We’ve known that Viltrox’s LAB series was coming for about two years, and I, for one, was very excited for the series. Viltrox has proved to be capable of doing very serious optical engineering, and, put simply, the LAB series was proposed as being Viltrox’s “G Master”, “L Series”, or “S-Line” equivalent lineup of premium lenses. Of those, the LAB lenses are probably most like Nikon’s S-Line lenses where the engineers have clearly been told not to worry about size, weight, or cost, and just deliver the best optics at that particular focal length possible. The LAB lenses may not be expensive (they are actually tremendous value!), but they are among the largest and heaviest lenses in their class, and are definitely optically superior. I was very impressed by the optics of the first LAB lens – the AF 135mm F1.8 LAB FE – that I reviewed here. It was optically amazing (besting great lenses like the Sony 135mm F1.8 GM and the Samyang AF 135mm F1.8), had great autofocus, and struck an amazing balance between sharpness and rendering. But I also knew that Viltrox had a trio of F1.2 LAB lenses on their roadmap, including 35mm, 50mm, and 85mm F1.2 options, and I was very excited about those as Sony has relatively few high end F1.2 options available. The Viltrox AF 35mm F1.2 LAB is here, and it is another landmark lens. And, at a price tag of $999 USD, it is a pretty huge value (and if you use code DA3512LAB5 at checkout at Viltrox, you can get an additional 5% off!).

Thanks to Viltrox for sending me a review copy 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 and the Sony Alpha 1. You can find the listing for the AF 35mm F1.2 LAB FE here.

Sigma was actually the first to bring an F1.2 autofocusing lens to the Sony FE platform back in 2019. I reviewed that lens here. It was optically impressive (extremely sharp!), but was also very large and quite expensive. It weighed a whopping 1090g (2.4lbs) and cost about $1500 USD. A lot of its thunder was stolen when Sony released their FE 35mm F1.4 GM lens (my review here) in 2021. It was (and is) an amazing lens, and while it isn’t quite as bright (F1.4 vs F1.2), it is amazingly compact, weighing only 525g. It was the 35mm lens that I added to my own kit, and I’ve not regretted that decision. The 35mm LAB is more like the Sigma than the GM in size, however, though fortunately they have managed to trim the size a bit. The 35mm LAB weighs 920g (-170g vs the Sigma) and is about 15mm shorter. Still a big lens, but it will have a couple of sales advantages vs the Sigma. One is the fact that it is smaller and lighter, but also the Sigma actually ended up being MORE expensive than the premium Sony lens (since Sony doesn’t have a 35mm F1.2 GM lens), whereas the LAB lens will be significantly cheaper. And, unlike Nikon’s new 35mm F1.2 S Line lens, the LAB 35 is actually significantly smaller than the LAB 135mm!

I love 35mm lenses. I love the focal length for general purpose shooting, and, more importantly for this particular application, for environmental portraiture. The advantage of a wider focal length is the ability to add context to a shot. To include the room, or the setting, or the environment along with the subject. But the downside is that the depth of field increases, and you often lose the ability of really isolating your subject from the background. A 35mm F1.2 lens restores that ability, however. At a distance of the 3 meters (close to ten feet), a 35mm F1.2 lens has a depth of field of about 50cm (20 inches). With an F2 aperture, that depth of field nearly doubles, at F2.8, it nearly triples. In other words, a fast maximum aperture is very necessary to create a shallow depth of field with a wider focal length. By contrast, an 85mm F2.8 lens has a depth of 21cm. You could stop down to F6.7 and still have the same depth of field at that distance as a 35mm lens at F1.2. For portraiture I might argue that a fast maximum aperture is more important on a wide angle lens than it is on a telephoto. Bottom line is that you couldn’t get shots like this on a slower 35mm lens:

And, despite being at F1.2, you can see from the deep crop that the image is sharp and crisp on the subject (despite the intense backlighting), and there is a nice separation of the subject from the background.

Nice, indeed. There are going to be a lot of people interested in this 35mm LAB on both Sony and eventually Nikon when it arrives there. Let’s dive a little deeper into the build…

Viltrox LAB 35mm Build and Handling

As noted, this time Viltrox has the advantage that the 35mm LAB isn’t the largest and heaviest lens in the class…but that doesn’t mean it is small or light. It is 89.2mm (3.5″) in diameter and 121.8mm (4.79″) in length. It has a common 77mm front filter thread up front and weighs in at 920g (32.45 oz). It has a great aspect when viewed from the front.

The compact size of the 35mm F1.4 GM while still being high performing is going to continue to be one of the most compelling arguments for the Sony lens (particularly for those who feel that F1.4 is bright enough for them). It is only 96mm in length (-25mm) and weighs just 524g (-396g!) However, a more apples to apples comparison might be the new NIKKOR Z 35mm f/1.2 S, which is 150mm in length (+29mm – wow!) and weighs 1060g (+140g). It also costs $2800! So there is at least one lens that will make the 35mm LAB feel at least a bit svelte…though it isn’t the compact little Sony below.

Viltrox has demonstrated that they are capable of producing small, lightweight lenses with good optics, but that’s not the point of the LAB series. I feel like they are probably most similar to those Nikon S-Line F1.2 lenses, which eschew trying to keep the lenses small and light (and optically compromising to achieve that) and instead focus on just making as good of optical instruments as they can. The downside of this philosophy is that it results in some beefy lenses.

Viltrox has persisted in a few of their LAB design cues from the LAB 135mm, and I don’t love all of them. The most notable of those is the approach to aperture control.

Some of Viltrox’s other lenses have (and will have) a more traditional approach to aperture similar to either Sony’s GM series or Sigma’s better DN prime lenses. This is a marked aperture ring that can either be clicked or declicked. For some reason Viltrox left that tried and true approach for a new approach more dependent on the LCD screen. The first ring on the lens is for aperture, but it is an unmarked ring that relies on the LCD screen to show you the selected aperture.

That being said, I’ve recently spent time with the Nikon Z-mount version of the LAB 135mm, and then also Nikon’s own 135mm 1.8 S Plena. I realized that my perceptions of Viltrox’s design strategies with the LAB series were being influenced by first reviewing these lenses on FE. Some of the design philosophy around the “aperture ring” makes more sense on Z-mount, as the standard there is that the customizable control ring can be used for aperture but can also be used to control other things, like exposure compensation, ISO, etc… On Sony we don’t have the options to change the function of the control ring, so it has to function like an aperture ring, so on Sony (at least), I would prefer a more traditional aperture ring.

You still have the option to have the ring either clicked or declicked, but in the clicked mode it has clicks at every 1/9th aperture stop rather than the typical one third aperture stops. I assume the logic is to provide more precision, but frankly it is wasted when A) Sony cameras only register one third stops and B) the LCD screen shows only one third stops between the full stops like F2 and F2.8. In real life it just feels like too many clicks, and I don’t enjoy it. It also makes the amount of rotation needed to go from F1.2 to F16 just too long. A more traditional aperture control setup would have been preferable all around. You can still rotate all the way to the left and move into automatic mode, and I suspect some people will probably prefer to just control aperture from within the camera. You do have the option to turn the clicks off as well via a switch on the left side of the barrel.

In theory, when you turn the clicks off you can smoothly move through the whole aperture range without defined stops.  This (in theory) allows for smooth video aperture racking and has become an expected pro-grade feature on modern lenses. I find two problems with this on the 35mm LAB. The first is that the weight is still a little heavy on the aperture ring even when it is declicked (clicks are very definite in clicked mode). This makes moving smoothly (and slowly) when racking through the aperture (to allow the exposure to change in a non-obvious way) challenging. The second issue is that even when declicked, the aperture does not move in a completely linear fashion. I can still see a bit of visible steps when racking. The best lenses do a pretty good job of simulating a true manual aperture ring, but the 35mm LAB falls a bit short of that lofty goal. It’s far from the worse that I’ve seen, but also far from the best.

The iris itself has 11 aperture blades, and these make for a reasonably well rounded aperture iris when stopped down. It’s not until fairly small (F4-5.6) that I start to see the shape of the blades.

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. 

I’ve even noticed that this time they are showing you a depth of field scale if you are in manual focus mode that increases as you change the aperture by extending a yellow bar along the distance scale.

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.

On the left side of the screen you will find 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 works by default as the main control for A-B focus. When in manual focus mode you can preset the focus position(s) by long pressing the FN 2 button, and then access the focus changes by short pressing it. You also have the ability to change the function of both function buttons through the Viltrox app.

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 doing firmware updates through the camera.  This allows Viltrox to future proof their lenses and continue to improve them through firmware. You also have the option to connect to the Viltrox app for IOS or Android via Bluetooth where you can also update firmware wirelessly…or even make a direct correction via USB-C from your phone to the lens. In the app you can go beyond firmware updates to tweaking the behavior of the custom buttons.

You can even customize the splash screen on the LCD at power-up to show your name or logo.

The one thing I wish was there but isn’t (at least yet) is some control over the function of the manual focus ring. I’d like to be able to choose between linear/non-linear focus and the amount of focus throw rotation similar to what Tamron allows on some of their lenses. I wouldn’t be surprised to see Viltrox get there; they are pretty ambitious.

The manual focus ring is slightly raised and has a rubberized, ribbed texture.  It moves smoothly and with nice damping. It isn’t linear, so the amount of focus covered will depend on the speed in which you rotate the ring. I found the focus throw to be a little long when trying to do smooth pull for video…at least at close distances. It needed more rotation than I could do with a single wrist rotation. 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.  This is a professional grade lens with professional sealing. As always, however, “moisture-proof” does not mean “water-proof”, so don’t go crazy!

There is no lens based stabilization, so you will need to rely upon the in-camera stabilization if your camera is so equipped. Handholding a 35mm F1.2 lens is rarely difficult.

Like the 135mm LAB (and the upcoming 85mm F1.4 Pro), the 35mm LAB employs floating elements. You might notice 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. This allows for superior up close performance. You can focus as closely as 34cm, giving a maximum magnification figure of 0.17x.

That’s a useful but not exceptional figure. The Sony GM can focus closer (25cm) and gives a 0.26x magnification level. The Nikkor 35mm F1.2 S can focus as closely as 30cm and gives a 0.20x magnification. But what the LAB does extremely well is give you amazing up close performance even at F1.2. Look at how exceptional that detail is in the crop.

The lens also comes with 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 35mm includes a lens hood that isn’t quite as premium feeling as the one on the 135mm, but it still feels like good quality. The plastics are thick and it has internal ribs. It doesn’t have a lock, but it does bayonet into place firmly and with a definite “click”.

The lens is constructed with a aviation-grade magnesium-aluminum alloy, making it extremely tough. The finish of the lens feels every bit of premium as the more expensive Sony GM lens, and the LAB badges manages to fall in the same spot and be the same color as the “G” badge on the Sony lens…though I’m sure that’s a coincidence (wink, wink).

As with the 135mm LAB, the Viltrox AF 35mm F1.2 LAB E is a premium lens with a robust set of features. I don’t necessarily agree with all the design decisions, but it is a very, very nice lens. It’s also pretty big and heavy, so that will be a serious factor for some.

Autofocus and Video

Like the LAB 135mm, the LAB 35mm utilizes four(!!!) of Viltrox’s new “Hyper VCM” (Voice Coil Motor) motors working in tandem to drive autofocus. Viltrox states, “Its double floating magnetic suspension system ensures precision focusing, whether you’re tracking a fast-moving subject or shooting videos.” Focus is extremely quiet and fast. I had no problem keeping up with fast squash action on the court…even at F1.2.

Grabbing quick, reactive shots at F1.2 was very easy to execute.

Focus on thin objects with shallow depth of field was effortless, and the lens yielded excellent precision.

Focus sound is near silent, with a very light whirring sound as focus moves back and forth that I can only hear if I put my ear right next to the lens barrel.

I was very impressed when testing for focus speed. It is essentially instant when moving from a foreground to a background subject. I tested with the Sony GM back to back, and actually felt like the Viltrox had a split second advantage. Both are extremely fast, so it feels a bit like splitting hairs, but that helps put the Viltrox’s performance in context.

As mentioned in the intro, I was able to get accurate focus on the eye even when shooting portraits with strong backlighting.

I had no problems nailing focus at F1.2 during a teaching session at a church.

You can also see great precision in this shot of a horse. The lashes were covering the iris, but the precision and detail (at F1.2) is great.

I had no problem snapping focus to a bird on the wing.

If we look at a crop where I’ve raised exposure, you can see that the shot is perfectly focused.

And, of course, here is the obligatory shot of Nala.

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.

I will add one caveat, however. While the Viltrox is fast enough to keep up with a quick moving action, burst speed is limited by Sony to 15FPS. If you are using one of their sports bodies, like my Alpha 1, that means that you can only achieve half the maximum burst rate that you can with a native Sony lens. That difference will be even more pronounced on a camera like the a9III. One of the nice things about the LAB lenses on Nikon is that no such limitation exists.

Video AF

The focus excellence carries over the video side of things. Video focus pulls are smooth, quick, and confident. The advantage of not having a STM (stepping motor) is that there are no visible steps, allowing focus to move consistently and smoothly from one subject to another without any visible pauses. There is some focus breathing, but it is fairly well controlled, with only a slight change of subject size depending on focus (I’ve put some lines here so that you can see the amount of size change).

The Sony 35mm F1.4 GM has a bit of a reputation for breathing quite badly, and you can definitely see that the GM has more obvious breathing…however…Sony has a focus breathing compensation correction on their cameras that utilizes a crop to mathematically eliminate focus breathing. It only works for first party Sony lenses, however, and it’s a pretty significant crop for the 35GM because there is so much breathing.

So, the Viltrox has less breathing, but that breathing will not be corrected in Sony cameras, either.

My “hand test” where I alternately block the camera’s view of my face with my hand and then remove it went exceptionally well. Focus confidently moved from my hand to my eye and back without any pulsing or lack of confidence. The focus breathing means that you will see the pull from my hand to my face, however.

Focus stayed stable in static shots at various apertures and didn’t pulse or move around.

I would say that autofocus for both stills and video is generally excellent. Viltrox’s new Hyper VCM focus motors are pretty great.

Image Quality Breakdown

The 35mm LAB continues in the tradition of being, well, exceptional. The optical design is 15 elements in 10 groups, with five of those being ED (low dispersion) elements, three of them being HD (high refractive index) lenses, and two being extreme aspherical lens (so two-thirds of the elements here are exotics). The MTF at F1.2 looks very good, with an absolutely stunning center and midframe performance and then a fade into the corners. At F8 the MTF is pretty much a straight line across the top, i.e. perfect.

Not everyone understands MTF charts, so I won’t do a deep dive into them here, but what I do find helps people visually is if I line up the MTF charts from alternatives, put a line through 80% (anything above that is looking great), and allow people to see what falls above and below that threshold for each lens. In this case, I’ve grabbed the premium Sony FE 35mm F1.4 and the new and exceptionally expensive Nikkor Z 35mm F1.2 S. The results are illuminating.

By this metric, the LAB lens will have the sharpest center and midframe with only the GM having sharper corners. I haven’t yet tested the Nikkor, but, on paper, the LAB will be the sharper lens essentially across the frame.

And yes, in the real world, this is a lens perfectly capable of producing stunning results even at F1.2:

Look the precision in the fine details after an ice storm. The contrast is pretty much perfect…even at F1.2.

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 fringing.

I don’t really see any fringing in this shot of water droplets…one that I’ve often found plays havoc on lenses with lesser control.

I did find a bit of fringing at F1.2 when shooting a camera/lens combo, which is my favorite subject for finding fringing (and I like taking pictures of cameras!) The amount of LoCA here is mild, but visible.

We’ve also got near-perfect corrections for LaCA (lateral chromatic aberrations) that typically show up along the edges of the frame with high contrast transition points.  I see only the tiniest amount of fringing here.

I see no evidence of fringing in the transition areas near the edges of real world images, either.

I have seen some VERY unfortunate results in the past year when it comes to fast 35mm lenses and their quantity of vignette and distortion (hello Canon 35mm F1.4L VCM!). There’s much less of that here, though not the perfect levels we saw with the 135mm LAB.

There is a very minor amount of distortion, though unfortunately what’s there is complex. It is neither a true barrel or pincushion distortion, but a non-linear mix of the two. You can see that the corners have a pincushion look while the center is pretty neutral. Trying to correct the pincushion distortion creates barrel distortion elsewhere. I found that dialing in a minimal -2 was the best compromise I could achieve. When the actual correction profile arrives it will certainly do a better job. At the moment there is no correction for JPEGs, either, which will almost certainly change down the road. Fortunately the quantity of distortion is low enough that I couldn’t see it in real world shots.

This horizon looks pretty straight even without any corrections.

However, in this shot, with the horizon right up near the top of the frame, you can see a bit of that “mustache” pattern.

You would probably want to correct that…which will be much easier once this lens has gone to retail and we get RAW correction profiles for Adobe and other editing software. I did find that doing a miniscule -1 in Lightroom’s distortion slider did help enough that I wouldn’t probably notice after correction.

Vignette is moderately heavy at F1.2, requiring a +70 (between 2 and 3 stops). A lot of that clears naturally by F2.8, as you can see here.

At wide apertures, this is often a visible amount of vignette but not necessarily a negative amount. In this portrait shot (uncorrected) you can see that there really isn’t any destructive about the vignette even at F1.2.

There are going to be situations where a bit of vignette is flattering or productive. Bottom line is that while the 35mm LAB has a bit of distortion and a moderate amount of vignette, neither is extreme.

We’ll move on to inspecting our test chart.  This test has been done on a 61MP Sony a7RV sensor.  I use a high end tripod and two second camera delay to ensure vibration doesn’t affect images.  *I ran into an issue that I sometimes encounter with third party lenses in that metering for my test chart didn’t work properly at smaller aperture if the aperture was declicked. I would get overexposed results at F11 and F16. This isn’t the case when testing with the aperture clicked. Firmware should be able to fix this issue.

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 F1.2 from the center, mid-frame, and lower right corner, we find that center and mid-frame performance is exceptionally good, and the corners are good but a bit softer.

So let’s put that in perspective. The premium lens in the class is the Sony 35mm F1.4 GM, which I have owned for years and consider to be exceptionally good. The LAB 35mm is sharper everywhere save in the corners, where the GM has a bit of the edge (as the MTF chart suggested).

But that was with both lenses wide open. If I stop the LAB down to F1.4 and sample the upper left corner, I would give the win to the LAB with both lenses at F1.4.

So this is definitely a very sharp lens at F1.2. I didn’t hesitate to shoot with it wide open at all.

Even landscape images at F1.2 look great:

By F2 the sharpness has increased to the level where my a7RV is struggling with moiré (false color). That only tends to happen when lenses are very, very sharp.

Even the corners are now extremely sharp.

Landscape images shot anywhere between F2 and F8 will look fantastic. Here’s one shot from a car window at F2.8:

This shot of a pier at F2.8 looks great everywhere that is in focus.

If I check back in with a comparison at F2.8 with the GM, I find that while both lenses are ridiculously sharp, the LAB is just a bit sharper everywhere. Take a look at the smaller text in this comparison.

Also interesting is the fact that the LAB consistently required less exposure (faster shutter speed) even when I shot both lenses with the same settings in a controlled environment. Clearly the LAB lens has a bit better light transmission (perhaps not surprising considering its more robust size).

Landscape images in the middle apertures show plenty of punch and detail. Colors are rich, contrast is strong, and detail is great even on a 61MP camera.

As is typical on a high resolution body, diffraction will 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!)

Clearly this is a very sharp lens. But we aren’t just looking for sharpness; can this lens also deliver soft bokeh? It is a rare lens at any focal length that is good at both. 35mm lenses aren’t necessarily the biggest “bokeh makers”, but I’ve seen a few that could deliver lovely bokeh.

Here’s a look comparing the LAB and GM. We would expect the specular highlights to be larger on the LAB due to the faster maximum aperture, and that is the case. Both lenses experience some “cat-eye” geometric deformation near the corner of the frame, though the LAB experiences less of it.

What’s interesting here is that I actually think that the rendering from the LAB is nicer. By that I mean the mix of color, defocus, and general look to the image.

What many people don’t know is that due to some quirk of physics the specular highlights of a brighter lens remain a bit larger and softer than a lens with a dimmer maximum aperture even when you equalize the settings. If I stop the 35mm LAB to F1.4, for example, it still has bigger, softer “bokeh balls” than the GM at F1.4:

We see a little busyness in those specular highlights, but nothing too bad.

This next shot has a lot going on in the frame. It’s a gift shop that is full of various items and knick-knacks. There are also a number of bright lights and small objects that make for a complex bokeh rendering in both the foreground and background.

What we see is excellent subject isolation and fairly smooth rendering on all of those various textures…even the ones likely to induce “nervousness” in the rendering.

A gentler scene produces a more creamy background.

Obviously at closer distances and F1.2 the background will be strongly defocused and will look nicely creamy.

I think that most people are going to be very happy with the rendering from the 35mm LAB, and will love that extra bit of subject isolation that you can get from an F1.2 lens. I’m not sure it’s bokeh is as nice as my favorite 35mm bokeh maker (the Zeiss Milvus 35mm F1.4), but it is pretty close.

I also felt like colors are very nice and rich from the 35mm LAB. It’s a little ugly at home right now as we (very slowly) transition from winter to spring (mostly still winter!). That wasn’t a problem in Myrtle Beach in March, however, particularly when I was up early to catch the predawn light.

I felt like my real world images had very rich color to them.

Flare resistance was also very strong, which is hard to do in a lens with such a huge maximum aperture. I’ve tested a lot of cheap F1.2 and F1.4 lenses that have massive flare issues, but I saw (at most) the tiniest amount of ghosting in all of my testing period.

Contrast remained strong even in strongly backlit situations. This adds a lot of additional versatility for portrait photographers, as they can shoot backlit subjects without fear of their images falling apart.

I did manage to test coma. A 35mm lens with an extremely bright F1.2 aperture is going to be a potential favorite for those wanting to shoot the night sky. How did it do?

As you might expect by this point, this is a lens that is pretty much good at everything. Astro is no problem, even at F1.2, with no issues with fringing around bright points of light, crisp star points in the center frame crop, and very little coma near the edges of the frame in the second crop.

I’ll be honest; I actually didn’t expect this lens to rival the 35mm F1.4 GM, which is perhaps my favorite 35mm lens to date. Now, to be fair, the GM is working within much tighter size constraints, but the fact that the Viltrox AF 35mm F1.2 LAB FE is so good and so comparatively inexpensive ($500 less!) makes for a pretty compelling option.

Conclusion

I was excited by the idea of the Viltrox LAB series lenses from the moment that they were announced, but the reality of them has been, if anything, even better. These LAB lenses have been so good that I’ve scaled up my expectations (and critiques) of them to the level that I would hold lenses that cost 2-3x as much to. That’s mostly because Viltrox has proven that they are pretty much capable of anything.

While Kazuto Yamaki (CEO of Sigma) did announce a MK II version of Sigma’s own 35mm F1.2 for Sony FE, at the moment of this review the Viltrox LAB 35mm F1.2 is the only autofocusing 35mm F1.2 lens on FE since Sigma had previously discontinued the existing 35mm F1.2 DN. I’m not sure what level of sales success that the first generation Sigma had on Sony FE, but that fact that the Viltrox is the superior lens in both optics and autofocus, is smaller and lighter, and costs nearly half as much will probably give it a sales advantage. Add to that that this lens will also eventually come to Nikon Z, and I suspect that the 35mm LAB will do just fine.

The Sony 35mm F1.4 GM is a still a lovely choice if you want both high performing and compact, but the LAB 35mm is the new champ if you want that next level F1.2 goodness. It can produce brilliant images at all apertures, nail autofocus in those critical moments, and won’t break the bank. It may break your back, however, though no more so than a lot of the Sigma ART series primes from back in the day. And if you want a lot of this magic in a slightly smaller, lighter, and cheaper package…their 35mm F1.4 Pro lens is coming somewhere in the near future. I’ve already been testing the 85mm F1.4 Pro, and it is pretty sweet. It’s a good day for Viltrox…which means that a lot of other lens makers may be having a bit of a bad day.

Pros:

• Not as massive and heavy as the 135mm (or the 35mm F1.2 S-Line)
• Beautiful built lens
• Feature rich
• Very good weather sealing
• USB port for firmware updates along with Bluetooth for wireless access
• Quad HyperVCM motors means focus is near instant
• Focus pulls are nicely damped
• Exceptionally sharp lens that matches or bests the very best in the center and mid-frame
• Minimal distortion
• Strong control of fringing
• Colors look great
• Amazing contrast
• Beautiful bokeh
• Great flare resistance
• Low coma
• Amazing price to performance ratio

Cons:

• Big and heavy
• Don’t love the aperture ring design
• A few niggling bugs that need to be corrected
• Aperture racking shows a bit of visible stepping
