Viltrox AF 50mm F2 AIR FE Gallery

Dustin Abbott

April 2nd, 2025

Viltrox’s series of small, lightweight, and yet surprisingly high performing lenses is called the “Air” Series. We’ve seen 20mm F2.8 and 40mm F2.5 full frame lenses along with a truly excellent series of APS-C lenses, including the 25mm F1.7, 35mm F1.7, and 56mm F1.7. The AIR lenses have all been pretty uniformly excellent, combining great optics with small, lightweight (howbeit very simple) designs and equally low price tags (all under $200). Viltrox is back with yet another AIR series lens, and this is another full frame option. While the 20mm may still stand as the most useful lens for travel, the new Viltrox AF 50mm F2 AIR is easily the best performer yet in the series, and is very possibly the sharpest “nifty-fifty” style lens that has even been made. It seems to best even the impressive Sigma 50mm F2 DG DN from their iSeries, a lens I thought was very impressive. There’s no question the Sigma lens has a much higher degree of build quality and functionality, but at a price tag more than 3x higher than the sub-$200 AIR 50mm, I suspect that Viltrox will have another best seller on their hands. It is the new lightweight 50mm to grab (just 205g)? Find out my thoughts by watching the video review, reading the text review, or just enjoying the photos in the galleries.

Viltrox AIR Series Reviews:

__________________________________________________________________________________________________

I probably don’t need to say much about the 50mm focal length at this point. I have probably reviewed more 50mm lenses than any other. It would be easy to ask the question, “Do we even need another 50mm lens?” The short answer might be “no”, but I suspect there will always be room for a lens like the AIR 50mm, as, shockingly, it is one of the sharpest 50mm lenses that I’ve tested.

The AIR lenses are great! Much like Samyang’s “Tiny series”, these lenses are for those who don’t care about bells and whistles and just want a lightweight, high performing lens. This won’t be the series for those looking for aperture rings, buttons, or rings, but if you want a light, tough, high performing lens at a great price, then grab a Viltrox AIR series lens!

Sony FE 400-800mm F6.3-8 G OSS Gallery

Dustin Abbott

March 31st, 2025

I have owned (and loved) the Sony FE 200-600mm F5-6.3 G OSS since reviewing it back in 2020. Sony took a different tack than most competing telephoto zooms by opting for an internally zooming lens, and, while that meant that the lens was larger than lenses like the Tamron 150-500mm or the Sigma 150-600mm, it also made for a lens that handled better in the field, allowing for near instant zooms, more consistent balance, and more consistency in handling. When your eye is in the viewfinder, it’s great to have everything stay in the same place for muscle memory. What’s more, that lens had great autofocus, great image quality, and was generally a lot of fun to use. Sony has now expanded on that formula with their newest lens – the Sony FE 400-800mm F6.3-8 G OSS – by shifting the zoom range 200mm further, and, in the process, creating a whole new class of lens. 600mm has been the previous limit for a lens like this, so getting up to 800mm opens up all kinds of new horizons…and the fact that it can be used with teleconverters allows for some pretty wild amounts of reach. Does the 400-800G limit up to the standard set by the 200-600G? We’ll explore that in both the video review and text reviews, or just enjoy the photos in the galleries below.

__________________________________________________________________________________________________

While lenses like this are not for everyone, those who are always looking for a little more reach are going to be delighted with the 400-800mm G.

The 200-600G could reach up to 840mm if you used a 1.4x teleconverter, but your maximum aperture would be F9, so the 400-800G is actually the brighter option for shooting in and around 800mm. The 400-800’s range can be stretched out to 1120mm with a 1.4x, with a maximum aperture of F11. You can reach up to an unbelievable 1600mm with a 2x teleconverter, though I didn’t have one on hand to test with (I’m typically not a big fan of 2x teleconverters). Maximum aperture will be a rather dim F16, so you’ll need lots of light (and probably a slower moving subject) to make that work.

But we’ve never seen a zoom lens that reaches 800mm quite like this, and certainly not one that is quasi-affordable at roughly $2900 USD ($4100 CDN). Does that make this droolworthy lens worth pursuing? Take a look at the photos and see.

Sony FE 400-800mm F6.3-8 G OSS Review

March 31st, 2025

I have owned (and loved) the Sony FE 200-600mm F5-6.3 G OSS since reviewing it back in 2020. Sony took a different tack than most competing telephoto zooms by opting for an internally zooming lens, and, while that meant that the lens was larger than lenses like the Tamron 150-500mm or the Sigma 150-600mm, it also made for a lens that handled better in the field, allowing for near instant zooms, more consistent balance, and more consistency in handling.

Thanks to Sony USA for sending me a review loaner of this lens. As always, this is a completely independent review. *The tests and most of the photos that I share as a part of my review cycle have been done with the Sony a7RV along with the Sony Alpha 1 that serve as my benchmark cameras for Sony lenses. You can visit the product page for the 400-800G here.

__________________________________________________________________________________________________

It’s a curious quirk of mathematics, but while both the 200-600G and 400-800G cover an identical number of potential focal lengths, the former is a 3x zoom ratio and the latter just a 2x zoom ratio. Moving deeper into telephoto territory also dictacted a shift in maximum aperture (otherwise the lens would have been prohibitively large and expensive). Whereas the maximum aperture of the 200-600G varied between F5 and F6.3, the new 400-800G shifts to F6.3 on the wide end as the maximum aperture and F8 on the telephoto end. More specifically:

  • 400-482mm = F6.3
  • 483-594mm = F7.1
  • 595-800mm = F8

Because Sony only shows one-third stop aperture changes, there are only 3 different maximum apertures in the zoom range. So yes, the new lens is less bright at 483-600mm than the 200-600G (F6.3), but only by one third stop. That being said, the maximum aperture for more than 50% of the zoom range is F8, which isn’t particularly bright. This will be a lens best used in good lighting conditions, which means either outdoors or under very good stadium lights.

The 200-600G could reach up to 840mm if you used a 1.4x teleconverter, but your maximum aperture would be F9, so the 400-800G is actually the brighter option for shooting in and around 800mm. The 400-800’s range can be stretched out to 1120mm with a 1.4x, with a maximum aperture of F11. Here’s a shot with that combo.

That gives you can idea of just how far away these geese were!

You can reach up to an unbelievable 1600mm with a 2x teleconverter, though I didn’t have one on hand to test with (I’m typically not a big fan of 2x teleconverters). Maximum aperture will be a rather dim F16, so you’ll need lots of light (and probably a slower moving subject) to make that work.

But we’ve never seen a zoom lens that reaches 800mm quite like this, and certainly not one that is quasi-affordable at roughly $2900 USD ($4100 CDN). Does that make this droolworthy lens worth pursuing? Let’s take a closer look…

Build and Handling

It’s moments like these when I’m not quite sure where the line between Gold (G) and Gold Master (GM) lies. This looks and feels like a premium product, with a high grade of build quality, a deep suite of features, and thorough weather sealing. I’ve been impressed by just how GM these two G telephotos lenses look and feel.

As you can see, the two lenses have a very similar design, though the 400-800G just scales everything up. The size difference isn’t even as significant as this photo suggests, as the hood is actually the thing that has grown the most. If I remove the hood, you can see that the 400-800G is about an inch longer than the 200-600G.

To be more precision, the dimensions are 11.98 (D) x 34.6 cm (L), or 4.72″ in diameter and 13.6″ in length for the new lens, while the older 200-600G measures 11.15 x 31.8 cm or 4.39 x 12.52″. That’s nearly 17% bigger in overall volume, which is not too bad for a lens that reaches all the way to 800mm. The weight is 2.47kg, or 5.45lb, which is hefty but not outside the realm of being handholdable. The 200-600G weighs in at 2.11kg and the Sigma 150-600mm Sport weighs 2.1kg. Probably only the dedicated are up for using any of these lenses handheld for any length of time, though that’s almost exclusively the way that I used the lens.

On a practical note, I did find the balance point when on a tripod to be better with the 200-600G vs the 400-800G. It took more work when trying to align my test chart with the 400-800G as it was more likely to drop forward after framing.

The front filter size has increased from 95mm to 105mm, so if you’ve invested in 95mm filters on the 200-600G or a similar lens, you may need to rebuy.

The lens hood is deeper, so Sony has added a door to the hood to allow for easier rotation on a filter like a circular polarizer.

The lens hood is large, but also fairly lightweight. It has both a locking button (large and nicely executed) along with a rubberized front surface that makes for a logical place to place the lens or lens/camera combination…as in the first photo in this section.

There is a section before the tripod collar that has a bank (two banks?) of switches. They occupy the same plane but there is a line of division between them. The top section contains the AF | MF selector, a switch allowing for full time DMF (manual override regardless of what focus mode you’re in), and a three position focus limiter that allows for the full range of focus, from minimum focus to 10 meters, and then from 8 meters to infinity.

On the note of minimum focus, the lens can focus as closely as 1.7 meters (5.6 feet) at 400mm and then only as close as 3.5 meters (11.5 feet) at 800mm. Maximum magnification is 0.23x and is gotten on the 400mm end of the zoom range.

The second bank of switches is dedicated to the OSS, or Optical Steady Shot. The first switch is a simple ON | OFF, and this will override any camera setting for in camera stabilization if so equipped. The systems will work somewhat in harmony, but it is either both or neither. The truth of the matter is that in camera stabilization is rarely very effective at long focal lengths like this, however.

The second switch here is for three different modes for the OSS. The first is the standard mode, while mode 2 is for panning, and mode 3 emphasizes viewfinder stabilization to help with framing.

You can see a radical difference in trying to handhold the shot at these kinds of focal lengths when the stabilization is turned off. I could not find a rating for the stabilization in terms of stops, but the stabilization seems reasonably effective.

I tried a battery of handholding at 800mm, first at 1/8th second (ISO 800), then at 1/30th second (ISO 1600), and finally at 1/60th second (ISO 3200). I didn’t have any success in getting stable results until 1/60th second. That’s about 4 stops of assistance (see the final shot for a nice stable result).

The tripod collar/foot section comes next, and it follows the same formula as the one found on the 200-600G. The foot itself is removable, but the collar is fixed. You can rotate it by releasing the tension via a knob found on that section. The foot itself is has a standard 1/4″ and 3/8th” holes for attaching quick release style plates, but the foot is not natively Arca-compatible.

I never quite understand the lack of Arca grooves, as both Sigma and Tamron seem perfectly capable of making Arca-compatible tripod feet.

There are attachment points on either side of the tripod collar for attaching a carrying strap (included). The lens also comes with a large, padded case for storage. *My loaner is from Sony, and didn’t come with retail packaging, so I can’t picture these items.

There are two rings on the lens, the first (slimmer) being the manual focus ring. This ring has a rubberized grip and moves nicely. There’s a decent amount of damping, and the ring works well either for manual focus or DMF override. The most useful application is when photographing something like birds when focus grabs a branch in the foreground instead.

In between the manual focus and zoom rings there are three function buttons. These are at 3 of the cardinal positions around the lens, with a Sony logo at the fourth position. These are redundant buttons, meaning that each one will perform the same function (which is assigned in the camera menu). They are repeated at a variety of positions to be sure that one is close to hand whether shooting in horizontal or vertical modes.

The zoom ring is the real standout. The internal zoom design means that you can near instantly swing from one end of the zoom range to the other. I love the precision, not having to worry about zoom creep, and that the balance of the lens remains the same. This is where the additional size of the lens for storage really pays off.

Up front we have a fluorine coating on the front element along with the aforementioned 105mm filter threads.

This is the final touch on the thorough weather sealing, which starts with a gasket at the lens mount and then is backed up by a number of seals throughout the lens. I count at least 21 seals in total.

This is a professional grade lens with high quality build. The body seems to be a mix of metal alloys along with some engineered plastics. The lens feels tough and durable, and I can attest that my own copy of the 200-600G (now five years old), has definitely been that.

As noted, the 400-800G is fully compatible with Sony’s 1.4x and 2.0x teleconverters. In most situations I would recommend sticking with the 1.4x and avoiding the 2.0x. There are too many compromises introduced by 2.0x teleconverters in most situations, and the challenge of focusing with F16 as a maximum aperture could prove vexing. Third party lenses on Sony are purposely excluded from teleconverter compatibility, and, while I disagree with this policy, it is this case one potential asset for this lens over another.

This is a big, heavy lens (as you probably already knew), but the tradeoff is a very well constructed lens that is actually very nice to use in the field…if you can manage the weight.

Autofocus for Stills

*Before entering the formal test sections for autofocus and optics, I do want to add a general caveat that the extreme nature of a lens like this means that all of my typical test processes go out the window. I don’t have enough room indoors to perform them, so everything has to get reinvented outside…where I have less control over certain variables.

Pairing a Sony telephoto lens with a Sony sports camera is generally a delight. Combine a lens like the 400-800G with one of the a9 or a1 bodies and it will feel like enabling a cheat code. Tracking is just so good! Sony has employed dual linear motors to drive focus here, and that helps give the lens the speed it needs. I tested focus on an Alpha 1 body, but Sony adds this for those shooting with the lower resolution but ultra fast a9III: “Tracking easily keeps up with the 120 fps maximum burst speed of the α9 III, and continues uninterrupted even while zooming so important moments are not lost.

In my formal tests, I found that focus speed was faster at the 400mm than at the 800mm end, with the former being basically instant and the latter having just a slight pause as intertia builds.

There’s plenty of speed for tracking everything from sports to birds in flight…with one caveat we’ll soon address.

I shot a burst of 138 shots tracking a Canada Goose soaring low over an ice floe where many other geese were gathered. Despite having many subjects (and occasionally having foreground bushes partially blocking my view) tracking was csonsistently excellent, keeping the goose in perfect focus all throughout the burst.

There is a challenge, however, and that’s you are going to need good light if your subject is moving. I tested tracking of a running subject in a fairly well lit field house, and tried to bias everything as much in the lens’ favor as possible. I shot near 400mm to keep maximum aperture at the brighter F6.3, jacked the ISO up to 6400, and even so I was getting shutter speeds no faster than 1/200th of a second and sometimes slower. That just wasn’t fast enough to reliably stop the action, so while focus and tracking were good, most of the shots are impacted by some motion blur. There’s a specific point int he sequence where the runner has landed from one stride and hasn’t taken off on the next, and those tended to be the most stable shots.

This is why 500mm and 600mm F4 lenses cost so much and are so big – getting sufficient light gathering in a long telephoto is a real challenge.

Focus remained good throughout the sequence, however, moving forward in a nice linear fashion so that I continued to get accurate focus even when the runner was relatively near the camera.

I saw enough to assure me of two things: Sony really knows how to do autofocus and this is definitely an outdoor lens!

I always hate when long telephotos get released during Canadian winters (which it seems like they invariably are), as it makes find subjects extremely difficult. In this case, because the river is only open in a certain channel and there is a lot of unstable ice near the edge, I couldn’t really get close to any waterfowl subjects on this particular day. That meant a lot of 800mm shooting, and you can see that even with that extreme magnification I wasn’t all that close to my subject. Because I had only one angle, it also meant that the sun was on the wrong side of these geese, leaving the side of their heads facing me in shadow. A black eye on a black background in shadow is hardly a high contrast subject, so I was very impressed to find that eye detection worked pretty consistently, and I was able to get accurately focused results.

In better light (and at a different location where I could get closer) I had no problem getting the shutter speed I needed to perfectly stop action.

Slow subjects are no problem, obviously, and this shot of Ferrari (658mm, F8) shows perfect focus.

Bottom line is that the limiting principle won’t be autofocus…but it could possibly be the amount of available light.

Autofocus for Video

Sony has worked hard at making their lenses (and cameras) to be equally good whether doing photo or video work. I did my formal tests at the 400mm end, as the working distance at 800mm just requires far more room than I have easy access to. I found a nice level of damping, with no visible steps and smooth transitions from one subject to another.

At 400mm, focus breathing is extremely well controlled, even with Sony’s “Focus Breathing Compensation” turned off. You can see from the third stills capture below that the size of the distant subject stays mostly the same regardless of being in or out of focus.

My hand test went fine, though it was very odd to be doing it at a distance of about 40 feet rather than 6. The amount of compression at 400mm makes it feel like there is very little distance between my hand and my face, but I could see that focus was transitioning smoothly back and forth.

I tracked some turkeys walking around my backyard, and focus mostly kept steady on them as they moved in an agitated fashion (they knew I was there). There was one occasion where focus did shift to a foreground bush momentarily, but it mostly stayed where I wanted.

Overall I would say that focus works well in video as well. The extreme nature of the focal range does provide some challenges, but it isn’t because of the autofocus.

Image Quality Breakdown

As you would expect, the complexity of the optical design has grown from the 200-600G. Whereas that lens had an optical design of 24 elements in 17 groups, the the Sony FE 400-800mm F6.3-8 G OSS is one of the most complex optical designs I’ve seen, with 27 elements in 19 groups. That matches the Sigma 60-600mm F4.5-6.3 DN Sport lens, another extremely complex lens (some 50mm primes have as little as 5 or 6 elements!). The 400-800G’s optical design includes 6 ED (Extra-low dispersion) elements. The MTF chart included below gave me a little chuckle, as Sony tends to show both wide open and then F8 results. That fine for the first row, which includes first the 400mm results at F6.3 and then at F8. The bottom row, however, shows the 800mm performance, and since the maximum aperture is F8, it actually shows the same results twice.

Those results are pretty impressive, though, showing an extremely sharp center (over 90%) at 400mm and nearer to 100% at 800mm. The midframe is also impressive at both focal lengths, with some fade in the corners (arguably far less important in a lens like this). That fade is pretty consisent on both the “radial and tangential” axis at 400mm, though at 800mm the corner drop is almost entirely on the tangential plane.

The key advantage to a telephoto zoom lens is that it gives you a lot more control over framing. Often shooting with a prime lens is frustrating either because you are too close or too far. A zoom lens doesn’t solve all of those problems, but it means that you have both this extreme:

And then this extreme as framing alternatives:

800mm was too tight of framing for the shot below, so I was able to back off to 740mm to get the composition I wanted, something I wouldn’t be able to do with a prime.

A zoom lens is extremely useful, particularly if you have a fixed location to work from.

So how about the optical details?

I saw a minimal amount of longitudinal type chromatic aberrations in some real world shots, mostly showing up as some blue-green fringing in high areas of contrast, like this:

I didn’t see much of it in my shots of geese with shiny ice around them, however, leaving me to believe it won’t be any problem in real world shots.

I didn’t really see any lateral style chromatic aberrations near the edges of the frame either on my chart or in real world results.

I only set up one test chart outside (and ended up regretting that a bit, as it got a little dirty), so I’m going to pull my findings on vignette and distortion from my main chart. Here’s how far I had to be away to test 800mm:

No, I don’t have that kind of room in my basement! And yes, we still have snow (March 21st). I actually cleared some of the snow to make sure that I had enough space to test the full range of the lens.

Distortion is consistently of the pincushion variety, with some ebb and flow throughout the zoom range. Here’s a look at 400mm before and after correction.

The pincushion isn’t bad at 400mm, requiring just a -4 to correct, and you can see that it corrected in a linear fashion leaving straight lines on the frame around my chart. Vignette is also pretty minimal, with no more than a stop of peripheral shading (I used a +30 to correct).

In the middle of the range, the distortion increases a bit (-6), but the vignette remains extremely low.

At 800mm the distortion needs only a -3 to correction, and vignette remains pretty neglible. Nothing that is going to cause anyone any problems; I never saw anything more than about a stop of vignette, which frankly you just won’t notice in real world shots. This shot of a turkey was taken at 681mm, F8, and there has been no correction. Note how bright the snowy bottom corner is.

That big front element is letting in plenty of light to the corners of the image circle.

So how about sharpness and contrast? I did these tests on my Sony a7RV and its 61MP sensor. Crops are shown at roughly 200% magnification (as always) to highlight strengths and weaknesses. If you aren’t experienced with long telephoto lenses, know that sharpness results are much more dependent on environmental conditions. You are often shooting at much great distances, and there are many more variables like thermal pockets that cause heat shimmers and other optical disturbances. Shooting with long lenses requires skill and developing a sense of what works and what doesn’t…often some trial and error. I shot my test chart results multiple times to broaden the sample size for this reason. I used my most stable tripod and also moved from a 2 second timer to a 10 second timer to reduce vibrations. I’ve mixed and matched here to show the best results I found.

You’ve already seen the test chart earlier, so I’ll go right to the deep crops. This is 400mm, F6.3, with crops from the center, mid-frame, and bottom right corner.

Detail is good, though contrast isn’t exceptional. To put this in perspective, however, here’s a comparison to the 200-600G, taken within a few minutes of each other (so similar lighting conditions).

What I found is that the 400-800G was very slightly better – a tiny bit more sharpness and contrast – all across the frame. I was pleasantly surprised by that, as I’ve always considered the 200-600G to be one of the best lenses I’ve tested in this class.

The MTF suggests a mild improvement when stopped down to F8, and I’m sure that in a lab under perfectly controlled conditions that’s true, but I didn’t really see much of a difference in any of my tests. here’s a real world example and crop at 100% that shows good detail and mostly good contrast at F8.

This is a variable aperture lens, and that affects not only the maximum aperture; it also affects the minimum aperture. This varies from F36 on the wide end to F45 on the telephoto end. I would shoot through F11 and try to avoid anything smaller than that as diffraction will definitely play havoc with resolution and contrast.

At 500mm the maximum aperture is F7.1, but I do see a bump in performance…particularly in contrast relative to 400mm.

600mm felt a little softer to me than our sharpness peak at 500mm. We have reached the smallest maximum aperture of F8 by this point.

Checking back in with the 200-600G, I found that comparing across multiple samples left me feeling that while there is some give and take, contrast favors the 200-600G by a small margin.

The truth of the matter is this is probably a matter of splitting hairs, however, as unless you were looking at this ridiculous level of magnification with them side by side (as I have here), you probably wouldn’t notice the difference.

This real world shot of Ferrari shows that while contrast isn’t off the charts, there’s a nice amount of detail being resolved at 600mm.

Moving on to 800mm shows decent resolution but lower contrast wide open. What’s interesting is that even a very mild stop down to F9 (one third stop) has a pretty dramatic effect on contrast. Here’s a look at the center:

Then the corners…

In both cases you can definitely see a noticeable difference.

I decided to see if that bore out in the real world. It definitely did. I used this as my test subject (nice and flat):

In both the cropped areas below, the F9 result is noticeably more contrasty than the F8 result.

So pro tip: if you buy this lens, don’t hesitate to stop it down that one third stop. You’ll get much better results at very little light gathering penalty.

And frankly, I feel like real world results at 800mm could use that bit of a boost. Detail and contrast are good but not great at F8:

That little boost definitely gives you the advantage over using the 200-600G and the 1.4x teleconverter. That combination can get you to 840mm with a maximum aperture of F9, but as you can see, the 400-800G is noticeably better than the TC combination at F9:

My conclusion is that the resolution may not be “wow” at 800mm, but it is better than what any of these type lenses have achieved previously (by reaching there with a teleconverter). What’s more, you are avoiding the inconvenience and expense of the teleconverter. Currently the 1.4x Sony TC costs $548, and that definitely would help close the $900 gap between the 200-600G and the 400-800G.

How about the bokeh? My answer to that is, “it depends”. When you are a longer distance to your subject (and thus the background is less blurred out), I find that the background gets a bit busy, with some jitteryness in the transition zone.

Ditto with the foreground obstructions that you will often encounter when birding.

Likewise here I found this complex background to be rather unappealing.

In more favorable ratios, however, where the subject is closer and the background is further, the bokeh looks much more pleasing.

This shot is somewhere in between, with the subjects being at a medium distance, but the background is a little less complicated.

My conclusion is that like many of these type lenses, the 400-800G is more optimized to try to get as much sharpness as possible rather than delivering amazing bokeh. If you want amazing bokeh at 800mm, grab the $13,000 Sony 600mm F4 GM and use a 1.4x TC on it. There’s only so much heavy lifting that a zoom lens like this can do.

I didn’t point the 400-800G right into the sun, but I also never saw any real flare issues when panning across it while tracking. You will see some loss of contrast at certain positions with intense midday sun, but it is obviously very easy to avoid these situations with such a narrow angle of view.

This isn’t a flawless lens optically, but neither does it have any significant flaws. Any optical shortcomings I see are put into perspective when I compare it to a lens that I think to be very good and have taken some amazing photos with. It lets me know that if I had this lens in similar conditions, I could expect as good or even slightly better images. Check out the image gallery if you would like to see more images.

Conclusion

Lenses like the Sony FE 400-800mm F6.3-8 G OSS are going to be completely wasted on a large swatch of the photography world but will immediately send a certain subset to place a preorder as quickly as possible. Many will find a lens like this too big, too heavy, and too expensive, and that’s fine. And even if you aren’t one of those, I would encourage some patience should you purchase one. Lenses like this have a learning curve, and you have to learn how to use a lens like this to its strengths and start to develop a feel for what situations it will and won’t thrive in.

But while a lens like this isn’t easy to use, modern autofocus makes it infinitely easier than it would have been. To be able to get 30FPS (or even 120FPS on the a9III) while tracking across the full sensor is a pretty unbelievable experience. I used to hate reviewing lenses like this because long focal lengths made it so hard to acquire a bird in flight, for example. Focus would hunt back and forth, and even assuming you eventually acquired focus, it would rarely be with the framing you sent out to capture. But yesterday I was looking at hundreds of geese out on the ice, none of whom seemed interested in flying, until out of the corner of my eye I saw one take off. I turned and immediately was able to grab focus (at 556mm), and every frame in the 138 burst that followed was in focus…starting from this, the very first one.

That means that there will be far more situations where a photographer can get both the focus and the framing they want, and end up with more of the moments like this (770mm, F8), where it is actually a shot that I’m proud of.

This is, frankly, pretty much the ugliest time of the year where I live. So if I can shots that I like with this lens NOW, it lets me know that photographers shooting at better times of year will be able to get shots that they love. And that makes the $2900 Sony FE 400-800mm F6.3-8 G OSS not only the first Sony zoom to reach 800mm, but also makes it probably the best zoom to hit 800mm.

Pros:

  • The first Sony zoom to reach 800mm
  • Beautiful build quality including robust weather sealing
  • Excellent handling (internal zoom helps balance)
  • Good feature set allows you to stay out of the menus
  • Incredible autofocus performance – quiet, fast, and accurate
  • Pair it with a Sony sports camera and get amazing tracking
  • Strong, consistent optical performance across the zoom range
  • Low vignette
  • Good contrast and chromatic aberration control
  • Can be used with Sony’s 1.4x and 2.0x TCs
  • Better optically than 200-600 + 1.4x at long ranges

Cons:

  • Slow maximum apertures mean that you’ll need good light
  • Stabilization is just okay
  • Big and heavy
  • Contrast at F8 isn’t exceptional
  • Slow maximum aperture limits applications

Yongnuo 56mm F1.4 DA DSM WL Pro Gallery

Dustin Abbott

March 27th, 2025

Yongnuo’s “Commander” series of lenses has thus far been consistently good. I’ve previously reviewed first an 11mm F1.8, then the first of the trio of faster primes at standard focal lengths. First came the 33mm F1.4, then the 23mm F1.4, and now we will cover the telephoto end of the equation in the new Yongnuo YN 56mm F1.4S DA DSM WL Pro. This series has come with a rich feature set, nice build, good autofocus, and quality optical performances. The YN 56mm delivers a full frame equivalent of 84mm, or roughly an 85mm lens on your Sony E (tested here), Nikon Z, or Fuji X-mount APS-C cameras and their 1.5x crop factor. Is the 56mm a worthy addition to this series and worth the asking price of about $275 USD? You can find out my full thoughts by watching the video review, reading the text review, or just enjoying the photos in the galleries below.

Thanks to Yongnuo for sending me a review sample of this lens. As always, this is a completely independent review. *The tests and most of the photos that I share as a part of my review cycle have been done with the APS-C mode (26MP) of my Sony a7RV camera.

__________________________________________________________________________________________________

Here’s a look at my reviews of this series of wirelessly connected lenses:

__________________________________________________________________________________________________

The 56mm (85mm) is a popular focal length because it sits as perhaps the most versatile focal length for portraits. It is long enough and fast enough to strongly blur out backgrounds, but not so long that it is difficult to work with in smaller spaces.

The 11mm F1.8 was the first of a new series of lenses from Yongnuo that they call the “Commander Series”, and this 56mm is part of a secondary trio of lenses of 23mm, 33mm, and 56mm F1.4 options that all share very similar design elements.

If you don’t speak Yongnuo, let me break down what those letters mean in the 56mm F1.4S DA DSM WL Pro lens designation. In many ways this follows the Fuji naming convention which puts a list of features right in the name.

  • S = Sony, or Sony E-mount
  • DA = APS-C
  • DSM = Digital Stepping Motor
  • WL = Wireless control
  • Pro = upscale build, additional features

The YN 56mm has a lot going for it, including a great focal length, great functionality, and fairly strong image quality.

Yongnuo YN 56mm F1.4S DA DSM WL Pro Review

Dustin Abbott

Here’s a look at my reviews of this series of wirelessly connected lenses:

__________________________________________________________________________________________________

The 56mm (85mm) is a popular focal length because it sits as perhaps the most versatile focal length for portraits. It is long enough and fast enough to strongly blur out backgrounds, but not so long that it is difficult to work with in smaller spaces.

Like many of these inexpensive 56mm lenses, the YN 56mm is sharp but can’t match a full frame 85mm lens when it comes to the quality of bokeh. Fuji’s expensive XF 56mm F1.2 WR (my review here) is the exception to that rule, but it isn’t inexpensive, either. And, while an F1.4 lens has the same light gathering potential whether it be an APS-C or full frame lens, the crop factor of APS-C does make for less shallow depth of field. The two shots below were taken about three hours apart (so somewhat different lighting), but it does illustrate how much more shallow the depth of field is for the full frame 85mm lens on the right though the magnification is actually higher for the YN 56mm lens on the left.

That being said, the Yongnuo is very capable of producing very shallow depth of field shots with highly blurred out backgrounds.

The YN 56mm (as we’ll call it for brevity) is a very feature rich lens, as we’ll see, but one of those innovations requires purchasing an inexpensive (under $25) remote control unit that leverages a 2.4gz wireless module built into the lens. Far from just being a basic remote control unit, this remote control allows you to remotely control focus, do aperture racking, set up A-B focus pulls, and more basic functions like take photos, start video, and do whatever you have the function button programmed to do. It’s a very clever little device particularly for video functions as you can do some of these key movements without touching the lens and introducing vibration.

The 11mm F1.8 was the first of a new series of lenses from Yongnuo that they call the “Commander Series”, and this 56mm is part of a secondary trio of lenses of 23mm, 33mm, and 56mm F1.4 options that all share very similar design elements.

If you don’t speak Yongnuo, let me break down what those letters mean in the 56mm F1.4S DA DSM WL Pro lens designation. In many ways this follows the Fuji naming convention which puts a list of features right in the name.

  • S = Sony, or Sony E-mount
  • DA = APS-C
  • DSM = Digital Stepping Motor
  • WL = Wireless control
  • Pro = upscale build, additional features

The YN 56mm has a lot going for it, including a great focal length, great functionality, and fairly strong image quality.

There are also a few weaknesses along with many strengths, and we will break down it all in our review.

Build and Handling

The 56mm focal length has seen a lot of releases over the past few years, including a variety of releases from both first party brands (Fuji) and the many third party brands on the market, like Sigma, Viltrox, Tokina, Sirui, and TTArtisan. The YN 56mm shows well in this class, however, with a very reasonable price and more features than almost all of the competing lenses. This does come at the cost of some weight, however, as the Yongnuo is fairly heavy at 368g (13.1oz) in the group. It has similar external dimensions to the 23mm and 33mm, but weighs just a bit more due to the larger glass elements in this longer focal length. Fuji’s own 56mm F1.2 WR lens is a fair bit heavier (445g), but it also has a faster maximum aperture. The YN 56mm is very similar in size to the recently released YN 23mm F1.4.

That visual similarity does change when you introduce the hoods, however, as the hood for the 56mm is considerably deeper.

Like the 33mm F1.4, the YN 23mm is 69mm in diameter (2.7″) x 87mm (3.4″) in length, which is about 13mm longer than the Fuji 56mm lens but the Fuji lens is considerably wider in diameter at 79.4mm. The front filter threads are a common 58mm size which is shared across the whole trio of new lenses from Yongnuo.

You’ll note the “Wi-Fi” radio signal logo next to the lens designation. Yongnuo continues to be the only company I know of utilizing this, though I have seen Bluetooth in a few Viltrox lenses.

While some competing lenses have an aperture ring, the Yongnuo adds several other features, including the ability to declick the aperture, a custom/function button, and a two mode-custom switch that allows you tweak the behavior of the ring.

As noted, this is a very feature rich little lens. We have a function/focus hold button on the left side of the barrel. That function can be assigned from within the camera.

There’s also a custom switch that allows for a few different functions. In one mode, it serves a an AF | MF switch, with mode I being AF while mode II will switch to MF.

The manual focus ring has a nice feel to it overall, though the weight is on the lighter side. There is no obvious stepping, however, so focus moves fairly smoothly when using the MF ring. You can program the custom switch to this function by turning the camera off, setting the position to II, and then holding the custom button down. Then power the camera back on, and you will feel a click in the lens.

To use the optional remote control, turn the camera off, set the switch position to I, and then hold down the function button while turning on the camera. Now position “I” will mean that wi-fi is turned on for remote communication while position “II” will mean that it is turned off. I would recommend keeping it in the off position when it is not in use. I haven’t noticed a battery drain issue, but you can essentially assure that this won’t be an issue by turning it off.

The YN 56mm also has a robust approach to aperture control. It has an aperture control ring with one third stop detents between F1.4 and F16 along with an automatic position that can be accessed past F16 (there is a firmer detent there to keep from accidental switches between the two). The feel of the clicks is good, with clear delineation of each position but without being rough.

There is also a declick option with a switch on the right side of the barrel. Click that switch and you can smoothly rack through the aperture, which is particularly useful for video work.

The aperture iris itself has 9 rounded blades to help ensure circular specular highlights when stopped down, though, in practice, this doesn’t work that well. Even by F2 you can clearly see the shape of the aperture blades in specular highlights (series has F1.4, F2, and F2.8).

The lens barrel is made of metal, and it has a nice, anodized black satin finish. The lens design is very clean and modern.

A deep petal-shaped lens hood is included. While it isn’t anything particularly special, it is sturdier than some and bayonets into place with a reasonably precise feel.

There is a USB-C port for firmware updates covered by a small rubber gasket. Be careful when pulling it out, as it is small and wouldn’t be hard to lose. It’s also nearly impossible to pry out unless you have a small prying tool, like a very small flat screwdriver.

The USB-C port will allow for quick and easy firmware updates, which is a smart move by Yongnuo considering that they are a third party lens maker, so they may have to rely on firmware updates to maintain compatibility with cameras in the future. The lens does include a USB-C cable in the box in case you don’t have one.

There is a metal lens mount with a weather sealing gasket attached. Yongnuo also claims a fluorine coating on the front element to resist fingerprints and moisture.

One area where the Fuji 56mm F1.2 and Sigma 56mm F1.4 have a clear advantage is in minimum focus distance. Those lenses can focus as closely as 50cm (producing a 0.14x level of magnification), but the YN 56mm can only focus as closely as 57.9cm. The Viltrox 56mm F1.7 splits the difference at 55cm, though it shares the maximum magnification figure of 0.11x, which looks like this:

In real world use, I would say that the magnification level, while not particularly high, is enough to allow you to really isolate subjects.

The remote control has a small LCD screen and is primarily controlled through the main knob that can be clicked to switch through various functions and rotated to control those functions. There are two buttons for programming A and B focus pulls (just set the focus position, hold down the corresponding button for one second, and either “A” or B” where appropriate will light up. There’s a power switch on the side and also a custom button on the side that corresponds to the custom button on the lens. Clicking it will enable whatever function is programmed to that button on the lens.

Using the remote isn’t always intuitive, but if you’ll spend a few minutes with the included user manual it becomes easy enough to use. Range is up to 30 meters, which definitely gives you some flexibility for controlling off camera.

The fact that the Yongnuo is both the cheapest ($268 USD) and most feature rich lens in the bunch of F1.2 and F1.4 options is pretty impressive, and that has given this whole series a unique advantage relative to other options. I’m not sure if Yongnuo’s market share is growing through these lenses, but it probably deserves to.

Autofocus and Video

Yongnuo has equipped this whole series, including the 56mm F1.4, with what they call a “digital stepping motor” (DSM). I’m not entirely sure how a digital stepping motor varies from a typical stepping motor, so I suspect this is mostly their own marketing language. Focus speed is pretty good, and I’ve gotten good accuracy even in narrow depth of field situations, like in the shot of this pigeon on the beach at F1.4:

You can see the precision of focus in this shot.

There is almost no noise to be heard even if I put my ear next to the lens barrel. There is the slightest buzz from the motor, but so quiet as to be nearly undetectable. Focus speed is good, too, with near instant transitions from one focus point to another either indoors or out. The fact that focus speed matches the other lenses in the series despite being a longer focal length is great for Yongnuo.

I found that real world precision was good, whether shooting human subjects, like this speaker in church.

…or when tracking animal subjects, including birds in flight.

For stills I’ve been impressed with the overall quality of focus with the lenses from this series. The fact that we’re getting such great autofocus from even smaller third party lensmakers like Yongnuo these days is impressive.

I tested focus for portraits at a variety of focus distances, and focus locked on immediately and accurately in all of them.

In my formal tracking test the Eye AF tracking box stayed locked onto the subject as I moved around throughout the frame. I suspect that most photographers should be happy with the focus accuracy and speed of the YN 56mm.

As with most third party lenses, if your goal is tracking fast action, you might want to go with a Sony lens (not that there are many in this focal range), but for most people in most situations, autofocus for stills was pretty great.

Video AF

On the video front I found mostly good results. Focus pulls were smooth with minimal steps, though I did see a tiny final adjustment at times. Focus breathing is more pronounced at this longer focal length than at the shorter ones.

The YN 56mm was mostly okay with my hand test where I alternately block and then remove the camera’s view of my face with my hand. Transitions were smooth, though I did find that I needed to keep my hand in place an extra beat or two before focus would transition to it. Reactiveness was a little slow.

Video footage was generally good, though fringing can be pretty obvious in certain situations. Here’s a freeze frame from one of my clips:

Focus seemed stable in my static shots and didn’t jump around. Overall I would call focus stable but not reactive, which is pretty consistent with what I’ve seen from this series of lenses.

Yongnuo 56mm F1.4 Image Quality Breakdown

The YN 56mm has an optical design of 10 elements in 9 groups. Half of these are exotic elements, including high refractive elements, low dispersion, and ultra low dispersion elements.

The MTF chart shows a fairly consistent result across the frame, with a few minor dips and rises. The F8 graph levels out some of the dips and rises, and it is one of the rare lenses where the corner performance (at least on the sagittal plane) is better than the center performance. This may be a budget lens, but that’s solid sharpness.

The biggest practical negative I saw was some fairly obvious fringing in certain situations. This showed up not only in transitions but also in some high contrast situations, like on this flying gull, cropped from a larger shot.

That fringing was very evident on my chart as well, so just be aware that this is probably the most significant optical issue with the YN 56mm. That green fringing in particular is quite obvious.

Lateral chromatic aberrations (LaCA) are much less of an issue, with only very minimal amount of fringing near the edges of the frame.

Often people are interested in the amount of coverage APS-C lenses provide on full frame cameras. This is not some kind of “stealth full frame lens”, as most of the additional full frame image circle is obscured by the “mechanical vignette” of the lens not covering the full frame portion of the lens.

There’s not enough additional coverage available to warrant using it on full frame and cropping. This is an APS-C lens, period. As is almost always the case, you would be better served by buying a full frame lens if you want full frame coverage.

There’s some obvious pincushion distortion, though it does correct in a linear fashion.

I used a -10 to correct the pincushion distortion, which is enough to be noticeable without correction, but vignette is fairly low, requiring just a +32 to correct, or about one stop.

So how about resolution and contrast? My tests have been done on a 26MP APS-C mode of my Sony a7RV. Here’s the test chart:

Here are F1.4 crops at roughly 200% from across the frame (center, mid-frame, and lower right corner).

That’s good sharpness, though there are a number of existing 56mm lenses that could match that, including the Sigma, Viltrox 56mm F1.7, and the aforementioned Fuji.

Still, there’s a solid amount of detail, though you can see some fringing in the high contrast light.

In lower contrast situations I felt like the detail looked more compelling.

Stopping down to F1.8 makes relatively little change (a bit more contrast), with a little more obvious contrast at F2.

This crop from a portrait shot at F1.8 shows good detail; I suspect most would be happy with that level of detail.

By 2.8 I see a good performance right off into the corners.

You’ll see a bit more improvement as you stop down into the prime landscape apertures like F5.6-F8:

That means that the YN 56mm is a very nice landscape lens, providing good detail and contrast across the frame.

Here’s another shot that shows the solid detail across the frame.

Sharpness peaks around F5.6, with F8 being very close to the same. I’ll show the other corner now, which also demonstrates a good quality of centering in the lens that I tested.

Diffraction will start to soften the image after that, with a mild amount at F11 but a more obvious amount by F16. Diffraction isn’t as obvious at the 26MP level on Sony, but expect this to be more pronounced if you are using a Fuji 40MP sensor.

Thus far the only 56mm that I’ve really been wowed by when it comes to bokeh rendering is the Fuji 56mm F1.2 WR, but in the right scenario I think the bokeh is pretty good from the YN 56mm.

I don’t consider the “right situation” to be one with prominent specular highlights, however, because there is a fair bit of fringing in those highlights.

This image is a good example of two sets of strengths for the lens. first of all, the quality of the blur of this rather complicated background is good.

But secondly, the real world sharpness at F1.4 is great.

Flare resistance is mostly good. I had no flare related issues shooting into this bright rising sun over the Atlantic.

This shot that puts the sun up in the corner is a little more impacted, however.

Overall I think this is a pretty average performance.

Yongnuo’s optical glass is fairly good but not top notch. Colors were mostly good, however, though not quite as special as what you’ll get from higher end lenses.

But it’s important to remember that this is a lens that costs under $270. I would say that the overall rendering is pretty great for the money. When compared to other lenses in this price class I think the optics are competitive and the feature set is clearly much more robust than what competing lenses offer. If you’d like to see more image samples, check out the image gallery here.

Conclusion

The Yongnuo 56mm F1.4S DA DSM WL Pro is a pretty attractive option if you’re looking for a 85mm equivalent lens on your APS-C camera. It is a feature rich, focuses well, has weather sealing, and delivers a pretty strong optical performance, too. The price is more similar to an F1.8 lens than an F1.4 lens, which doesn’t hurt, either.

It is priced as a mid-tier lens, but it probably outperforms that. The Sigma 56mm F1.4 DN stands as perhaps a superior lens optically, though far less feature rich, while the Viltrox AF 56mm F1.7 AIR is the budget competitor that has fewer features but every bit as good of optics…and costs nearly $100 less.

But if you want a lens that has the features and the performance, it’s hard to criticize the Yongnuo YN 56mm F1.4 DA DSM WL Pro. It does a lot of things well, and, outside of more fringing than what I would like, doesn’t really have any crippling optical flaws. If you are looking for this particular focal length, the Yongnuo YN 56mm F1.4 well worth consideration.

Pros:

  • Nice looking lens with nice build
  • USB-C port for firmware updates
  • Good manual focus ring and experience
  • Very feature rich
  • Weather sealed
  • Declickable aperture
  • Wireless remote control
  • Custom button
  • Autofocus motor is quiet and fast
  • Good sharpness wide open
  • Excellent sharpness stopped down
  • Fairly good bokeh
  • Great price to performance ratio

Cons:

  • Some fringing issues
  • Gasket for USB-C is hard to remove and easy to lose
  • Low magnification

Bluetti Elite 200 V2 Portable Power Station Review

Dustin Abbott

March 24th, 2025

I’ve done about ten different Bluetti reviews along with many other power stations over the years, and most of them try to sell you on some kind of uniquely marketable feature.  The Elite 200 V2 has very few marketable features – no special ports (or number of ports), battery swapping or expansion, or other gimmicks…but what it does have is serious storage and power output.  The Elite 200 V2 isn’t sexy…but it sure is practical! It’s the most powerful portable unit I’ve tested, and with a 2073.6Wh, it’s also got more battery capacity. The Elite 200 V2 is going to be a serious asset for camping, overlanding, and backup situations. For my full thoughts, check out the video review below or read through my review notes I’ll share here.

Viltrox AF 135mm F1.8 LAB Z-mount Gallery

Dustin Abbott

March 19th, 2025

In the fall of the 2024 I had the opportunity to review the long awaited first entry in Viltrox’s Premium LAB series – the Viltrox AF 135mm F1.8 LAB FE. I loved the lens on Sony despite it being large and heavy and gave it a pretty glowing review. One regret I had was that my Megadap ETZ221 Pro adapter didn’t play well with the LAB 135mm, so I didn’t have a chance to use the Sony FE version on my Nikon Z8. As an aside, I’m interested in seeing if Viltrox’s own new E to Z adapter solves that problem. But fortunately we have a better solution, because a new Nikon Z mount version of this amazing lenses has officially arrived, and frankly the big LAB is going to be a better match for my large Nikon Z8 body anyway! One thing hasn’t changed; this is still a big, heavy lens, but it also a very serious challenger to the premium Nikkor Z 135mm F1.8 S Plena…particularly considering that lens’ hefty $2500 USD price tag. The Viltrox AF 135mm F1.8 LAB Z is an optical juggernaut, and the bargain price tag of $899 USD makes it a huge value (and if you use code DUSTINABBOTT at checkout at Viltrox, you can get an additional 5% off!). Find out if this should be the 135mm in your own kit by watching the video review, reading the text review, or by just enjoying the photos from the lens in the galleries below.

Viltrox AF 135mm F1.8 LAB Z Review

__________________________________________________________________________________________________

I’ve had a long-term love affair with 135mm lenses. I still own some classic 135mm options from the film era (SMC Takumars and the like) and have been privileged to own some of the modern premium 135mm options, from the Canon 135mm F2L to the Zeiss Milvus 135mm F2 to the Sony FE 135mm F1.8 G Master. In short, I have owned a premium quality 135mm for just about as long as I have been a professional photographer. I value the focal length above all for the utterly unique portrait shots you can get; shots the feature extreme isolation and wonderfully creamy bokeh. There are many lenses where you can get a blurred out background if you get very close to your subject, but a lens like the LAB 135Z allows you to completely isolate your subject even when you are a much further distance away, like this:

And look at what happens if you take a tighter crop of that shot:

You can perhaps get a sense of just how exquisite the combination of bokeh and sharpness is…even at F1.8.

I love the look of images shot with a fast 135mm lens…but I don’t end up shooting with the focal length as often as I might like. My least favorite part of owning premium 135mm lenses is how comparatively rarely that I reach for the lens (just too long for a lot of situations). For me that has made me question the amount of money I have sitting on the shelf far too often, and has caused me to (at times) sell such a lens to help fund a more practical purpose. The size and weight of the LAB 135Z might still be such a deterrent, but the price won’t be. I would feel far less qualms over a $900 (or less!) lens sitting on the shelf a bit too much than having a $2500 lens like the Plena sitting on the shelf.

The Viltrox AF 135mm F1.8 LAB Z is a fiercely good lens, and I suspect is going to be somewhat disruptive here on Nikon because of just how good it is at such an inexpensive price.

*There will be some redundancy with my Sony FE review of the lens as this is in essence the same lens mechanically, cosmetically, and optically. I have updated the imagery and also any area of unique performance to the Nikon platform.

Viltrox LAB 135mm Build and Handling

There is basically one variance from the E-mount version of the lens to the Z-mount version of the lens, and that is that the barrel of the lens near the mount is much wider on the Z-mount version to accommodate the significantly wider diameter of Z-mount (on the right).

You might also notice that the rear weather sealing gasket is a little more obvious on the E-mount version, but that is only because the gasket is seated a little differently to accommodate the different mounting position on Nikon. Other than that the E-mount and Z-mount versions are essentially identical, with similar size, length, and features.

In many ways the new LAB 135mm feels like a blend between a Canon L series and a Zeiss Batis lens. The overall feel of the lens and its textures reminds me of a Canon L series, while the top mounted LCD screen reminds me of a Batis lens.

Nikkor 135mm Plena is a big lens, as have been all of Nikkor’s premium fast primes. It is 98mm (3.9″) in diameter and 139.5mm (5.5″) in length. It weighs 995g (35oz). But the LAB 135Z manages to top that. It is 93mm in diameter (3.66″), a little narrower, but is a bit longer at 147.6mm (5.74″) in length. That’s not bigger (the Plena has an internal volume about 1% higher), but the LAB 135Z is a hefty lens, weighing in at a whopping 1268g (44.72oz), or about 270g more than the Plena (I weigh the FE version of the LAB at 1236g, a little lighter due to that smaller diameter near the lens mount). Do not buy this lens if you are adverse to some weight. Why is it so heavy? Above all, it has a LOT of glass inside.

Up front we get a large 82mm front filter thread, though that is pretty common for any 135mm lens with an F1.8 aperture. You can’t beat physics!

Viltrox has demonstrated that they are capable of producing small, lightweight lenses with good optics (the AIR series is a perfect example of that), but that’s not the point of the LAB series. The LAB series seems to following a similar design philosophy to Nikon’s F1.2 S line lenses: build the best optical instrument at the focal length that you can, and don’t worry about the size and weight. These types of lenses are not for everyone, but some photographers simply want the best. Those types of photographers are going to be delighted with the LAB lenses.

It looks like Viltrox’s Pro Series will take a more traditional approach to aperture similar to either Sony’s GM series or Sigma’s better DN prime lenses, namely a marked aperture ring that could either be clicked or declicked. Their approach with the LAB series is a little more similar to Nikon’s approach with the S-line lenses. The aperture ring is a bit more like a command dial that interacts with the LCD screen than a traditional aperture ring with hard stops at either end. You still have the option to have the ring either clicked or declicked, but the aperture rings seems to move in a speed dependent, non-linear way. A quick rotation will speed you through the aperture options, while a very slow rotation doesn’t even move a one-third stop with each click. The LCD screen shows only one third stops between the full stops like F2 and F2.8, so I’m not sure what the point of this is. A more traditional aperture control setup would have been preferable all around, though, like Nikon Z mount lenses in general, you can use this ring for other things than aperture (exposure compensation, ISO, etc…).

Unlike native Nikon lenses, however, you do have the option to have the aperture clicked or declicked via a switch on the left side of the barrel.

When you turn the clicks off you can smoothly move through the whole aperture range without defined slots.  This allows for smooth video aperture racking and has become an expected pro-grade feature on modern lenses. There does seem to be less lag in the aperture iris than many lenses, however, making smooth aperture racks more possible. This is the rarely lens that I prefer the aperture clickless rather than clicked even for stills.

Unlike Sony (at least at the present), some of Nikon’s cameras have a top mounted LCD screen, and while you can see the selected aperture on both screens, you can see that it is larger and more easily seen on the camera rather than the lens LED.

The iris itself has 11 aperture blades, and these make for a nicely rounded aperture even when stopped down a fair bit.

Beneath the declick button there is a three position focus limiter that allows you to select the full range, up close (0.7-2m), and to eliminate the close focus range (1.5m to infinity). The LCD screen also functions as a distance scale, showing you the focus distance in large letters while showing a scale above in smaller letters.

Further up the barrel is an AF | MF switch along with two FN (function) buttons.  The top one functions like the typical function button, performing whatever function you have that button programmed to in camera.  The second button is going to be used more commonly for video functions, however, as when in manual focus mode it allows you to preset two focus positions and automatically switch between the two at the press of the button (A-B focus).  This works in conjunction with the LCD screen on the top of the lens (more on that in a moment).  You can preset the focus position(s) by long pressing the FN 2 button, and then access the focus changes by short pressing it. 

Now to that LCD screen.  The LCD functions in many ways like those found on the Zeiss Batis lenses, though with some improvements.  The screen itself is nice and bright, allowing for good visibility even in bright conditions.  It solves the problem of a distance scale (something missing on most mirrorless lenses), as it gives you a large font telling you the precise focus distance along with a distance scale above that.  The bottom part of the screen gives you a readout of the current aperture.  It also gives you some information related to the function buttons however, with the Fn icon lighting up when the first Function Button is depressed, and then the A or B function lights up when you are presetting focus distances.    There’s actually a lot of useful information on the LCD screen once you get familiar with how it is all being displayed, though I’m sure a lot of people will still find it somewhat of a gimmick.

The manual focus ring is slightly raised and has a rubberized, ribbed texture.  It moves fairly smoothly, I feel like there is a little more feeling of steps or pulses from the focus motor while manually focusing than on Sony. There’s obviously a bit of a difference with the way that input on the focus ring is routed through the Nikon body, as on Sony the focus process feels smooth and linear. Like the aperture ring, input on the focus ring seems to be speed specific and not quite linear. Using the A/B focus is a much more precise way to set up repeatable focus pulls.

We also have weather sealing on this lens that starts with a unique maroon-colored gasket at the lens mount along with other seal points through the lens (a total of 12 of them, by my count).

This is an internally focusing lens, so there is nothing that moves where dust might intrude. There’s also an HD-Nano multilayer coating on the front element to help with water and fingerprint resistance, making the front element easier to clean.  As always, however, “moisture-proof” does not mean “water-proof”, so don’t go crazy! This is, however, a professional grade lens with professional sealing.

Viltrox continues with a trend that other lens makers are now imitating by including a USB-C port in the lens mount that allows you to do firmware updates right to the lens.  I’m a fan of this approach, as it eliminates the need for a separate dock or lens station for firmware updates, and I find the process a little more intuitive than even doing firmware updates through the camera.  This allows Viltrox to future proof their lenses and continue to improve them through firmware.

As with other recent Viltrox lenses, the lens is Bluetooth equipped, which means that you can use the Viltrox app for IOS or Android and update firmware wirelessly. You can also program a custom splash animation to the powerup cycle on the lens (I’ve got mine showing my business logo during startup).

There is no lens based stabilization, so you will need to rely upon the in-camera stabilization if your camera is so equipped.

One thing worth noting is that when the lens is powered off, there will be some movement/clunking if you rotate the lens up and down. This can be very disturbing if you are not familiar with modern lens design. Many high end modern lenses employ floating elements that allow for better up close performance. The lens groups are not fixed, but float in a certain area, so when they are not energized they will move around a bit. This is by design, however, and when the camera is powered on, those elements will be energized and become fixed. You can rotate the lens up and down without anything moving around. It feels like the Viltrox has finetuned this process with the LAB 135Z, however, and it seems a bit less obvious than on the Sony version.

The benefit of this design is that you get a much better up close performance that you typically see on Viltrox lenses. You can focus as closely as 72cm, giving a maximum magnification figure of 1:4, or 0.25x, which bests the 0.20x (1:5) available on the Plena. Up close performance is fantastic even at F1.8, with excellent sharpness and contrast and a nicely flat plane of focus.

I used the LAB 135Z for some product shots for another review, and it delivered excellent results.

That’s macro lens levels of performance there!

Viltrox has redesigned the front lens cap with a bevel along the front that makes it feel slimmer (good, as this is their biggest front lens cap so far). The lens also comes with the hood and a nicer than usual leather pouch (similar to Canon L-series lenses). There is some cushion on the bottom, but I don’t find these pouches nearly as useful as a good padded nylon case like what Sigma provides.

The LAB 135Z comes with the nicest lens hood that I’ve seen on a Viltrox lens. The plastics are extra thick and sturdy. There is a felt lining inside to keep light from bouncing around, and there is a rubberized transition section that helps to protect the lens from bumps and also makes a nice option for placing the lens facing down. The lens doesn’t have a lock, but does have a firm bayonet into place that sits securely. I had no issues with it coming loose. I will note that it can reversed for storage but fits very tightly, so it can be a little work to get off sometimes as the rubber of the hood grips the rubber of the focus ring.

As noted, the lens barrel construction reminds me a lot of Canon’s better L- series lenses, with an magnesium alloy body, which is the same material used in expensive camera bodies. The new LAB badge on the side of the barrel reminds you that this is from this new premium series of lenses.

While I don’t agree with all of the ergonomic choices Viltrox made with the LAB 135mm, I do think that this is a very nicely executed package.  The lens feels high quality in the hands, and it handles like a premium lens. In many ways this feels like a much more expensive lens than the $899 USD price tag. The finish feels durable and I would expect the lens to hold up well for the long haul. This is a big, heavy lens, so that will obviously be a deterrent for some buyers, though frankly the Plena is actually a bit bigger (though the LAB is heavier). Sony does have the slightly smaller, lighter option in the form of the Samyang AF 135mm F1.8, but at the moment, Nikon has no such option. I will say this as a final word on the matter: the LAB 135mm feels like a much more natural fit on a beefy body like my Z8 than it does on any of my smaller, lighter Sony bodies. I’m not sure that “two wrongs make a right” applies here, but perhaps we could say that a heavy lens makes more sense on a big, robust camera.

Autofocus (Stills)

I was excited to see that Viltrox was pioneering a new autofocus system with the launch of the LAB series, as I felt like A) they had gotten about as much out of their STM motors as they were going to get and B) a premium lens like this with big, heavy glass elements needs as much thrust in the focus motor as possible. Like the Sony FE version, the LAB 135Z is equipped with not one VCM (voice-coil motor), but dual “Hyper VCM” motors that work in harmony to drive autofocus. This is a similar approach to what Nikon has done with the 135mm Plena, and the dual high performance focus motors allow you to broaden the scope of what can be done with a fast prime lens like this, up to and including sports.

As with the FE version, I have been reviewing a prerelease copy of the LAB 135Z, so the lens arrived without the final “retail firmware” update. But you could also tell that they’ve had that extra six months to refine focus, as the Z-mount version just felt more confident out of the box (the Sony version got there after a firmware update). Fortunately firmware updates are pretty simple, and can be done via a drag and drop on a computer, or via Bluetooth through the Viltrox app.

Autofocus speed is very good. Not quite instant, but near to it. In my formal tests I saw quick and mostly confident focus changes from close to distant. If I go back and compare my results to the Sony FE version, I find that focus is a little slower and perhaps a little less confident. On Sony the progressions from close to distant and back were nearly instant and with complete confidence, but I find a few more little pulses and an occasional quick rack in the wrong direction. In real world shots, however, focus changes tend to be smaller and I didn’t really notice the same things.

That included shooting in lower light conditions. You can shoot with precision even in situations with a tiny depth of field, like this:

I’ve been playing a lot of squash recently, and I was curious to see if the AF speed was sufficient to keep up with the rapid fire action on the squash court. I tested the Sony FE version with basketball, and it did fine, so this was something different. The good news is that focus had no problem keeping up with the action and acquiring subjects.

This is too long a focal length for this application, really, and you have to contend with shooting through glass (I would NOT want to be in there with a camera!), so I wouldn’t choose this combination for serious tracking of the sport. But that wasn’t really the point; I wanted to know if the lens could keep up on my Z8, and the easy answer was yes.

I actually feel like Viltrox has done a really solid job of porting over to Nikon’s focus algorithms here, as the lens feels very natural and at home on the platform. I’ve consistently been impressed with how well third party lenses that I’ve reviewed on other platforms first behave on Nikon. Often the VR (In Body Image Stabilization) works better, focus is very similar to what I find on Sony, and when testing on Sony, I ran into the typical limitation for all third party lenses: burst rates are capped at 15FPS for non-Sony lenses. Fortunately no such limitation exists on Nikon, so I was able to shoot as quickly as 30FPS and got consistent focus in those very quick bursts.

Someone next to me while I was shooting asked, “How many photos did you just take?” after one such burst. I told them I had no idea; all I knew is that I was getting 30 of them every second!

Focus precision was also exceptionally good. I had no problem nailing quick shots of Nala as she rolled around in a shaft of sunlight. Look at just how gorgeous the focus (and the detail!) is in this shot:

Focus sound is near silent, with a very light whirring sound as focus moves back and forth. There’s no drama associated with focus, just quick, accurate results.

Things were mostly fantastic when shooting portraits. I was literally shooting in the middle of a blizzard, and the sheer number of keepers despite the persistent distractions was actually pretty impressive.

A few times, however, the focus system got distracted by the snowflakes and it was like it couldn’t see past them to the subject, like here:

I ended up saving this shot anyway because I kind of liked the effect. The potential for these focus issues seemed to go away when I got closer, and the contrast of the subject become more obvious. My keeper rate for the portrait session was very high despite the conditions.

This is definitely in the upper tier of autofocus performance for third party lenses. It’s amazing how far Viltrox has come in just a few short years.

Autofocus (Video)

Video autofocus was largely an extension of what I saw from my stills tests, though the flaws were a little more obvious. The hint of little focus racks in the wrong direction were more obvious with video autofocus pulls, and everything didn’t seem quite as confident as I saw on Sony…though there is some hopes that the retail firmware could improve that.

Movement towards the camera was fairly good if the movement was consistent and linear, but if I stepped in and out of frame, the reactiveness of picking me back up had some lag.

Video focus on real subjects seemed to be fine. Here’s a screenshot from some 4K60 footage during the portrait shoot.

Video footage looks noticeably very detailed and crisp, and the beautiful color, contrast, and rendering of the lens makes for some gorgeous footage.

Viltrox clearly wanted the LAB series to be a statement in every area, and fortunately that includes autofocus. While autofocus isn’t quite as exceptional on Nikon as it was on Sony, it’s also true that Sony’s focus is a little more sophisticated in general. I was very happy overall with focus performance here.

Image Quality Breakdown

Ahhh, and now to my favorite part, because the LAB 135Z is just a special, special lens. I fell in love with the Zeiss Otus lenses because, despite their being ridiculously big and expensive, they were just so good optically. It might be heresy to say, but the Viltrox AF 135mm F1.8 LAB is just that kind of lens. The optical design is 14 elements in 9 groups, with four of those being ED (low dispersion) elements and two of them being HD (high refractive index) lenses. The MTF is fantastic, with an absolutely stunning center and midframe performance that isn’t quite the same in the corners. At F8 the MTF is pretty much a straight line across the top, i.e. perfect.

Just for fun, let’s take a look at the Nikkor 135mm F1.8 Plena MTF:

Gulp. If the MTF is to be believed, the $900 LAB 135Z is sharper all across the frame than the $2500 Plena.

And yes, if we look at real world images, the results are just ridiculously sharp.

Take a look at the crop:

In fact, the Viltrox LAB 135mm F1.8 delivered once of the best all-round optical performances that I’ve ever seen and is essentially strong to extremely strong in all areas that I test. It is the rare lens that is both technically and artistically excellent. Look at the lovely overall rendering from this image:

And now let’s look at the crop that shows the technical excellence:

Yup. That’s great.

More on this in a moment. Let’s look at the technical side of things.

I was expecting a lens well corrected for LoCA (longitudinal chromatic aberrations), and that is the case here. I see mostly neutral results on either side of the plane of focus without any visible fringing.

I tried a wide variety of situations to see if I could find some fringing while testing both the Sony and Nikon versions of the LAB 135mm, but the LAB beat me. Look at how utterly neutral it is when dealing with the shiny and engraved bits of my classic lenses, which are typically amongst the absolute worst case scenario for fringing.

Brilliant.

LaCA (lateral chromatic aberrations) typically show up along the edges of the frame with high contrast transition points.  I saw a small amount of LaCA in my tests, which actually surprised me, as I didn’t see any on the Sony version.

Viltrox lenses have not always had great profile support, and if there is any advantage to this it is that they have gotten accustomed to doing a lot of the corrections optically rather than relying on software corrections. On the Sony FE version I found essentially no distortion or vignette. Essentially all the lenses I’ve tested first on Sony and then on Nikon have exhibited more vignette on the Z-mount version.

That’s the case here as well. There’s still no measurable distortion (there’s maybe a fraction of a percent of pincushion), but I do see some vignette (I used a +50 in the correction above).

It’s not a big deal and easily correctable.

We’ll move on to inspecting our test chart.  This test has been done on a 45MP Nikon Z8 sensor.  I use a high end tripod and two second camera delay to ensure vibration doesn’t affect images.  Here’s a look at the test chart that we will examine at high magnification:

If we take a look at crops (at 200%) at F1.8 from the center, mid-frame, and lower right corner, we find that center and mid-frame performance is exceptionally good, and that sharpness extends right to the corners.

The lower resolution point on Nikon (45 vs 61MP) only makes the results look even more consistent. If I compare mid-frame result above with the upper left corner from the (both at F1.8).

Yes, you can see that the mid-frame result is slightly sharper, but that is remarkably consistent performance.

To put that in context, let’s take a look at the same result using the Nikkor Z 50mm F1.4 that released in 2024. Not a top tier lens, obviously, but a pretty decent one that I gave a positive review to and even purchased for myself.

Wow! You can see just how radically sharper the LAB 135mm is. This is definitely the sharpest lens I’ve tested on my Z8 thus far. Stopping down to F2 does make a mild difference, particularly in the outer parts of the frame, though you might be hard pressed to spot the differences without the two images side by side and at very high levels of magnification.

By F2.8 the sharpness levels are essentially at the ridiculous level. There are more fine details visible in this old two dollar bill than I knew were even there.

The eagle-eyed among you may notice a minor reporting bug that hadn’t been squashed in my pre-release firmware yet, namely that while the lens properly registers in Lightroom as the Viltrox AF 135/1.8 LAB Z, the focal length registers as 16mm. That bug will be dealt with in the retail firmware.

Stopping on down produces improvements so minor as to be hard to see most places in the frame, though I could tell the improvements in the far corners.

Physics will affect even the mightiest of lenses, however, so expect diffraction to start to soften the image by F11 and more obviously by F16, which is minimum aperture (though this lens is still sharper than many lenses at its weakest!)

You’ll have all the portrait sharpness you’ll ever need, with perfect amounts of sharpness and contrast and beautiful skin tones.

In fact, one of the best applications for a lens like this is to shoot environmental portraiture at F1.8, where you can shoot at longer distance, compress the scene, but still get a nice separation of your subject from the background.

This is a lens that is pretty obviously overengineered for the full frame image circle. I’d actually be curious if Viltrox would ever consider bringing the LAB series to the Fujifilm GFX platform and to see how well they would cover that larger image circle. I noted, for example, when reviewing the Sony version that the LAB 135mm consistently metered a little faster than the Samyang in my comparisons while delivering similar brightness levels, so I also believe that the T-stop is about one third stop faster than the Samyang. I wouldn’t at all be surprised to find that the LAB’s T-stop is very similar to its F-stop.

The Viltrox LAB 135Z clearly delivers near APO levels of sharpness and contrast. What is rarer still is the lens that can deliver incredible sharpness and contrast while also delivering soft bokeh…and you probably won’t be surprised to hear that this is one of them.

First of all, it does very well with specular highlights. Here’s an F1.8 image that shows that there is some geometric deformation near the edges of the frame, but overall the bokeh looks great. You can see just how big and soft the bokeh can be when you’re close to your subject.

If you really want all round specular highlights, stop down even to F2.5, and it is nearly perfect there.

But perhaps my favorite application is for portraits. First of all, the general rendering looks great.

But what’s harder to see when viewed full is how all of those different layers of snowflakes are being turned to varying sizes of specular highlights. It’s really pretty stunning.

The general rendering is just fantastic.

In the early stages of Viltrox’s lens development their optical glass was, well, more budget oriented, but that has radically changed in the past couple of years. I find Viltrox’s current optical glass to be excellent, and it also tends to be very neutral. Colors are rich, but not oversaturated. The images are neither warm nor cool, allowing you to choose your preference either in camera with the white balance or in post.

That intense contrast just makes the colors look very rich and, well, expensive.

Flare resistance was also very good on the LAB 135Z. The lens hood isn’t necessarily small, but it is smaller than many other 135mm lenses that I’ve tested because frankly it isn’t overly needed. Here’s a variety of positions and apertures shooting into very bright sun and you can see that contrast holds up fine, without ghosting or veiling.

I did test for coma on the Sony version, which I’ll share here (snowstorms don’t make for good astro tests!). This makes yet another interesting application for this lens, as the longer focal length lends itself to a different perspective on astrophotography. Coma was very well controlled even into the corners, and the extremely low fringing assures that bright heavenly bodies aren’t ruined by some nasty color smears around them.

The bottom line is that this is one the most complete lenses that I’ve tested optically, and I would be hard pressed to point to a better optical performance from any lens priced under $1000, and could probably count the number of better optical performances, period, on one hand.

Conclusion

I found reviewing the FE version the Viltrox AF 135mm F1.8 LAB a real treat, and I felt no differently about covering the Z mount version. To do my job correctly I need to invest a lot of time and care into using and evaluating a lens whether I personally enjoy it or not. It can be very frustrating to have a camera in hand in a beautiful photographic opportunity and be stuck with a lousy lens attached to the camera because that’s what I happen to be testing. Not so with the LAB 135Z; this is a lens that I would choose to shoot with. It’s also a fabulous match for my Z8 in the larger size of the camera, the great autofocus system, the stellar VR, and of course the gorgeous images that the LAB/Z8 combo can produce.

I’m so glad that Nikon has opened up to third party brands, and while this lens will certainly steal some potential Plena purchases, the availability of high end, affordable lenses like the Viltrox LAB series has the potential to sway customers debating between Canon and Nikon in Nikon’s direction.

I’ve come out this review impressed all over again. I recognize that LAB 135Z will be too big and heavy for some potential buyers, but if this happens to be something that you can look past, you will find an absolutely stunning lens that will produces images that are richer, sharper, and more compelling that what you can get with just about anything else in your bag. Yes, please!
