I didn’t think that it could be done, but Viltrox made a 35mm f1.2 autofocusing lens that I want to carry around with me all the time. And I’m not talking about for just work, but a true 35mm f1.2 that is light enough to want to always bring around with you. What’s more, it boasts great image quality and weather resistance.

The Big Picture: Viltrox 35mm f.2 FE Lab Conclusions
To recap what I say later on in the review, I’m considering getting rid of all my Sony lenses and just keeping Viltrox around with Tamron for zoom lens coverage. I never thought that a brand would make a 35mm f1.2 lens that I’d want to bring around all day. But this is lightweight enough, small enough, and performs so well. I’m so shocked that this lens exists and I’d gladly take it with me on a vacation as the only lens that I bring with me.

After firmware updates have fixed pretty much all of the big problems, we’re updating this reivew to give this lens our Editor’s choice award and five out of five stars.

- Pretty affordable
Cons
- Disabling the aperture ring isn’t as apparently easy as you’d think, but once you get the hang of it, it’s fine.
- It’s a big lens
Gear Used
Here’s what we used:

Innovations
There isn’t much that’s innovative about this lens. However, it is the first to include the little LED screen up top. That, and there aren’t many 35mm f1.2 lenses out there. Sony will surely be taking this lens seriously as they’ve recently been considering Viltrox to be a serious contender.
Who Should Buy the Viltrox 35mm f1.2 FE Lab?
This lens is for all types of documentary shooters.
Hardware




First off, I need to note that the Viltrox 35mm f1.2 FE Lab is very well built. There’s metal, plastic, and rubber involved with the construction. It feels good in the hand and it isn’t a problem to bring it around for a whole day of shooting. In fact, I brought this lens for a 13.5 mile walk here in NYC. It felt a whole lot lighter than anything I’ve used from Sigma in the past.
One of the most impressive things about this lens is the fact that it has a whole lot of weather resistance, which some folks wrongfully label as weather sealing. We took it out into the rain for a shooting session and it didn’t fail at all. If anything, Sony’s cameras are more likely to fail in the rain.
When I held this lens along with the 135mm f1.8 from Viltrox, I see commonalities. And if anything, I’m considering getting rid of all my Sony lenses. I’d keep Viltrox for their prime lenses and Tamron for their zooms.
Focusing

Autofocus with the Viltrox 35mm f1.2 FE Lab isn’t totally its strongest suit. While it’s good, I truly think that the 135mm f1.8 was much better. However, most of the testing I did with the lens was with it on not the final firmware update. Once that was done, things changed and seemed a bit snappier and more accurate. Note that with older Sony cameras, it won’t be able to do AF tracking when animals are selected unless you’re in specific autofocus modes. In contrast to Tamron, which Sony partially owns, Tamron lenses will have no issues at all with tracking in similar situations.

Focusing Update August 2025
Viltrox added new firmware to the 35mm f1.2. Here are the details below:
1.0.5:
- Fixed known issues. (Upgrade via PC software)
V1.06
- Improve the stability of lens focusing.
- Fixed the issue of inaccurate AF when magnifying and focusing.
- Resolve the abnormal problem when using touchscreen for continuous focusing on the camera.
- Add the function of setting the rotation range for MF focuing in the APP.
- Add the function of mapping FN keys to set the lock for the multi-function ring and focusing ring in the APP.
V1.07
- Fixed the abnormal issue of the camera lens after installing a flash on some cameras.
The autofocus is incredible and pretty much G Master level now. I tried this with and without haze filters and in both situations, it was very fast. I’d gladly use this lens for so many different things and if you shoot Sony, then it’s easy for this to become your favorite. It’s overall quite great to see and feel; so much so to the point where I’d pretty much only want to shoot Sony again. And that’s hard for me to say, as I otherwise find Sony cameras to be very drab.
In fact, I gave away nearly all my Sony primes except for the 55mm f1.8. And honestly, I don’t regret it at all. Viltrox gave theis lens and pretty much all that we review to the Phoblographer and didn’t expect them back. And for that, I’m blessed; but we need to declare this as journalists.
The flash issue persisted with my Profoto light until I switched to Tamron and Sony glass. Then I switched back to Viltrox and it was fine. It’s a weird anomaly, and I’ll surely say that it still persists.
Sony’s hot shoes are also notoriously bad with weather sealing and prone to breaking down after a few years of use. So the issue could instead have to deal with that.
Still, I originally faced autofocus that I’d expect from Sigma lenses. And now it’s leaps ahead of what Sigma offers. Quite frankly, I’d even argue that it might hold its own against Tamron in some very rare situations.
Focusing Update February 2026
The firmware was updated via the mac and the firmware update program. It’s really awesome that Viltrox was THIS fast on updating the firmware. But admittedly, we’re behind on updating our reviews because of the holiday season.
In my tests with the Sony a7V, the Viltrox 35mm f1.2 focused really quickly and most without any faults. It did so with the setting effect set to on and off both – which has always been a bane for many camera manufacturers. This is truly impressive for many users who use the Live View setting effect. I tend to turn it off because I don’t want my camera doing the thinking for me.
Where I found there to be the most issues has to do with focusing at f1.2 without scene detection mode turned on. This is problematic if you’re shooting something like products, food, or anything that isn’t detected by Sony’s AI system. Granted, it could probably even happen with the AI enabled.
After I did my initial test, I realized that I was in both AF-A and AF-S modes – something that many Sony users seem to be allergic to. So I switched to AF-C but only after mounting the Sony Zeiss 55mm f1.8 and the Tamron 35-150mm f2-2.8 on the camera and trying it out. In the AF-C mode, Viltrox’s lenses felt like older Sigma lenses in that the autofocus seemed to hunt and struggle though not as badly as it was before.
Ease of Use
Turn the aperture all the way stopped down and then you can control it via the camera instead of the lens. Otherwise, that’s really all that you need to know that’s out of the norm. It operates like a typical high end Sony lens and if you’re familiar with those, then you’ll have no issues with this one.
Image Quality
Perhaps my favorite thing about the Viltrox 35mm f1.2 FE Lab is the image quality. The bokeh is nice, the colors are rich, and the sharpness is decent though not as much as it is with the 135mm f1.8. Still, I really like the image quality as it almost reminds me of the older Sony Zeiss lenses. So if you’re into that classic mirrorless camera look, then you’ll want to reach for this. When you use it combined with a flash the image quality becomes even sharper due to how the laws of physics work. But I truly like that this isn’t a terribly clinical lens; though you can tell Viltrox is leaning that way.
Extra Image Samples
The Phoblographer has been huge on transparency with our audience since day one. Nothing from this review is sponsored. Further, many folks will post reviews and show lots of editing in the photos. The problem then becomes that anyone and everyone can do the same thing. They’re not showing what the lens can do. So, we have a section in our Extra Image Samples area to show edited and unedited photos. From this, you can decide for yourself.

May 2026: The N Variant

Viltrox is kind of known for doing some weird things that sometimes end up being cool. I mean, there’s their 28mm f4.5 lens for example. That, to this day, is still one of my absolute favorite lenses for the Sony E mount. But then there are variant lenses: like the new Viltrox 35mm f1.2 FE N.
Why is it called this? Well, they removed the top LCD screen from the lens.
Again, why?
I’m still not sure. Maybe they can’t get access to enough supply of small LCD screens? Maybe folks haven’t discovered gaffers tape. Either way, it’s a variant of the lens available for Sony E mount. And when the unit was revealed to us, we didn’t ask about a Nikon variant.
What I’m about to say, I say with absolute sincerity. It’s really hard to not make good images with the Viltrox 35mm f1.2 lens. I say that as only one of the journalists on this site who has contributed to the review of this lens and its variants. The following images are all straight out of camera JPEGs from the Sony a7r III. The camera has a film profile loaded onto it and I resized the photographs in Capture One. Additionally, Content Credentials are present in the images and you can see them with the right browser settings.
Does the lens still autofocus well? Yes, it will with older camera bodies. And we only found major faults with some of the newer bodies like the Sony a7 V. To clarify that statement, I didn’t test this lens on that body. But instead, it’s more of a general statement.
With that said, no one really has a major reason to upgrade to the latest and greatest Sony cameras. As it is, I think that the Sony a1 II and the Sony a9 III are peak cameras that really can’t be beat. But even then, the Sony a7r III still comes oddly close to them.
One reason why I might seek to get this variant is because of potential battery drain as Sony’s newer cameras have terrible battery life. But otherwise, I didn’t have much of a problem with this lens at all. I set the camera to AF-S for most of the time until I decided to set it to AF-C and human/face and eye detection. It worked fine both ways. But Sony fans will probably engage brainless mode. What’s brainless mode:
- AI human detection
- Aperture priority
- Auto ISO
- Face and eye detection on
- AF-C
Essentially, they make the camera do all the work for them — fundamentally replacing them as photographers for anyone else who can put the camera in their hands.
Let that sink in: I hope that Sony users who pick this lens up use it for it
Nikon Z Varaiant Experience

The autofocus is incredibly quiet. It’s remarkable how quiet autofocus motors are these days when locking onto subjects. For video shooters or anyone who works in quiet environments, this is a blessing. The fact that a lens this large still features a 77 mm filter thread is another pleasant surprise. You do not have to buy massive filter sets or spend ridiculous amounts of money for ND filters. What makes the Viltrox 35mm f1.2 LAB Z mount lens stand out though, is how close it comes to Nikon’s own 35mm f1.2 S while costing significantly less. If you expected a big drop in sharpness or performance, it simply is not the case. Viltrox went ambitious with their LAB series, and it shows in the results.
The image quality is where the Viltrox 35mm f1.2 LAB Z mount lens makes its boldest statement. Wide open at f1.2, it is very sharp. Sharp in a way that makes you blink and check your camera screen again. The center detail at f1.2 is excellent, and the corners clean up quickly as you stop down. When you compare the output to that of the Nikon 35mm f/1.2 S, you begin to wonder how Viltrox managed to achieve this level of performance at a lower cost.
This lens offers rich color rendering. Colors lean towards a natural appearance rather than an overly saturated one. The micro contrast gives depth to faces and objects without making the tones too crunchy. At f1.2 the depth of field falloff is thick and cinematic, something portrait shooters will appreciate immediately. Bokeh is pleasing without being chaotic, and the transition from sharpness to blur is smooth. Backgrounds melt in a way that keeps attention firmly on your subject. This is where having such a wide aperture becomes addictive. You can isolate almost anything with a simple turn of the ring, and with the silent autofocus the lens feels dependable even when shooting moving subjects.

Declaration of Journalistic Intent
The Phoblographer is one of the last standing dedicated photography publications that speaks to both art and tech in our articles. We put declarations up front in our reviews to adhere to journalistic standards that several publications abide by. These help you understand a lot more about what we do:
- At the time of publishing this review, Viltrox is not an advertiser with the Phoblographer. This doesn’t affect our reviews anyway and it never has in our 15 years of publishing our articles. This article is in no way sponsored.
- Note that this isn’t necessarily our final review of the unit. It will be updated, and it’s more of an in-progress review than anything. In fact, almost all our reviews are like this.
- None of the reviews on the Phoblographer are sponsored. That’s against FTC laws and we adhere to them just the same way that newspapers, magazines, and corporate publications do.
- Viltrox sent the unit and accessories to the Phoblographer for review. There was no money exchange between Viltrox and the Phoblographer for this to happen. Viltrox and several other manufacturers trust the Phoblographer’s reviews, as they are incredibly blunt.
- Viltrox knows that they cannot influence the site’s reviews. If we don’t like something or if we have issues with it, we’ll let folks know. We were the first publication to inform about the issue with the Leica M10R and how it renders the color orange. We’ve also called out Sony on several things as well as gone back and changed ratings on products before.
- Viltrox shipped the unit to the Phoblographer and, if they request it back, will be paying for the return shipment. This is a standard practice in the world of journalism.
- The Phoblographer’s standards for reviewing products have become much stricter. After having the world’s largest database of real-world lens reviews, we choose not to review anything we don’t find innovative or unique, and in many cases, products that lack weather resistance.
- In recent years, brands have withheld NDA information from us or stopped working with us because they feel they cannot control our coverage. These days, many brands will not give products to the press unless they get favorable coverage. In other situations, we’ve stopped working with several brands for ethical issues. Either way, we report as honestly and rawly as humanity allows.
- At the time of publishing, the Phoblographer is the only photography publication that is a member of Adobe’s Content Authenticity Initiative. We champion human-made art and are frank with our audience. We are also the only photography publication that labels when an image is edited or not.
