t on Tamron, as they have delivered a lens with a fantastic focus system, but sometimes as a third party lens maker you have to deal with some barriers presented by the first parties. 

I’ll end with a general observation:  variable aperture lenses like this are not designed for low light work.  That maximum aperture of F6.7 means that in very low light conditions the focus system isn’t left with a lot to work with, as the physical aperture can only open so wide to let in light.  This lens (or any similar lens) will work best in decent lighting conditions, be they natural light or good stadium/arena lights.  You need to be aware of that if you are purchasing to shoot sports.  It also means that if you want to keep the shutter speed up high enough to stop action, you’ll probably be shooting at higher ISO values in an arena, for example.  The only alternative, unfortunately, is to buy one of the serious telephoto primes that have a larger maximum aperture and cost 8x as much.  Most of us will just make do!  

A057 Image Quality Breakdown

Engineering a high performing telephoto zoom that reaches out to 500mm is no small task.  Tamron really shook up this segment with the release of their original SP 150-600mm F5-6.3 VC, which, incidentally, was one of my first times to have a lens before the public release date and the ensuing traffic when I released my review literally broke my website.  That lens and the following G2 upgraded version have been major success stories for Tamron, and clearly they hope to catch lightning in a bottle again with the A057.  Expectations are higher in 2021, however, and the existing Sony 200-600G is very, very good optically.  Tamron has an optical design of 25 elements in 16 groups, with five of those elements being LD (Low Dispersion), another XLD (eXtra Low Disperation), and two of them being Hybrid Aspherical elements.  You can see the optical diagram along with the MTF charts for both lenses below:

The MTF charts suggest that the Tamron should be quite close to the Sony lens optically at both ends of the zoom range.  I went back and looked at the MTF charts from the original 150-600mm VC and found that the new lens shows improvement in both resolution and contrast throughout the zoom range.  The new 150-500mm has a reduced zoom range relative to the older lenses, but there’s no question that this remains an extremely useful telephoto zoom range:

There’s also no question that the A057 is capable of giving you lovely, richly detailed and colored images in a wide variety of settings:

I will give you one practical caveat about telephoto lenses in general.  Long range shots can sometimes be less than satisfying at a pixel level in some conditions for the simple reason that telephoto images are more likely to be affected by atmospheric conditions like pockets of rising warm air.  This “heat haze” or “heat shimmer” bends and distorts light waves.  You’ve seen extreme examples perhaps in a movie where you can see heat waves rising off hot asphalt on a desert road, for example, but even milder conditions can sometimes reduce contrast or apparent detail through smaller amounts of “atmospheric distortion”.  This has nothing to do with the quality of your lens and everything to do with the environmental conditions.   This kayaking shot at 400mm is an example of this:

But this 500mm shot in more welcoming conditions produced a much sharper, higher contrast image:

I share this to help those who might buy a relatively expensive lens and then get “freaked out” when sharpness in certain situations is less than expected.

Let’s turn to the technical side of things for a moment, however, and look at strengths and weaknesses from a clinical perspective.  We’ll start with vignette and distortion at 150mm.  There’s a mild amount of pincushion distortion and a minimal amount of vignette.  The distortion I corrected with a -5 and the vignette with a +27 and moving the midpoint to zero. 

Both of these are fairly negligible, and, while I do manual corrections to help measure the amounts of optical flaws, the reality is that most people will get automatic corrections either in camera (video and JPEGs) or through the inevitable correction profile for RAW images that will show up soon.

At 500m the amount of distortion and vignette is actually a tiny bit LESS, which is frankly quite surprising.  It isn’t unusual to see a fairly heavy amount of distortion and vignette on the telephoto end of zooms.

I used a -4 to correct distortion and a +22 to correct the vignette while moving the midpoint to zero for a nice, linear correction.  This is a very positive result when it comes to both of these factors, and I can’t see either vignette or distortion being any kind of issue for real world work.

I also didn’t see any issues with chromatic aberrations.  Even shooting a very high contrast subject like these irises backlit by sun produced no apparent CA.

Likewise in this high contrast shot of a dog running with both sand and water droplets in the air along with very bright highlights in the background, we see no evidence of any kind of color fringing.

These signs point towards a strong optical performance.  All of the tests and photos shown in this review are done on the 50MP Sony Alpha 1, which is Sony’s second-highest resolution full frame mirrorless camera at the time of this review.

If we start at 150mm, F5, we find that the lens produces stunningly good sharpness in the center of the frame and still very good performance in the corner.

If we compare the 150mm wide end of the A057 to the Sony 200-600g at 200mm, we find that the Tamron is about 99% as good in the center of the frame:

The Sony is a little more dominant in the corner, however, delivering a crisper, higher contrast result.

I found stopping the A057 down to F5.6 produced slightly better contrast at the 150mm mark, with a bigger lift at F8, where contrast and detail were noticeably better.

Performance at 200mm was better still, with less variance between the center and edge of the frame.  The 200mm corners rival what we just saw from the Sony.  In fact, if you stop the Tamron down to F5.6 (it still has a maximum aperture of F5 at 200mm), and do an apples to apples comparison, the Tamron actually wins:

That’s an excellent performance.

At 300mm the maximum aperture is now F5.6, but the excellent optical performance continues.  The lens remains extremely sharp in both the center and corner of the frame, with only a mild improvement available when stopping down to F8 thanks to excellent wide open performance.

By 400mm the maximum aperture is F6.3, but the wide open performance is just as good as we’ve been seeing.  I’ve grabbed the bill I’ve got at mid-frame on the left, and the right image is the top corner.  The mid-frame image is fantastically good while the corner image is still strong.

Some of the older supertelephoto zooms would really fade on the long end, but that’s just not the case with the A057.  At 500mm we’ve reached the smallest maximum aperture of F6.7, but we’ve retained an extremely strong center performance that nearly matches the exceptional performance of the Sony.

The same can’t be said for the corners, however, where the Sony is quite dominant.

All things being considered, however, that still makes the Tamron the second best lens I’ve ever seen in this class optically, which is seriously impressive.  No one would have dreamed ten years ago that we could have gotten this strong of an optical performance from a zoom lens reaching 500mm that cost less than $1500.  Kudos to Tamron for building a very strong optical performer.

There’s more to image quality than just sharpness, though.  What about the bokeh quality and the overall look of the images?  One serious advantage long telephotos have is that the nature of the focal lengths allow for very compressed backgrounds along with very shallow depths of field.  This often results in beautifully soft and creamy bokeh in a lot of situations, like this.

Here’s another example.

It’s hard for shorter focal lengths to imitate that degree of defocus irrespective of aperture.  In many, many situations the A057 gave me images that I really, really liked, with great color and lovely defocus.

Some shots had a less favorable ratio of subject to background, but I still thought those shots that landed in the transition zone looked pretty good.

Telephoto lenses like this tend to be less good at the typical “Christmas light” bokeh, but they are also rarely used for those types of shots.  The biggest complaint I could come up with from real world shooting was that in some of my shots of the dogs in action the highlights of the light sparkling on the water turned a little lemon shaped at the edges and with a little busyness visible in some of the bokeh highlights.

That’s about as much negative as I’m capable of coming up with, as by and large I think that images looked pretty great.

Flare resistance also proved to be quite good.  This lens has G2 (2nd Generation) B-BAR coatings, which are generally excellent.  It’s somewhat rare to end up with the sun in the frame when the angle of view is so small (particularly on the telephoto end!), but when I intentionally put it that, I saw very minimal impact from the sun either wide open or stopped down to F11.

In short, there really isn’t a lot to complain about optically here.  You can check out even more photos by visiting the lens image gallery here.  The A057 is improved from earlier Tamron supertelephoto zooms and is competitive with the Sony, which is the best lens of this type that I’ve tested.  Good stuff!

Conclusion

The Tamron 150-500mm F5-6.7 VC VXD is a very welcome addition to the Sony catalog of lenses.  It slots very neatly between the Sigma 100-400mm F5-6.3 OS DN and the Sony FE 200-600mm F5.6-6.3 G OSS lenses in terms of size, prize, and performance.  The Sigma is a good value lens, but it doesn’t have the reach of the other lenses and the autofocus is a bit behind the other two lenses.  The Sony is an exceptionally good lens, but it is larger, heavier, and more expensive than some photographers are willing to pay for.  The Tamron A057 gives a nice alternative to both, with a good size and price, good autofocus performance, and very nice image quality.

It did well in basically all areas of tested performance, though with a few unfortunate limitations imposed upon it by Sony.  These include an inability to use the lens with teleconverters and also a limitation on maximum burst rate on Sony’s higher end sports cameras like the a9 series and the Alpha 1.  For the moment, at least, you won’t get more than 15FPS on those cameras, though for many people that might just be enough.  It’s certainly enough to capture great action shots.

Perhaps the chief advantage for many potential buyers will the compact nature of the lens, which is a full 50mm shorter than the 150-600mm G2 lens from Tamron, and nearly 110mm shorter than the Sony 200-600.  That will allow owners of the A57 a lot more versatility in how they pack and transport the lens, which may just be the difference between the lens getting used instead of collecting dust on a shelf at home.  It is sometimes the practical considerations that are the most important.  And, at $1400 USD, the price point is within the range of far more photographers.  All of this adds up to the likelihood that Tamron has another hit on their hands in the form of the A057.

Pros:

  • The A057 is significantly smaller than the Sony 200-600G
  • Good quality of construction including robust weather sealing
  • Good function of design with generous controls
  • New zoom lock clutch design works well
  • VXD autofocus is quick, quiet, and accurate
  • Inclusion of VC means more stable results
  • Very low distortion and vignette
  • CA well controlled
  • Good sharpness across the zoom range
  • Great magnification and close up performance
  • Nice bokeh rendering
  • Well priced

Cons:

  • Cannot be used with teleconverters
  • Smaller maximum aperture than competitors
  • Lower burst rate on Sony’s top sports cameras compared to a Sony lens
  • No focus hold button

Tamron 150-500mm F5-6.7 VC VXD Image Gallery

Dustin Abbott

May 29th, 2021

The Sony FE catalog of lenses is one of the most robust ever.  Sony’s bet on developing a more open source platform and welcoming third party development has really paid off, as at most focal lengths photographers have a plethora of choice.  The lone exception to this has been at longer telephoto lengths where both first party Sony options along with third party lenses have been rare.  I found Sony’s development of the FE 200-600mm F5-6.3 G OSS lens in 2019 very welcome because it gave Sony shooters the first long lens with a somewhat affordable price point.  I gave it very high marks in my review and eventually purchased one for myself.  That lens has largely gone unchallenged since its release, with only the Sigma 100-400mm F5-6.3 DN OS coming to market as an affordable alternative, though that lens was limited by being incompatible with extenders and thus topping out at 400mm of reach.  I found in my review that focus wasn’t quite up to Sony standards during tracking, either.  But now we have a more direct competitor, and with the “Tamron on Sony” advantage of having direct access to focus algorithms due to Sony having a financial stake in Tamron.  My experience has been that the Tamron lenses with RXD and VXD motors focus essentially as well on Sony as native Sony lenses.  That makes the Tamron 150-500mm F5-6.7 Di III VC VXD an interesting proposition, particularly when you consider that its price point of $1399 USD positions it about $600 cheaper than the Sony 200-600G.  The photos and tests that I share as a part of my review cycle of the A057 (Tamron’s code for this lens) have all been done with the new Sony Alpha 1 which will serve as my benchmark camera for the foreseeable future (my review here).

Tamron has taken a completely different approach to this design than what Sony did, electing to design as compactly as possible.  That makes this lens a MUCH easier lens to store and/or travel with, as you can see above.  They accomplished this by creating an externally zooming design and a smaller-than-typical maximum aperture on the long end of F6.7.  It used to be that pretty much all lenses conformed to a maximum aperture standard of F5.6, as this was considered the limit of what the focus systems in many DSLRs could handle.  Anything smaller and the focus system didn’t get enough light to effectively focus, and, in many cases, the focus system would just refuse to autofocus at all if a combination with a smaller maximum aperture was mounted on it (say an F5.6 lens along with a 1.4x TC, resulting in a maximum aperture of F8).  Tamron and Sigma did have some lenses with a maximum aperture of F6.3, but they accomplished that through a bit of electronic trickery that told the camera the maximum aperture was actually F5.6.  That limitation does not exist with many mirrorless cameras, though, and Canon has even produced a few RF telephotos lenses with a maximum aperture of F11.  The 150-500mm VXD is less extreme, and the maximum aperture at 500mm of F6.7 is two-thirds stop smaller than F5.6 but only one-third stop slower than the maximum aperture of F6.3 found on the Sony 200-600G.  The difference between the lenses is less pronounced when they are fully zoomed out as the Sony lens is internally zooming.

Like many recent Tamron lenses, the 150-500mm VXD has a very strong performance at minimum focus distance, with two different magnification levels at the wide and telephoto ends.  At 150mm you can achieve nearly a 1:3 ratio of magnification (0.322x), which is extremely useful:

Tamron recognized that this focal range is just too long to rely solely on the in-body-image-stabilization of Sony bodies, so this is the first of their full frame lenses for Sony FE that has Tamron’s VC (Vibration Compensation) optical stabilizing system.  The A057 also has their high speed, high torque VXD (Voice-coil eXtreme-torque Drive) linear motor focus system.  This is an impressive lens on paper, but what is the real life performance like?  Is this a serious alternative to the admittedly large but also excellent 200-600G?  That’s what I attempt to answer in either my text or video reviews.  One thing is certain:  you can get beautiful photos with the Tamron 150-500mm VXD.  Enjoy the galleries below.

Sigma 100-400mm F5-6.3 DN OS Review

Dustin Abbott

June 18th, 2020

A lot of people will be very excited upon the announcement of this newest Sigma lens – the Sigma 100-400mm F5-6.3 DN OS for Sony FE (full frame mirrorless).  The 100-400mm zoom range is one of the most popular for those who want some serious reach for birding, wildlife, or sports, but who aren’t interested in the massive trade-offs that come with larger lenses like the Sony FE 200-600mm F5-6.3G OSS (my review here).   While the Sony FE 100-400mm G Master lens is an excellent lens (my review here), it is also very expensive and thus out of the range of many photographers.  The Sigma 100-400 DN (as we’ll call it for brevity) comes to market at nearly a third of the price (though you’ll have to buy the tripod collar separately if you want one) while providing most of the features and performance of the more expensive lens.

Several years ago (2017) I reviewed the Sigma 100-400mm F5-6.3 OS for Canon DSLR.  I gave the lens high marks for its optical performance while being less impressed with the speed of its focus and ability to effectively track action.  I also critiqued the fact that it wasn’t designed with a natural place to mount a tripod collar…something that many wildlife or birding photographers consider a must.  Fortunately Sigma has learned some lessons along the way, and the 100-400 DN builds on the strengths of the DSLR lens while vastly improving its weaknesses, leaving us with a very competitive lens that has plenty of speed for tracking action like birds in flight.

What’s equally important is that the Sigma has retained the beautiful image quality of the previous lens and is particularly strong at arguably the most important place in the focal range…400mm.

My hope is that this review will help you get a clear picture as to whether or not the Sigma 100-400 DN is the telephoto addition you’ve been looking for.  If you prefer to watch your reviews, I’ve got both a standard length and definitive (long format) video review available.  Just click the appropriate thumbnail below.

Thanks to Sigma Japan and Sigma Canada for providing me with a pre-production loaner of the lens for evaluation.  Their willingness to trust me with an early copy of the lens means that you get a thorough review right out of the box.  I’ve been assured that performance is representative of retail copy performance. I’ve reviewed the Sigma 100-400mm F5-6.3 DN OS on my Sony a7RIII and Sony a9 bodies.

Sigma 100-400 DN Build and Handling

Part of what makes a 100-400mm lens popular is that they tend to be relatively compact when compared to a 150-600mm or 200-600mm type lens.  It’s not usual for these type of lenses to weigh over 2kg, but the 100-400DN compares in at a relatively svelte 1135g (40oz), close to half that.  This is without the tripod collar, obviously, which will add another 123g.  The direct competitor here is the Sony 100-400 GM lens, and it weighs in at about 1400g.  Unlike the Sigma, however, only the tripod foot is removable on the Sony, so there’s definitively more potential to travel light with the 100-400 DN.  I didn’t have the Sony GM on hand to compare physically with, but I do own the Canon 100-400L II (a lens that is actually 12mm shorter than the Sony and equal in diameter), and you can get a sense of the physical differences here.

You can see that the Sigma looks more svelte, and that comes from being a bit shorter (197 vs 205mm on the Sony) and is slimmer in diameter (86 vs 94mm).  The other obvious physical difference is that the Sigma has a black finish while the Canon/Sony options are finished in a shade of white.  Some people don’t really care one way or the other, but I have heard that many prefer the black finish so as to draw less attention to their gear.

The 100-400 DN is a very nicely made lens, using a mixture of premium materials, including a brass lens mount, magnesium alloy in the first section of the lens, and then engineered plastics over a metal frame.  My impression was that while the lens isn’t quite as well made as the GM, it is definitely a cut above the more plasticky feel of the Sigma or Tamron 100-400mm lenses for DSLRs.  It’s a good looking lens that feels very sturdy and well made.

As noted already, the lens does not ship with a tripod collar (many people do not use one on a lens like this).  It comes with a rubber sleeve that covers the screws where the tripod collar attaches.  It has 100-400 stamped on there and makes for a cleaner finish when no tripod collar is attached.

The optional tripod collar is the TS-11, which was actually already on the market for the Sigma 105mm F1.4 ART as a replacement part (the 105mm ships with the collar included).  The upside here is that if you happen to own the 105mm you can actually share the collar between the two lenses.  The tripod foot is nicely made, and, unlike the Sony tripod foot, it is ARCA compatible (meaning you can attach it right onto most tripods without the need for a quick release plate.  You can freely rotate and lock it in any position.

Using the tripod collar and foot makes a significant difference when using the lens on a tripod.  While the lens is on the lighter side of its class, it is still too heavy to easy balance on a tripod.

The 100-400 DN does come with a full set of features.  There are four switches and buttons on the side, including an AF/MF switch, a 3 position focus limiter (FULL | 6M to Infinity | Minimum to 5M), a Focus Hold button that can be programmed with a variety of functions, and a three position switch for the OS (Mode 1 [Standard] | Mode 2 [Panning] | OFF).  The only difference from the GM lens is that the Sony has the focus hold button in three cardinal positions so that one falls easily to hand in different orientations.

Another difference is that the Sigma has a typical zoom lock switch which locks only at the 100mm position, while the Sony utilizes the tension ring like the Canon 100-400LII lens that can be used to lock the lens at any position.

Another minor difference is with the lens hood.  The GM lens features a little window in the hood to allow one to rotate a circular polarizer without reaching down into the hood.  The Sigma lacks this features, though it does have a relatively small 67mm front filter thread and a nice flare in the lens hood at that point which allows one to reach in to rotate a C-PL fairly easily.  The lens hood also has a textured portion near the front for one to grasp as the 100-400 DN is designed to function as either a typical “twist” zoom or a “push-pull” design where one simply grasps the front of the lens hood and pushes or pulls the lens to the desired focal length.  This is good news, as it will satisfy both crowds.

We have got a surprisingly thick rubber gasket at the lens mount; definitely more robust than the typical Sony offering.  Sigma’s language does not specify other seal points in the lens itself, so that is likely another area where the GM lens is a little more robust.

There’s another interesting observation at the rear of the lens, and that is that there is definitely room for a teleconverter to be mounted.

In fact, Sigma is in the process of releasing both a 1.4x (TC-1411) and 2.0x (TC-2011) teleconverter…but there’s a catch.  These are only being released for Leica L-mount at the moment, so there is no mention of a Sony counterpart.  While I don’t have a Sony 1.4x TC on hand, one of my contacts in the industry has promised to test this combination and I will update the review if it does in fact work.  At the least, I do think there is room for Sigma to release TCs for Sony, and I’m almost certain the lens will be compatible with TCs when they arrive.

The 100-400 DN sports a useful magnification figure at 400mm of 1:4.1 (0.24x), though this falls well short of the GM’s impressive 0.35x magnification.  Minimum focus distance is 1.6m (5.25ft).  Here’s what that looks like:

So, while this lens isn’t as effective as a “long range macro” as the GM lens, there’s an argument to be made in favor of the Sigma – it actually has better image quality at 400mm, which means that close-up performance is really quite good.  One could add an extension tube (and, potentially, a teleconverter) in the future to allow for closer focus and higher magnification.  One thing is clear:  at minimum focus distance your backgrounds will completely blur out beautifully.  Here’s some examples:

One area that Sigma has frequently been at the rear of the pack is when it comes to maximum aperture in their variable aperture zooms.  The lenses don’t hold the larger maximum apertures in the zoom range very long…and that remains true here.  I complained about the Sony GM lens in my review, “the Sony is already reaches its smallest maximum aperture of F5.6 very quickly.  The Sony goes from F4.5 to F5 by 115mm, and reaches the smallest maximum aperture of F5.6 by a paltry 162mm.  The Canon, by contrast, doesn’t hit F5.6 until 312mm!!”  The 100-400 DN is worse still, as, while it starts at F5 at 100mm, it reaches F5.6 by 113mm!  It fortunately holds F5.6 much longer and doesn’t hit the smallest maximum aperture of F6.3 until 235mm.  F6.3 is only one-third stop darker than F5.6, but either way lenses like these are a bit less useful in poor lighting conditions as you will really have to crank your ISO.  Getting faster maximum apertures at longer focal lengths often means spending a LOT more money and having a MUCH larger, heavier lens.  By the way, this follows the pattern established by the 2017 DSLR version of this lens almost exactly.

The lens barrel will extend out a fair bit when zoomed to the telephoto end of the zoom range…which is typical for such a lens.  You’ll note from my second photo why having a tripod collar is valuable when putting the lens on a tripod and zooming it out – there’s some sag even on my high end Robus RC-8860 tripod.

The 100-400 DN does come with Sigma’s OS (Optical Stabilizer), so it does not have to rely on Sony’s IBIS to stabilize the image.  The OS in the lens is rated at 4 stops of assistance, and it seems to be effective for stabilizing in either stills or video applications.  As always, it is worth pointing out that no stabilizing system stops the movement of subjects, so if you are photographing living things, it is always wise to keep your shutter speed up.  If you have a very still subject, however, it is possible to get well-stabilized images at lower shutter speeds. Here’s a real world shot at 1/40th second and 400mm (about 3 1/3rds stop of assistance):

Here’s another real world shot at 100mm and 1/10th second shutter speed (I see no signs of motion blur here).  

I show you real world results because these are actual instances while shooting in AV mode where the shutter speed dropped lower than what I would prefer and the stabilization saved the image.  That’s the true value of a stabilizer for stills.

There is a Mode 2 for panning, and, when tracking action, I work to keep the shutter speed up.  The stabilizer did its job by staying out the way on one axis and allowing me to smoothly track the action while providing me some stability at capture…helping me get this brilliant shot.

A closer look shows great detail and frozen action…just what we want with a lens like this.

Finally, Sigma has used their “Contemporary” designation with this lens like the DSLR version before it.  I’ve said and will continue to say that the term “Contemporary” is the most useless descriptor out there, as it is essentially meaningless.  Every new lens is “contemporary”, and there will come a point after time passes that none of these lenses are “contemporary”.  The word can also apply to design, but the design language is basically the exact same as “ART” and even “SPORT”.  What Sigma really means is “consumer grade” or “not premium”. but neither of those market very well.  In this case, however, the build and design of the lens is pretty much just right.  It’s reasonably compact and light while feeling fairly tough, handles nicely, and will present a tremendous value to many photographers on both Sony and Leica that want a reasonably priced, high performing telephoto lens.  It is perhaps the nicest made “C” lens that I’ve used from Sigma thus far.

Sigma 100-400mm DN Autofocus Performance

When I reviewed the DSLR version of this lens back in 2017, I drew this conclusion at the end of my examination of the autofocus performance, “Bottom line is that the combination of a relatively slow maximum aperture and an autofocus system that isn’t top shelf (at least in terms of speed) is perhaps the only place where the budget origins of this lens are betrayed and could be a limiting factor for someone who is serious about moving wildlife or sports.”  This was the area that I hoped most for improvement on this new lens, as Sigma’s autofocus motors on mirrorless have largely been very good.

Sigma has utilized a stepping motor on this lens for smooth, fast, and quiet operation.  The focus motor is extremely quiet and is only audible with your ear pressed against the barrel.  It is quiet enough that the on-board mic does not pick up any focus sounds during video focus or when doing focus pulls.  Good news there.

The focus motor is also nicely smooth when doing focus pulls.

Focus speed in AF-C mode is nice and fast, with typical focus changes being near instant.  One can get even better speed by utilizing the focus limiter where appropriate.  I was very pleased to be able to effectively track a robin taking off and in flight against a fairly busy background and even when some foreground objects interfered with the flight path.

When I tested the original Sigma 100-400mm, I was disappointed in its tracking abilities on either my Canon 5D Mark IV or 80D cameras.  I tried to follow the path of a dog chasing a ball and running towards the camera and had very low success even though my Canon 100-400L II was able to perform the same task in the same conditions with near perfect results.  I was delighted to see much better results when pairing the new 100-400 DN with my Sony a9 camera.  

First of all, let’s comment on framerate with the Sigma attached.  I got around 15 FPS on my a9, which is about average for my real world results.  In theory one can get up to 20 FPS on the a9, but the fastest I’ve actually seen even with a Sony lens attached is 17FPS, so I’m not really seeing a significant real world difference.  More important to me is that I got nearly 15FPS in the way I actually want to use my a9 – shooting both uncompressed RAWs and Very Fine JPEGs.

Secondly, I want to offer a few caveats about the real world shooting environment for my tracking tests.  The nature of tracking tests is that they aren’t strictly scientific, as there are a lot of uncontrolled variables in real world conditions.  In this case, the biggest difference is that I tested the Sony 100-400 GM and 200-600G in winter conditions with the dogs running through snow.  The reflection of light from underneath (snow) more evenly illuminates their faces, and the fact that in this case the dogs were running through water and swimming at times means that their fur was wet and darker, resulting in less contrast between their fur and eyes for the tracking system to detect.  In my opinion this makes the environment a little more challenging than when I tested the Sony lenses, so I do want to keep that in mind.  I want to thank JenGar Goldens for bringing me out with some of their beautiful dogs to track the action.

Despite these factors, however, I was generally pleased with the tracking ability of the 100-400 DN even if I didn’t feel like rate of perfectly focused results wasn’t quite as high.  In one burst of around 40 images tracking high speed action heading mostly right towards the camera, I had about 28-30 perfectly focused results, 5-7 acceptably focused results (the line between these two groups can be a little hazy), and five that weren’t well focused.  The latter group were typically due to a few “swings” where the focus either backfocused or front focused for one reason or another.  The upside is that through my many series (you can see these bursts in the video reviews) the focus would always correct back in the series rather than getting stuck out of focus somewhere.  This sequence was fairly representative of what I saw overall.

I suspect the Sony lenses would have had a few more keepers in this scenario despite the conditions, but at the same time there’s no question that the Sigma 100-400 DN is far more competitive this time around.  It was capable of getting me many well focused action shots.

If you are doing professional, critical work, you might want to spring for the GM lens, but I think that most photographers will be very pleased with the focus speed and precision of the 100-400 DN and will be very happy with the results they get from it.

There’s also the reality that your performance will depend on the quality of your camera body…and that $1500 difference between the two lenses could go towards a camera upgrade!

Sigma has also shown in times past that they will work to continue to refine autofocus performance via firmware upgrade (which in the case of Sony will come by running updates through the camera body like you would with a Sony lens), so there’s a possibility that we might see even better performance down the road.  There’s plenty of focus speed on tap, so I think the ingredients are there for even better results.  Overall, however, I’m pleased with the autofocus performance.  It supports all the various Sony focus modes, including Eye AF for people and animals.  This is great progress!

Sigma 100-400 DN Image Quality

The Sigma 100-400 DN has a moderately complex optical formula with 22 elements in 16 groups.  This includes one FLD element (a low dispersion glass) and four SLD (special low dispersion element) to help with aberrations and distortion.  But what kind of performance do those fancy elements give us?  

A pretty nice one, as it turns out.

The Sigma follows a familiar pattern for vignette and distortion for a telephoto zoom.  The distortion is all of the pincushion variety, and both it and the vignette steadily increase (though in moderate amounts) throughout the zoom range.  Both the distortion and vignette is strongest at 400mm, as you see below (corrected/uncorrected results at 100mm, 200mm, and 400mm shown).

In all cases the distortion and vignette presents in a linear fashion that isn’t difficult to correct.  At the extreme (400mm) the distortion pattern required a -6 value to correct and the vignette was a +51 with the midpoint slid all the way to the left.  The Sigma does have full support of Sony’s in camera correction profiles for JPEG and Video, and I suspect a correction profile for RAW files will soon be available in your favorite editing software soon.  Nothing ugly or unexpected here, though the Sony GM definitely wins on both these counts.

Chromatic aberrations are well controlled, and you can see from my LoCA test that there is little evidence of green and purple fringing and that contrast is good.

This proved true with real world results as well, where I saw little evidence of any kind of fringing in my various shots.

So let’s take a look at the resolution results.

*A note on testing:  testing lenses with longer focal lengths is a challenge, as it is best to run them indoors where you can control the lighting, but you need a LOT of room to run them.  I plan to make up a second smaller test chart that will help with this for the future.  In the meantime, however, my two sets of results from the Sony GM lens and the newer Sigma lens are not in identical lighting conditions.  Fortunately this has minimal impact on the actual results and we can still draw some quality conclusions. 

First of all, it is worth noting that when compared to the Canon 100-400L II, there’s a pretty significant difference in framing due to the fact that the Canon suffers from focus breathing that causes it to behave like less than its stated focal length at close distances.

The GM doesn’t breathe like that, so I suspect it and the Sigma will frame similarly at equal distances.

At 100mm the Canon and the Sigma are very close, with a mild advantage in the center and midframe going to the Canon and a slightly stronger advantage in the corners.

When compared to the GM, the general observations are about the same.  The Sony has a small advantage across most of the frame and is probably the best of the three in the corner.

Stopping the 100-400 DN down to F5.6 makes little difference, and there is only a mild difference at F8.  The Sigma is the least sharp at 100mm of the three, but not by a wide margin.  It is competitive there.

At 200mm the Canon continues with a mild edge everywhere but midframe, where the Sigma is about equal.  The competition with the Sony GM is closer, however, and I would be hard pressed to call a winner between the two lenses across the frame.  I’ll let you judge for yourself.

Stopping down to F6.3 and F8 produces some mild improvements in contrast and resolution, so there’s more room for improvement at 200mm when stopping down than what was available at 100mm.

Moving on to 300mm we see an interesting trend starting to emerge.  First of all, the Canon continues to be the most consistent lens of the bench (it remains the benchmark in this focal range optically), but the position of the Sigma vs the GM lens starts to reverse.  Many of the more inexpensive telephoto lenses start to fade at the long end of their range, but the Sigma is actually optimized to deliver stronger performance towards the latter portion of the range.  Even against the Canon (shown on the right), the difference midrame and corners is close, and the Sigma is a bit stronger than the GM.

At 400mm something amazing happens.  The Sigma shows a very strong performance here that rivals and even bests the more expensive options.  Let’s start with the Sony.  There’s a slight advantage for Sigma in the middle of the frame, a strong advantage mid-frame, and a win for Sony in the corners.

Compared to the Canon the Sigma has the advantage in the center of the frame while the Canon has a slight win in the mid-frame and edge.

This is a strong performance from the Sigma when you consider that it costs less than half as much as these two rivals.  In real world use, the differences between the GM and the Sigma are going to be minimal, with some give and take across the zoom range.  The 100-400 DN will give you a lot of images that you will love.

When coming out of the woods from a hike, I heard some mouthy crows losing their minds at each other.  I could barely make them out up in the tree, but I was pretty impressed by how crisp my result was when I took the photo.  This is 400mm F6.3:

Here’s another taken at 300mm, F6.3:

I don’t think image quality should be a limiting principle for any potential buyer.  If you want better image quality at 400mm, you probably need to invest in a very expensive prime lens.

I’ve also been fairly impressed with the bokeh quality.  None of these zooms can compete with the best prime lenses for the quality of their blur, but I’ve yet to see an image where the bokeh looked distasteful to me.  Here’s a sampling of different focus distances.

Obviously I prefer the images with greater compression, as the creamy backgrounds look great.  But even in this image where the background is only mildly defocused, I still think the nature of the blur isn’t bad.

How about flare resistance?  As I’ve often noted, it is typically less of an issue with a lens like this, as the angle of view is so narrow (particularly on the long end), that you rarely point it at the sun.  Still, however, the results aren’t bad here.  There are six tests shown below.  The first series (of four) is of the lens at 100mm where the sun is most likely to be in the frame.  We’ve the sun centered in the frame wide open, then in the upper right corner, then with those results repeated at F11.  There’s a mild flare pattern that doesn’t worsen when the lens is stopped down.  Pretty good.

The final two images show the lens at 400mm with the lens wide open and then stopped down to F11.  There’s a little most veiling and loss of contrast here, though this will probably rarely be a real-world factor.

As I noted previously, the strength of the Sigma 100-400mm has always been its optical performance relative to its price, and I feel like Sigma has improved the performance at the long end of the zoom range and managed to make a truly competitive lens that gets better as you zoom it out.  If you’d like to see more photo samples, I would recommend that you visit the image gallery here.

Conclusion

The 100-400mm focal range is popular for a reason.  By designing a variable aperture lens, lens makers are able to fit a fairly high performing long telephoto lens into a body roughly the size of a typical 70-200mm F2.8 zoom.  The end result is a marvelously flexible tool, with the ability to serve as everything from a long distance landscape option…

…to a long range “macro” option…

…to, of course, an excellent tool for capturing wildlife and sports in reasonable lighting.

Useful indeed, though often the price tag (typically north of $2000 USD) makes such a purchase an intimidating one for many photographers.  And that’s what makes a lens like the Sigma 100-400mm F5-6.3 DN OS Contemporary lens so important to a camera system.  It makes that versatility and performance accessible to the average photographer that doesn’t have deep pockets or who does photography for pleasure rather than profit.  Sigma has managed to take what was good about the original 100-400 Contemporary and improve on nearly all its weaknesses, and the end result is a well-rounded third party alternative to the much more expensive G Master lens.  I’ve heard many of you complain about the lack of a lens like the 100-400 DN on Sony.  You can now leap for joy like this golden, because the lens you’ve been looking for is  here!

Pros:

  • Nice build quality including some weather sealing and premium materials
  • Slimmer and lighter than competing lenses
  • Designed with a tripod collar in mind this time!
  • Autofocus system is quiet, fast, and accurate
  • Good tracking results for birding or fast action
  • Excellent image quality…particularly at the very important 400mm position
  • Nicer bokeh than many variable aperture zooms
  • Excellent chromatic aberration control
  • Effective image stabilizer
  • Good magnification and close focus results.
  • Fantastic price

Cons:

  • Tripod collar a separate purchase
  • Variable aperture zoom reaches smaller apertures very quickly
  • No TC options available on Sony at present (only on Leica)

Sigma 100-400mm F5-6.3 DN OS Image Gallery

Dustin Abbott

June 18th, 2020

A lot of people will be very excited upon the announcement of this newest Sigma lens – the Sigma 100-400mm F5-6.3 DN OS for Sony FE (full frame mirrorless).  While the Sony FE 100-400mm G Master lens is an excellent lens (my review here), it is also very expensive and thus out of the range of many photographers.  The Sigma comes to market at nearly a third of the price (though you’ll have to buy the tripod collar separately if you want one) while providing most of the features and performance of the more expensive lens. My review will help determine whether or not the Sigma is enough for your needs…and mabe  I’ll be reviewing the Sigma 100-400mm F5-6.3 DN OS on my Sony a7RIII and Sony a9 bodies, and you can see photos from both cameras below.  Stay tuned for my ongoing coverage.

Sigma 100-400mm f/5-6.3 Contemporary Review

Dustin Abbott

June 30th, 2017

First impressions matter. My first two impressions when opening the box and pulling out Sigma’s newest lens – the 100-400mm f/5-6.3 DG OS HSM Contemporary – were 1) the lens was smaller than I anticipated (not a lot bigger than a lens like Canon’s new 70-300 IS II and similar in profile) and 2) the build quality felt more premium than I anticipated. Both of these are good news for Sigma. On the negative side I also observed that this was the first Sigma lens that I’ve personally unboxed that did not have an included lens case. All in all, however, the positive first impressions for the 100-400 C easily outweighed the negative. I had fairly low expectations for this lens, in part because the lenses in this focal length have always carried a much higher price tag, and I already own the best of the bunch – the Canon 100-400mm f/4.5-5.6L IS II. I was a little skeptical that Sigma could make a truly competitive lens at such a relatively low price point. I’m happy to report, however, like my first impressions, the Sigma 100-400 C is a lens that exceeded my expectations on nearly all fronts. Interested? Read on…

Prefer to watch your reviews? I’ve got you covered. Check out my full video review here:

Design, Build, and Handling

Sigma did something a little different with their lens announcements for the year in 2017. They simultaneously announced four lenses: the 24-70mm f/2.8 OS, 14mm f/1.8, and 135mm f/1.8 lenses in their “Art” lineup, with the 100-400mm f/5-6.3 OS as the lone entry in the “Contemporary” line. (And no, I still don’t really know what Sigma was going for with the “Contemporary” branding. It makes no more sense now than it did four years ago.). The 100-400 C announcement was somewhat overshadowed by the more exotic ART series announcements, but the 100-400C has the potential to be most important lens in this lineup for many shooters (though few lenses are more indispensable than a 24-70 f/2.8 lens).

Why do I say this? There are three reasons I think the 100-400 C is going to be an important lens for Sigma.

The first is price. The main first party players (Canon, Nikon, and Sony) each have a 100-400mm lens (80-400mm in the case of Nikon), and each of these lenses sell for in excess of $2000 in the US market. The Sony sells for $2500 USD. The 100-400 C? It comes to the market at $799 USD. That’s less than a third the price of the Sony! The reality is that most photographers deal with some amount of financial restraints, so the incredible price of this new Sigma is going to make it very attractive to a number of photographers. I can speak as a person with a kit full of fabulous lenses and attest to the fact that I only occasionally shoot with focal lengths longer than 200mm, so I might be tempted by a lens like this (if it were competent) for the simple reason that I could then spend that difference in price on equipment I might use more regularly. I offer that anecdote as evidence that a competent, reasonably priced alternative to the more expensive first party lenses might appeal to a broader range than just those on a budget.

For the record, I already own Canon’s exceptional EF 100-400L II, which I will use as a benchmark as it is, to my knowledge, the best lens available that covers this focal range.

Secondly, I believe this lens could prove highly successful because of its focal length. The first lens I thought of when I first looked at the 100-400 C in person was that new Canon 70-300 IS II, and it struck me that this could be a credible alternative to the 70-300 variants because it isn’t vastly bigger (7.18”/182mm vs 5.7”/145mm in length, 2.55lb/1160g vs 1.56lb/708g in weight) or vastly more expensive ($250 USD more). Both of these are close enough to allow for some cross-shopping, and I think there will be a number of people tempted by the extra “reach” afforded by the 400mm telephoto end. The 100-400 C also offers some weather sealing, which, to my knowledge, isn’t included on most of the 70-300mm options this lens might compete against.

Finally, I think this lens could prove to be an attractive alternative to the significantly larger and heavier 150-600mm variants. No, it doesn’t have as much reach, but not everyone needs 600mm of reach, and the 100-400 C is much easier to tote around. This lens is about 2.5lb, the 150-600 C is 4.3lb, and the Sport version weights 6.3lb! That makes the 150-600 lenses close to 2x and 3x as heavy. One of the reasons I switched from the Tamron 150-600 VC to the Canon 100-400L II (+1.4x TC) was the portability factor. It just fit into my various bags and backpacks better. I can fit the 100-400 C mounted on a 5D Mark IV in something as small as my Lowepro Toploader 55 AW, something you could never say of one of the 150-600mm lenses.

Add to this the fact that the lens looks better than its price tag and promises to punch above its weight optically and you have a [potential] recipe for success.  Take a look at this video where I break down the build and design:

Sigma’s current design language is excellent. Their lenses are sleek and modern, and, while they are essentially all black, I feel like Sigma does an excellent job of utilizing texture variation to make the lenses seem far from monochromatic. I particularly like the sections that utilize a very fine ribbing that adds both visual flair and added grip. The finish definitely feels a cut above the 150-600mm Contemporary lens, which feels a little cheaper by comparison. The materials are the standard engineered plastics (‘thermal composite’ in Sigma speak) over a metal core and brass bayonet mount, but the feel/finish of the materials feels more premium to me than the 150-600 C.

A definite area of improvement is in the manual focus ring, which feels and moves much better on the 100-400 C. It still feels like a MF ring on an autofocus lens, but the action is quality. The feel of the ribbed ring itself is also good. Its location may not be a favorite for some shooters, as the MF ring is closer to the mount end and the zoom ring is further out. Most photographers prefer the opposite order, but unfortunately there isn’t really a standard for this ring order. The Canon 100-400L II has the zoom ring first, but the Canon 70-300L has the MF ring first.

I wasn’t initially crazy about the shape/profile of the lens hood, which has a fairly pronounced “scoop” near the base. A conversation with a friend within the Sigma organization revealed a very practical reason for the design, and that was for it to be utilized as a push/pull type lens. You essentially can choose to either use the traditional “twist” zoom action or employ the push/pull zoom action if that is your preference. Finding out that the somewhat irregular hood shape had a functional purpose quickly changed my perspective of it, and I can attest that the shape is well suited to quickly gripping and extending the zoom.

The front element features a surprisingly small 67mm front filter thread. That’s a positive in that 67mm filters are both common and inexpensive, but it is also a reflection of the fact that at no point does this lens let in a lot of light. The 150-600mm variants from Sigma have a 95mm front filter (Contemporary) and 105mm front filter (Sport).

The lens features a traditional zoom lock switch near the “C” logo almost directly in the middle of the lens. It has all of the traditional limitations, too, namely the inability to lock at any position save the fully retracted (100mm) position. It also essentially guarantees that the major omission here cannot even be rectified with an aftermarket solution.

That omission is any kind of tripod collar/foot. This is typically considered essential for a lens like this, but Sigma has clearly bet on the assumption that most photographers will use this lens exclusively handheld. While I didn’t often miss the collar for most of my day to day shooting, I REALLY missed it when trying to shoot standardized results and comparisons from a tripod. Without that collar expect the lens to feel very front heavy on a tripod. It is difficult to set an exact framing, as you will mostly have to adjust the tripod with the lens aiming above the target level and then let gravity bring it back down to the desired level. This is far from precise, however, and was a bit of a frustration. Fortunately I am rarely in this kind of situation with this kind of lens in the real world, though I can see this being an issue when trying to use the lens for landscapes.

Some of you could care less about the omission of a tripod collar as it adds up to a lighter lens, but for some this will be a deal breaker. The nature of the lens design also means there isn’t really any room for an aftermarket tripod collar, and the zoom lock being in the one area without anything else prohibits attaching one there as well.

There are four switches located about two inches into the lens. The first gives you options for the autofocus, including the standard AF, then a MO (manual override) which will allow you to manually override the focus result at any point (my standard choice), and then the straight MF (manual focus) option, which will turn off the autofocus motor.

The second switch is the focus limiter, something always welcome on a telephoto lens. I find that the lens is just slightly slow to rack the full range of focus, so employing this selectively/appropriately will make a difference. Once again there are three choices: Full, 6m to Infinity, and 1.6m-6m.

The third switch enables control over the OS (optical stabilizer), and includes OFF| Position 1 | Position 2 choices. Position 1 is the standard balanced performance, while Position 2 disables one axis of stabilization for enhanced panning action.

The final switch allows you to access two previously programmed “Custom” functions. You enter these through the Sigma USB dock and the Sigma Optimization Pro software. This includes the ability to customize the AF performance (Fast AF, Standard AF (balance between speed and smoothness), and Smooth AF (optimized for video). You can also set a custom focus limiter setting in a second menu. The final option to program to a custom mode is the OS performance. Three options are present: Dynamic View (prioritizes smooth viewfinder), Standard (balance between the two extremes), and Moderate View (prioritizes applying stabilization to the image capture and focuses less on steadying the image in the viewfinder). I can’t say that I saw any major difference when applying these customization changes, but you might. I consider the custom modes to be a nice feature at this price point, however.

All in all there is only one thing to complain about, and that is the lack of a tripod collar, and, in particular, the inability to add one as an optional accessory. Sigma clearly made a decision to eliminate that from the design, but that will alienate at least a percentage of the market. Beyond that, however, there is little else to complain about. Everything else about the lens felt better than its price point suggests.

100-400 C Optical Performance

Let’s get the weak point dealt with first: this lens is definitely on the “slow” end in terms of aperture. It adopts the same variable aperture of the bigger 150-600mm lenses, except that maximum aperture of f/5 only lasts for a heartbeat. By 114mm the maximum aperture closes to f/5.6, and further closes to f/6.3 from 234mm on. Like the 150-600 variants, this is a lens that needs a good amount of light to thrive. This is one area where it really suffers in comparison to the Canon 100-400L II, which, while also variable aperture, lets in quite a bit more light at any focal length.

Lens f/4.5 f/5 f/5.6 f/6.3
Sigma 100-400 C  N/A 100-113mm 114-233mm 234-400mm
Tamron 100-400 VC 100-137mm 138-184mm 185-280mm 281-400mm
Canon 100-400L II 100-134mm 135-311mm 312-400mm  N/A

As this chart shows, you are going to need quite a bit more light with the Sigma than with the Canon, which actually doesn’t reach it’s smallest maximum aperture until fairly late in the focal range.  The rival lens from Tamron also does a bit better in this area, with a wider maximum aperture on the long end and the ability to hold onto the larger aperture values a little longer.

One thing that stood out to me is the nice level of saturation on the images I shot from the lens, even at maximum aperture values. It doesn’t need to be stopped down to provide saturation and contrast; you can get great results right from wide open. This helps to offset the slow maximum aperture values somewhat; there is no real need to stop the lens down to get maximum performance from it. Images look great right out of the box from the lens.

I did a direct comparison with the Canon 100-400L II lens, and, frankly, I expected the Canon to dominate the Sigma. It costs more than 2 ½ times as much and is the best lens in the class. What I found surprised me.  To fully appreciate this I recommend that you watch this video:

At 100mm and a comparison shot with mirror lockup, on a tripod, and Live View 10x focused the Sigma unquestionably had the optical advantage across the frame. I tried it with both lenses wide open (f/4.5 for the Canon, f/5 for the Sigma), and then stopped them down to equivalent apertures. The Canon caught up in the middle at about f/5.6, but the Sigma was demonstrably sharper near the edges of the frame at all tested apertures. It also showed less chromatic aberration and better contrast. Wow!  Each of the comparisons to come are pixel level crops from the far left, center, and then far right corners.

Comparison with both lenses wide open at 100mm:

With both lenses stopped down to f/5.6:

At 200mm the advantage shifted to the Canon, though it was marginal and the Sigma produced very close image quality stopped down. The difference between the lenses was only apparent at pixel level, and barely visible there.

At the most crucial 400mm position the Canon’s maximum aperture is f/5.6 while the Sigma’s is f/6.3. With both lenses wide open I was shocked to find a [very] slight advantage for the Sigma! When I stopped the Canon down to f/6.3, I felt it was ever-so-slightly better, but with both stopped down to f/8 the slight advantage shifted back to the Sigma. I was blown away by this result, as often budget telephotos fall apart on the long end.

The reality is that there is very little optically to distinguish these two lenses. The Sigma vignettes much more heavily compared to the Canon, and the 100-400L II also has an aperture advantage at every focal length, but the Sigma shows similar and even superior sharpness and contrast at various points. The 100-400 C also showed less CA in my testing. All in all I found this an extremely surprising result and have to really commend Sigma for putting together such a high performing lens at such a great price.

I was also pleasantly surprised by the bokeh quality from the lens, which seemed every bit as nice as that from the Canon.

Optically there are only two real weaknesses – a very slow maximum aperture and some vignette, but if you can live with these (and one other issue to come), you will find a lot of lens for your money.  I would recommend visiting the Image Gallery to see a many more images and get a sense for yourself!

APS-C Performance

I realize that many APS-C (crop sensor) shooters will be interested in this lens, so I spent some time with it mounted on my Canon 80D camera body. Not every lenses translates well to an APS-C body, but the 100-400 C did great in this application. On a Canon body (1.6x crop factor) the lens has a full frame equivalent focal length of 160-640mm, so it offers a truly impressive amount of reach in this application. I was very pleased with the image quality from the lens on APS-C, and so no new optical flaws introduced that I could tell. Details continue to be good, no new chromatic aberrations appeared, and vignette is of course reduced by the crop factor.

Here are a few samples from 400mm, f/6.3, with near pixel level crops:

I see no reason why APS-C shooters should not strongly consider this lens. In many ways I think it makes more sense here than the 150-600mm lenses in many situations as the wide end remains more useful and the 600+mm equivalent long end is plenty in most situations. I also think the image quality (for me) held up better in the transition to crop than what I’ve seen from most of the 150-600 variants. This lens is much, much easier to pack around, too. I feel like it will balance much better than the larger first party 100-400mm lenses on any camera body save, perhaps, a 7D Mark II or equivalently sized body.

I’ve got an APS-C Image Gallery here:

I’ll comment further on the autofocus performance in general in a moment, but I will add here that I found autofocus performance roughly similar on the 80D to the 5D Mark IV. Accuracy was very good on the 80D, and speed was adequate for most things.

Autofocus Performance

The first thing to note is that while this lens has been on the market for less than a month, there has already been a firmware update specifically addressing some autofocus improvements. This is somewhat of a two-edged sword, as on one hand it indicates that Sigma is being proactive about supporting the lens. That’s a good thing. On the other hand I’m a little concerned by the message that is sent by this: it feels a bit like the lens might have been rushed to market before some of the final refinements were made. This isn’t a problem for owners of the Sigma USB dock, but leaves those without either having to purchase one or feeling the need to send their brand-new lens back to Sigma for the update.

Those reservations aside, I was encouraged during my calibration process to see nicely repeatable results and a linear pattern of adjustment. I used the USB Dock to input calibration at different focal lengths and focus distances, and saw the kind of pattern that I like to see (one that makes sense). The lens definitely required some adjustment, but didn’t show any of the random misfocus results that plagued some of the earlier Sigma lenses (18-35 ART, 35mm f/1.4 ART, 50mm f/1.4 ART) that I’ve reviewed. I would encourage you to check out my video series on how to properly do lens calibration if you are unfamiliar with the process here.  There images show the difference in results after calibration along with the [lens specific] values that I plugged in.  Note that these values won’t work with your lens/body combination but are simply shown to illustrate my process.

In the field I was further assured. I saw good, accurate results there as well, with images nicely focused in both One Shot and AF Servo modes. I’ve actually had pretty good success with Sigma’s telephoto lenses in this area. Autofocus accuracy is a strength rather than weakness for this lens.

There is only one area that I have a bit of concern, particularly for those who want to shoot sports or other higher speed targets, and that is the focus speed. I found the lens tracked acceptably in AF Servo with moderately speed subjects once I had focus locked, but I did have an issue with the lens picking up an object already in motion. This was using a Canon 5D Mark IV, which has an exceptional autofocus system.

I ran a number of tracking tests that I consider to be a “torture test” – a small dog charging towards the camera at full tilt. The Canon 100-400L II has an excellent focus system, and yet it doesn’t always pass this test. But it definitely showed its superiority here, where I was sometimes able to track a whole sequence across many frames in AF Servo mode (one sequence had 17 frames over a period of less than three seconds, all well focused). The Sigma, however, often only achieved a few frames in focus in similar conditions. At times it would lose focus and I wouldn’t be able to achieve a fresh lock, so pressing the shutter did nothing. Focus would also lag sometimes behind the subject, as if the focus motor wasn’t quite keeping up.

I would definitely recommend utilizing the focus limiter when possible, as while the lens is quick to make small to medium adjustments, it takes a while for it to rack the full range of focus. I would guess that the HSM motor doesn’t have as much torque as what the Canon 100-400L II that I own does.

Bottom line is that the focus system of the 100-400 C didn’t work nearly as well for higher speed subjects, and if you want to shoot sports, bird in flight, or fast moving wildlife I’m afraid you will be better served spending more money for the first party options.

For most of the subjects that I typically shoot, the lens works great, but I did have a few situations where I was left wishing for a little more focus speed in one shot mode. I also encountered a few isolated situations where (much like the 150-600 C) the 100-400 C didn’t want to lock focus at all. I do a lot of hiking (a great way for me to mix business and pleasure!), and so often will shoot scenes on trails where the lighting is mixed. The photo below particularly stands out, because I stood in what seemed to be plenty of light and tried to find a high contrast edge to lock onto on the foreground leaves with the defocused trail beyond. I was first using a grid with about 10 focus points active, and it simply wouldn’t lock focus. I switched to the finest point on my 5D Mark IV – just the single center point active and tried to put it right on leaf edges or something with higher contrast. No luck. I had to play around with it for probably 20-30 seconds with a little manual override before I finally got it to lock focus, though I had to switch to another point to focus on to make it work. The final result is focused just fine, but the process showed the lens hesitation in that kind of setting.

Bottom line is that the combination of a relatively slow maximum aperture and an autofocus system that isn’t top shelf (at least in terms of speed) is perhaps the only place where the budget origins of this lens are betrayed and could be a limiting factor for someone who is serious about moving wildlife or sports.

Sigma 100-400 C Lens Stabilization

Any lens with a focal length reaching out to 400mm is going to need a good image stabilization system, and that is particularly true of lenses with small maximum apertures. Sigma has outfitted the 100-400 C with its Optical Stabilizer (OS).

Sigma 100-400 C, handheld using careful technique.

  • At 400mm, 1/25th of a second. All six shots (one extra) were acceptably sharp with about half of them perfectly sharp.
  • At 400mm, 1/15th of a second. All shots were acceptably sharp with about half of them perfectly sharp (no change).
  • At 400mm, 1/10th of a second. 1 shot blurry, 3 shots acceptably sharp, and 2 perfectly sharp.
  • At 400mm, 1/6th of a second. 2 shots extremely blurry, 2 moderately blurry, 1 shot acceptably sharp, 1 shot perfectly sharp.

The Sigma OS is less effective at stabilizing the viewfinder image, but, much like Tamron’s “Capture Priority” VC setting seems to do a good job stabilizing the actual capture.  Here’s one of the “keepers” I got at 1/6th second.

Canon 100-400L II, same process.

  • At 400mm, 1/25th of a second. 1 shot acceptably sharp and 5 shots perfectly sharp.
  • At 400mm, 1/15th of a second. 1 shot slightly blurry and 5 shots perfectly sharp.
  • At 400mm, 1/10th of a second. 1 shot blurry, 3 shots acceptably sharp, and 2 perfectly sharp.
  • At 400mm, 1/6th of a second. 3 shots extremely blurry, 3 shots acceptably sharp.

The two stabilizer systems operate slightly differently, but produce results more similar than different. I slightly favor the way the Canon image stabilizer works, but the end result isn’t all that different.

Conclusion

I really do feel like Sigma knocked this one out of the park…for many shooters.  There are really only two things that should give you pause to consider: 1) do you need a tripod collar?  2) do you need to track fast moving action (particularly subjects that quickly move towards you)?  If you are primarily a handheld shooter, then the reasonable weight of this lens is going to make it a favorite for you.  If you will shoot occasional action and don’t need high end tracking, then the accurate AF system should meet your needs.  I feel like the only thing that holds this lens back from being absolutely exceptional (and a very serious competitor to far more expensive first party lenses) is the unexceptional tracking performance.  Still, I had good accuracy in One-Shot AF mode for everyday shots, and there is no question the lens has fantastic image quality that is on par with the top tier first party lenses.  If you are on a budget and don’t need the absolute best AF system, I think the Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary should jump to the top of your list.

Pros:

  • Fantastic price to performance ratio
  • Excellent image quality across the focal range
  • Good color and contrast
  • Nice build quality for the class, including some moisture resistance
  • Accurate autofocus in One Shot mode
  • Reasonable size and weight
  • Effective image stabilization system

Cons:

  • AF system doesn’t track fast motion well
  • No tripod collar included; no room to add one
  • Particularly small maximum aperture across focal range
  • AF can hunt in dim light

Sigma 100-400mm f/5-6.3 C Image Gallery

Dustin Abbott

June 8th, 2017

Lost in the midst of the higher profile ART series announcements was the announcement of a lens that makes a whole lot more sense for many photographers.  The Sigma 100-400mm f/5-6.3 OS Contemporary helps to fill an important gap – a more affordable, compact way to get a significant amount of reach.  The Canon 100-400L II, while a fantastic lens (and one that exists in my own kit), costs north of $2000, as do the Sony 100-400 G and Nikon 80-400.  The Sigma?  It can be had for right under $800, making it a tremendous value.  The question will be whether or not the inevitable compromises to hit that price point will show up during my review.  First impressions are quite favorable, and stay posted for my review coverage as things progress.  In the meantime, however, enjoy these galleries of looks at the lens along with images I’m taking with the Sigma 100-400 C.  Check back often for new updates!
