Hi, I'm Dustin Abbott. Over the last several weeks I've had to bite my tongue because some of you have asked the question that I've often heard, and that is when is there going to be a less expensive alternative to the very expensive Sony 100-400mm G Master lens for Sony mirrorless
0:28
Well, the answer is today, right now, because the Sigma 100-400mm F5-6.3 DG DNOS lens
0:38
has been announced for Sony and Leica, and I've been playing with one for the last several weeks
0:45
putting it through the paces, and I'm here today to give you my definitive review
0:48
of this very exciting new lens. Now, of course, the 100-400mm focal length
0:54
remains a very popular one for the simple reason that it's about the last bit of focal range like this
1:02
that can get you out to 400 millimeters that can still be done competently in a compact package
1:08
As a byproduct, you know, it's basically the size of a 70 to 200 millimeter f2.8 zoom
1:14
And so it's manageable for most photographers. It fits more easier easily
1:18
into most camera bags and carrying systems, but still gives you a fair amount of reach
1:24
and can be useful for wildlife, birding, sports, etc. And so, of course, while the 100-400mm GM lens has certainly been on a lot of photographers' wish list
1:35
its price tag of nearly $2,500 has put it outside of the reach of many photographers
1:42
So I'm sure you would be delighted to understand that this Sigma will come
1:47
and it will cost you less than $1,000 and will give you a lot of the performance
1:53
and image quality of the GM lens. How much so? Well, that's what we're here to determine
2:00
So if you prefer your reviews to be shorter and more to the point
2:04
then I recommend that you watch the standard review, and you can access that at this link here
2:10
Today, however, we're going to jump in in detail, draw some comparisons
2:14
show you some photos, do a lot of that work, and help you to draw a conclusion as to whether or not the new Sigma is for you
2:22
We're going to start by going hands-on and giving you a close look at this lens, its features, its handling, its build
2:29
Let's jump in and let's take a look. So we'll look a little bit closer here. First of all, you can see there is a mix of materials that makes this actually a nicer built lens than your standard contemporary lens
2:40
which is, again, kind of a meaningless designation. But they tend to be a little less well-made than either the art or the sport series
2:48
In this case, I'm not sure that that is true. The original frame here is made out of a magnesium alloy, and so very, very tough, obviously
2:56
Same material that cameras are built out of. Here you also have a brass mount, and so a really secure mount, which is kind of a Sigma trait
3:05
I will also note that there is a nice thick gasket here, which is actually surprisingly thick for a Sony lens
3:12
and so a little more robust there. At the same time, I don't see language from Sigma designating other seal points inside
3:18
and so maybe they're there, maybe they're not. I suspect if they were, they would mention that
3:22
So most of the moisture resistance and dust resistance is concentrated at the lens mount
3:27
Now, I will note that there is enough width here and depth for use with teleconverters
3:34
and in fact, for Leica, there are both a 1.4x and 2x teleconverter being announced alongside this
3:41
lens. Nothing yet for Sony, and so hopefully we'll see Sigma release something like that in the
3:47
future. I do suspect while I don't have one on hand that there is probably room for a Sony TC to fit
3:54
in there, but we'll find out after I've been able to test. And I will pin a comment down below
3:59
letting you know whether or not that works after my contact at Sony gives a little test
4:05
Now moving on from here, first of all, I want to note the way that the lens ships
4:09
ships without the tripod collar. And so what you've got here is actually a rubber sleeve that
4:14
fits over covering the screw heads it says 100 to 400 on here. So part of the reason why this
4:22
whole section is reimbursed in a higher grade material is that it is designed fortunately for
4:27
use with a tripod foot and in fact in this case it is the same tripod collar that ships with the
4:36
Sigma 105mm f1.4 art series lens. And so you have got a, you know, a fairly standard, effective
4:45
tripod collar here, does all the typical stuff. You can rotate and lock at any point. There are
4:50
some, you know, markings at cardinal points to allow you to line that up. Tripod foot is Arca
4:57
Swiss compatible, which I really, really love when that is the case. Nicely made. It'll give you about
5:04
123 extra grams of weight on the lens if you elect to use it. Now one advantage versus either
5:12
the Sony or in this case I've got the Canon that's standing in as a substitute since that's what I
5:17
own is that their tripod foot is removable. The collar is fixed and permanent. So it does mean
5:24
that you have the option here of you know having a little bit less weight if you tend to use it
5:30
handheld. And of course, you can elect whether or not you want the additional expense for that
5:35
tripod collar itself. If you don't, of course, you're free to use the lens handheld and to
5:41
just utilize this rubberized sleeve that they've given you to cover up those screw heads
5:48
And if you, you know, sit, seat it there properly, it looks pretty seamless. Looks like it belongs
5:53
there. Now, the rest of the material is a mix of some metals and, you know, nice, great engineered
6:00
plastics. I don't really have any complaints about the build. It's not as robust as what the GM lens
6:06
is, but neither is this a cheaply made lens. The focus ring is the next thing that you come to
6:12
It's actually nicely damped and very quality feeling, nicely executed. There is a bank of
6:18
switches here. And so for the most part, we've got everything we've got on the GM AF-MF switch
6:24
We've got a three position focus limiter. We have got a focus hold button and we have got a two
6:31
position OS standard mode and then two for panning or you can turn it off. And of course, great to
6:38
have an optical stabilizer here in the lens itself. And it's rated at about four stops. So not at the
6:45
top of the class, but certainly a useful amount of additional assistance. One area where we do
6:51
distinguish that while it has the focus hold button, the GM has that at three of the cardinal
6:56
positions to make it more accessible, but at least it is here. You also have a focus lock
7:03
The Sony lens actually utilizes, like the Canon, utilizes the tension ring to where you either
7:10
loosen or tighten rather than a focus lock Advantage of the tension ring is that you can implement that at any kind of zoom position So if I wanted it at 300 millimeters I now locked around 300 millimeters
7:25
The Sigma will only lock at the 100 millimeter position, and it will not lock at any other position
7:32
However, one other nice feature that we do have here is that this lens is purposely designed
7:38
around having the option of being both a twist zoom, the zoom action, although there's a lot
7:43
of barrel extension. It moves nice and smoothly, no wobble or play there. But you'll see that there
7:49
is a texturized portion here on the lens hood. It is designed so you can also use the lens as a push
7:55
pull design. And so a lot of people that have used 100 to 400 millimeters, they actually prefer
8:00
a push pull design and were disappointed when the, you know, the Canon, for example, and the Mark 1
8:06
it was a push pull design and then moved to a traditional, you know, kind of twist zoom action
8:12
not really designed the same way around the push-pull. This is purposely designed with that
8:18
in mind. And so anyway, a nice feature there. EGM lens has a window here for accessing a circular
8:29
polarizer. Sigma doesn't have that. You'll notice there is a nice flare here and also a relatively
8:35
small 6-7 millimeter front filter size. As a result, there's a lot of room to reach in there
8:40
and rotate a polarizer should you happen to use one. And so again, I don't think that that is a
8:46
major loss there. Overall, just to give you an idea of dimensions, this lens weighs in at 1135 grams
8:54
that's 40 ounces. And so that compares to the GM that weighs in at about 1400 grams. It's also a
9:01
little bit shorter than the GM lens by about eight millimeters, 197 millimeters versus 205 millimeters
9:07
and it is also slimmer in diameter. The Canon lens is identical to the Sony, and so you can see that
9:15
the lens, Sigma lens, is quite a bit slimmer, which gives it obviously a sleeker look when it is mounted
9:21
on the camera. And some of you, I know, really prefer having a black lens just because it is
9:29
less, attracts less attention outside. So anyway, it looks good mounted on the camera. As far as the
9:35
weight, it is going to be a little bit of front heavy. It's better to support a lens like this
9:40
with the other hand. And if you're going to be carrying it in a harness situation, I would
9:45
recommend buying the tripod collar and putting your connection point there just so you are putting
9:51
less stress on your lens mount on a regular basis. Overall, I like the build and handling that we've
9:57
got here. It is a fairly feature-rich lens for a bargain lens that costs less than half as much as
10:04
the GM. So you're really not giving up a whole lot if you choose to go with the Sigma. So by and
10:09
large, a lot of good going on here. As I noted, the contemporary brand continues to be a somewhat
10:16
pointless designation to me. All new lenses in one sense are contemporary and before long, even those
10:23
that are new now will no longer be contemporary in that sense. And if it's about design language
10:29
there's nothing any more contemporary about the design than either the art or the sport
10:33
because frankly, they all look pretty similar. So all of that aside, this is a nicely built lens
10:40
not at the level of the GM, but a mix of some good materials there
10:44
It seems quality, durable. I don't think that you'll have any problems
10:48
with it on that front. It's also fairly feature rich, giving up quite little in terms of feature to the GM lens
10:55
Now, as noted, the tripod collar is a separate accessory that will set you back a little over around 120 extra bucks US and you know or you know
11:07
whatever it is in your local market and so you can determine whether or not you want or need
11:12
one for your applications. Now this lens has a stepping motor focus system. My chief criticism
11:20
when I reviewed in 2017 I reviewed the 100 to 400 millimeter contemporary for Canon and Nikon DSLR
11:29
My greatest criticism at that point was, number one, on the physical side, it wasn't really designed with a tripod collar in mind, even in its physical design
11:38
There were some that could be tacked on later, but it was never a magnificent fix
11:42
And so, in this case, they've improved on that by designing this lens purposely with a tripod collar in mind
11:49
My biggest criticism, however, was while the optics in the lens were very good, I was far less impressed with its autofocus performance
11:57
and just didn't find it fast enough to keep up with tracking a fast action
12:02
particularly when compared with, say, the Canon 100-400mm, a more premium lens
12:07
So, how does this guy hold up? First of all, the stepping motor is an improvement when it comes to the sound and the smoothness
12:15
and also the speed of focus. You really won't hear hardly any focus sound unless you put your ear right up next to the barrel
12:23
Most focus changes are near instantaneous. in AFC mode. I just, I point it, I, you know, half depressed the shutter button and it's focused
12:33
And so very, very fast, very smooth, very quiet. And as you can see
12:37
that bears out even for video focus pools. Let's take a quick look at that
12:41
so i mean nothing to complain about there obviously what's most important however is
12:57
how does it perform when it comes to keeping up with tracking action i will note before that that
13:02
you know i saw the typical thing that you know sometimes if you're trying to focus on a close
13:07
object and there's busy background, sometimes it's a little hesitant to grab the foreground object
13:13
However, it obviously does help to use the focus limiter if your background is, you know
13:18
more than six meters away. If not, you know, you typically are going to, you can either manually
13:24
override, often touching on the screen and just kind of detecting a smaller box will help with
13:30
that. But as far as tracking goes, I used my A9. If you go down to kind of optimum settings
13:36
just shooting JPEGs, I got right on 15 frames per second. Now, I know that in theory, my A9
13:45
should give me 20 frames per second. I've actually never seen that, by the way. Maybe your mileage
13:50
may vary, but even with Sony branded lenses, I've been fortunate to get 17 or 18 frames per second
13:56
So 15 versus 17, not necessarily a huge difference. And what I was most impressed by is that I was
14:02
still able to get 13 or 14 frames per second while shooting uncompressed RAWs and extra fine JPEGs
14:09
That's kind of more what matters to me. What I found is that in these tracking sequences
14:15
the focus overall had no problem keeping up. I will note that the actual environment was a
14:21
little bit more challenging. They became very wet, and so byproduct is that a darker face and muzzle
14:27
means that there's less contrast between the fur and the eyes. But overall, as you can see
14:32
I was able to freeze lots of action I don think that the tracking is 100 there with the GM I going to say it more like 85 to 90 but for most people I think it going to be sufficient for you to get a lot
14:48
of wonderful results. Also here, you can take a look at just a panning bird in flight shot
14:54
You can see that the autofocus system stayed on it and gave me successful results throughout it
14:59
So overall, I'm quite impressed with the results I got, particularly since I consider the fact that I believe the Sony lenses were advantaged in my test by shooting snowing conditions where there is light reflecting up, not being wet on the dog's faces, so there's more contrast between the fur and the eyes
15:16
And so I think the Sigma did fairly good in these situations, you know, despite that disadvantage
15:21
And I would say that it probably has given us somewhere between 85 and 90% of the focus and tracking performance of the much more expensive GM lens
15:32
So what was a tremendous weakness for the predecessor of this lens has now become, if not a strength, at the very least, it is now, I believe, competitive with the much more expensive options
15:43
and that's no longer a reason why you should not consider the lens
15:48
And so that's a huge step in the right direction. So kudos to Sigma on that
15:52
So how about the image quality? Well, the good news is this always was a strength for the Sigma 100-400mm optical formula
16:00
Let's see how it holds up though on higher resolution bodies like the 42 megapixel A7R Mark III that I tested on
16:08
Let's jump in and let's take a look at those image quality results. So we'll start by looking at distortion in vignette at 100 millimeters. As you can see
16:15
there is a very mild amount of pincushion distortion, a little bit of vignette, nothing
16:20
too significant. You can see here I've done a mild manual correction that's given us a clean
16:26
end result of both vignette and distortion. Now throughout the zoom range, there's a steady
16:31
increase in the amount of pincushion distortion that reaches a peak at 400 millimeters
16:36
It's not terribly destructive here and it is nice and linear. So as you can see
16:40
cleans up well. Also, vignette has increased, and once again, it cleans up just fine manually
16:46
There isn't, of course, this lens is just being announced, so there is not yet any profiles for
16:51
raw files in software. However, you will have in-camera profile for JPEGs and video right out
16:58
of the box. We've got excellent control of chromatic aberrations. I didn't really see any
17:03
lateral CA and no longitudinal CA here. You can see no green or purple fringing really showing up
17:11
and we've got pretty nice contrast here on our line of focus. Out in the real world in these
17:17
high contrast areas with these white blossoms I'm also not seeing any evidence of chromatic
17:23
aberrations. Very very well controlled and as you can see lots of great detail there wide open on
17:29
this lens. Here's another case in point and it also shows up something we'll get to in a moment
17:34
that this lens actually has quite nice bokeh but we can see once again looking at it from a
17:39
chromatic aberration perspective we really don't have any issues with CA there at all. I will
17:45
quickly note that the Sigma does not suffer from focus breathing in the way that the Canon lens
17:50
does and so here framed at 100 millimeters you can see they were both at the exact same distance
17:55
The Sigma is filling the frame with the chart, and you can see that there is a considerably less than filling the frame with the Canon
18:03
So that's definitely a strength for Sigma there. So just for a quick look overall, just the Sigma itself, you can see at a one-to-one level, nice and crisp there in the center of the frame, good contrast
18:15
Mid-frame, everything looks really great here as well. Right off into the corner, a good performance there
18:22
And so taking independently, we've got a great performance. We'll compare it to the competitors though
18:27
So if we go into a two to one level here, and so really magnifying things
18:32
we can see that there is kind of some give and take in the center of the frame between the Sigma here
18:38
and the GM, and so you can see GM maybe has a hair more contrast
18:42
It also though doesn't have maybe as much detail, and so it's a very close thing
18:49
Looking here at the mid frame, we can see that there is a little bit
18:52
different lighting results, but there's not a dramatic difference. Maybe a slight bit more performance from the GM
18:59
but would be impossible to see without them side by side. Contrast levels are quite similar looking
19:05
and if we look down here in the corner, I do think the GM has got the edge with a very strong
19:10
edge and corner performance. Now, the real benchmark here is the Canon 100-400L Mark II
19:16
which is still, in my opinion, the best lens optically in the class. You can see center of
19:21
frame it's definitely got a little bit of a contrast improvement and a little bit of resolution
19:26
improvement. That remains true mid-frame where you can just see a little bit finer detail a little
19:32
less kind of haze on textures from the Canon and down in the corner the Canon definitely looks a
19:38
little bit better but it's not by a whole lot of a margin either. Now stopping the Sigma down on
19:44
down to f8 doesn't produce a tremendous increase of resolution a little bit more consistency in the
19:51
contrast, but it's not making a major difference at 100 millimeters. Now, if we move on to 200
19:56
millimeters against the, you know, top flight Canon, we find that there's definitely an edge
20:02
in the overall contrast for the Canon. Not a huge margin, but definitely noticeable. Mid-frame
20:09
just a little bit more contrast. Detail and resolution is more similar than different
20:13
We'll take a look at another spot, and I draw the same conclusion there. Down in the corner of the
20:19
frame, we find that, again, it's mostly about contrast. I do think there's a bit more resolution
20:24
for the Canon, but it's not by a wide margin. It does have better contrast wide open across the
20:29
frame. With the GM lens, the difference is a little less obvious. These two are quite close
20:35
here in the center of the frame with a tiny contrast edge for the GM. Mid-frame here
20:41
it's kind of the same story, very, very, very similar, not a huge amount of difference
20:47
down in the corner of the frame, I would say the same is true. I don't know that you would see much
20:51
of a difference between these two results in the real world. And so I would call it a draw
20:58
Now, if we move on to 400 millimeters, arguably the most important part in the focal range
21:03
we find that the Sigma actually holds up really well and is arguably a little bit better in the
21:09
center of the frame than what even the Canon is. At the mid-frame point, the Canon, I think
21:14
has a little bit of an edge, but they are very, very close. And here, if we look towards the outer
21:20
edge of the frame, we see that the Canon is a little bit better at the periphery of the frame
21:26
but a really strong performance from Sigma. Now, if we compare to the GM lens, and obviously the
21:31
framing was a little bit different at the time of taking these tests, but what you'll find is that
21:36
once again, the Sigma competes really well in the center of the frame. If we take a look mid-frame
21:42
Also, the Sigma is looking quite good by its competition there, and so standing up strong
21:49
It only down in the extreme corner where the Sony shows an advantage at 400 millimeters and so the Sigma is arguably better in the center of the frame and even mid It only at the edge where the GM is a little bit better Stopping on down to F8 gives us a little bit
22:05
of a contrast boost, but not a major, major difference here. So in real-world performance, even at a two-to-one level here
22:13
you can see that we've got a lot of detail that is rendered here on this little Robin
22:19
And in fact, if you look at it at just a pixel level, It looks really, really fantastic
22:24
I'm also impressed overall by the colors that I see, which are nicely saturated, nicely detailed
22:30
and deliver great looking images. The 0.24 times magnification isn't quite as good
22:35
as either the Canon or the Sony GM. However, as you can see, we do have a nice detail
22:42
and contrast that is rendered at minimum focus. So it does make it very useful
22:47
You know, here, case in point, you know, that's a beautiful image, great color
22:51
A nice detail here on the tulip. And of course, the background at 400 millimeters is just crushed
22:58
leaving you a really, really beautiful looking, unique result. The bokeh quality is good even at difficult distances
23:06
which I would consider this to be. So we've got good detail on our subject, great color
23:11
And the bokeh, even though the distance doesn't allow this to be like a cream
23:16
it looks fairly good. You can see some deformation along the edges of the frame, however
23:21
And I thought here again, kind of a challenging middle distance that the bokeh quality actually
23:26
looks quite good. And of course, our subject looks great. When you get up close, you can really
23:32
really destroy backgrounds and blur them out beautifully. And it makes for a beautiful end
23:37
result. You can see that here as well. Just a result that I really, really like. So you can
23:43
of course, stop lenses like this down and use them for landscapes. Just note that as you can see here
23:50
that even at f8, the depth of field is still not deep enough to include all of the scene
23:58
And so you do have to kind of bear that in mind. It's better when shooting a really distant subject where everything's going to be in detail
24:05
But as you can see, the detail, contrast, and color of the image looks great
24:10
One other thing to watch for over long distances like this, if you're going over long distances where there might be differing air pockets
24:17
you can see here that it's almost like a oil painting, and that's a byproduct of those layers
24:24
So out to about here, you can see that it's okay, but beyond that, it's a different kind of thermal pocket
24:31
and that really does play havoc in fine detail. So as far as the real-world OS performance
24:37
again, remember that OS really, it's not gonna ever stop any movement of subjects
24:42
and so what we're looking at is if we have a still subject, if it is stabilizing
24:46
In this case, this is 400 millimeters and 1 40th of a second. And so that's three and a third stop of assistance on this shot
24:54
But as you can see, it's done its job. There is no evidence of motion blur even on a high resolution camera
25:01
Now, in this case, we have got 1 10th of a second at 100 millimeters
25:05
And again, I wasn't necessarily trying for these images. This is where I find the value of OS is and that these shots
25:12
I just wasn't paying enough attention in AV mode how low the shutter speed was getting
25:16
and the lighting. And so byproduct though, is that as you can see, even at one 10th of a second
25:21
no sign of motion blur, all the detail looks nice and crisp. And so that is the value of a good OS
25:28
system. So finally, let's take a look at our flare resistance. And so you're not going to often
25:33
point a lens like this into the sun, particularly on the long end, but here at a hundred millimeters
25:39
with the noonday sun in the middle of the frame, you can see just a little bit of veiling and a few
25:44
little ghosting artifacts. If we move the sun's position up into the corner, you can see the
25:49
longer kind of flare pattern there. Not too destructive, however. And then finally, if we
25:55
stop it down, it doesn't really get a whole lot worse here. And so good results there. Moving on
26:01
to 400 millimeters, you can see that there's a little bit more veiling. The ghosting pattern is
26:06
really kind of broad at wide open. And then going to a stop down and putting it into the corner
26:12
you can see a little bit more of a ghosting pattern but again overall it's not too bad
26:18
So as you can see I consider that to be actually quite a strong performance considering that
26:23
there is some give and take over the of the zoom range between all of these lenses and considering
26:29
that the Sigma is priced so much cheaper than the alternatives I think that that really is
26:35
actually a recommendation under the circumstance and so I would put it this way I would say that
26:41
when it comes to the build and to the autofocus system, you're getting somewhere between 85% and 90% of the performance
26:48
However, when it comes to the optical performance, you're very close to 98% to 100% of the overall optical performance
26:57
with one exception, and that is, I will point out, now, the GM lens is not great in this regard either
27:03
but comparative to the Canon, for example, I find that the Sigma loses maximum aperture quite quickly
27:11
So it's f5, yes, but it's only f5 until about 112 millimeters
27:17
So about 12 millimeters, and then it becomes f5.6. Then somewhere around 236 millimeters, it becomes f6.3
27:25
So that does mean that throughout some of the range, you're going to have a disadvantage when it comes to maximum aperture
27:31
You know, at most, one-third stop relative to the Sony. The gap's a little bit larger sometimes relative to the Canon
27:38
But, you know, there's one criticism I have. But I also, I believe actually the bokeh quality from the Sigma to my eye is more pleasing than what I saw from the G Master
27:48
So that's another perk in favor of this lens. So at the end of the day, this is a strong performance from Sigma
27:56
I think it's going to really fill a need that's existed on the Sony system of a lens with a focal length like this
28:03
but one that the masses can possibly afford. and the GM of course being out of reach for a lot of people just on a practical level with their
28:12
budgets and so kudos to Sigma for helping to plug the gaps and I'm so glad to see this lens come to
28:17
market. Now if you want one I understand that they will start to ship somewhere in early July and so
28:23
you might want to get a pre-order in if you are interested. I do have buying links in the description
28:28
down below however this lens is just being announced on the day I'm releasing this review
28:32
So you may have to give it a day or two for some of those links to start to populate
28:37
And with some retailers, it may take a little bit longer than that. But be patient and, as always, appreciate if you use the links below if you decide to purchase this and help to fund to keep this channel going
28:49
There's also linkage there to my full text review with a lot of comparison. You can take your time there, and I think it'll help your buying decision
28:56
Linkage also to an image gallery. and, of course, the standard links to follow me on social media, become a patron, sign up for my
