Viltrox AF 35mm f/1.2 LAB FE: one-minute review
Professional lenses typically offer the best image and build quality, but at a cost. Plus, when thinking about features on prime lenses, most are fairly straightforward despite the aforementioned characteristics. One of two lenses bucking this trend is the Viltrox AF 35mm f/1.2 LAB FE, the other being the Viltrox AF 135mm f/1.8 lens.
The latter is available for both Sony E and Nikon Z mount, with the 35mm soon to be available for Z mount, too. The thing I love about these lenses is that, despite being primes they’re surprisingly feature-packed, and are available at extremely attractive prices.
The 35mm f/1.2 LAB costs just $999 / £959 at Amazon, which is an amazing price for what you get (if you’re buying from Australia you can purchase the lens in USD.) This price is especially impressive when the slower Sony FE 35mm f/1.4GM is considerably more expensive. The Sony is, of course, a flagship G Master lens, which may suggest superiority, but the 35mm f/1.2 LAB holds up well by comparison.
That extra 1/3 stop of light-gathering capability makes a difference in two ways. First, it makes the lens better for astrophotography. Second, it produces a beautifully shallow depth of field. Detail is also impressively sharp wide open at f/1.2, so for portraiture and astrophotography this is a truly stunning lens.

Viltrox AF 35mm f/1.2 LAB FE: Design
- Digital color screen
- Large and heavy for a 35mm lens
- Excellent build with weather sealing
Most prime lenses are fairly simple in their design, relying on their fast maximum apertures and excellent image quality to act as the main selling points. The 35mm f/1.2 LAB certainly follows suit here, but it also has a few tricks up its sleeve that set it apart from other primes. It’s also a beast of a lens, at 3.51 x 8.80 inches / 89.2 x 121.8mm and weighing32.5oz / 920g.
It’s certainly nowhere near as large and heavy as the 135mm f/1.8 LAB lens, but it’s close to double the weight of the Sony FE 35mm f/1.4GM and is slightly larger. The fact that it’s an f/1.2 lens is a contributing factor, but Viltrox LAB series lenses do seem to be pretty hefty, to say the least.
Both lenses are made of aerospace-grade magnesium-aluminum alloy with a die-coating, so they have a premium look and feel alongside being of an extremely high build quality. Plus, the lenses feature a dust and moisture-resistant construction, making them perfect for outdoor photographers.
The filter thread is 77mm, so not too large and ideal for both circular and square filters, while the 11-blade aperture produces smooth bokeh with circular highlights. The minimum focusing distance is 13.4 inches / 34cm, which isn’t the shortest you’ll find but is still pretty good.

As mentioned, despite being a prime lens, the 35mm f/1.2 LAB is fairly feature-packed. It has a customizable multi-function ring, which by default is set to control the aperture, with clicked and clickless operation selectable using a switch.
There are also two customizable Fn buttons and a small color digital screen that shows the focus distance, aperture, and the active Fn button. The screen can, alongside the Fn and multi-function ring, be customized by connecting the lens via Bluetooth to the Viltrox Lens app.
Since this is a third-party lens, firmware updates and customization can’t be applied in the same way as OEM lenses. But, with the lens unattached from a camera, it can be powered via a USB-C port on the lens mount and then connected to the app. This works incredibly well; a firmware update was required during testing and only took a few minutes to complete.
The ability to personalize the controls is extremely useful for tailoring the lens to the way you like to shoot. I was quite happy with the default configurations, so although I looked at the options available in the app, I left everything as it was.
Viltrox AF 35mm f/1.2 LAB FE: Performance
- Excellent image quality overall
- Impressive sharpness at f/1.2
- Sharpest at f/8
The image quality produced by this lens is sensational, with incredible sharpness and detail wide open at f/1.2. Sure, with this lens you’ll need to stop down on some occasions, but most people want a lens like this for that fast maximum aperture, and the 35mm f/1.2 LAB is incredible when shooting wide open. It’s not perfect, but it’s seriously impressive.
The 35mm f/1.2 LAB produces exceptional center sharpness at f/1.2, and while extreme corner sharpness is quite soft, edge sharpness is excellent. Corner sharpness increases gradually as you get closer to the center of the frame and as you stop down the aperture, with f/4 showing greatly improved extreme corner sharpness.
Overall sharpness continues to improve up to f/8, which, like many lenses, is the sweet spot at which most detail is resolved and the overall image produced is sharpest. Beyond f/8, diffraction begins to come into play, with f/11 providing slightly less sharp images, and f/16 exhibiting the least sharp results.

Vignetting is most visible at f/1.2 as you’d expect, and becomes less noticeable until f/2, where it almost disappears, and completely disappears at f/2.8. This is normal for a prime lens, and it’s not an issue at all because vignetting is easy to remove with software.
There isn’t a profile available in Adobe Lightroom yet since this lens is still relatively new after an April 2025 release, so any corrections currently have to be made manually. Chromatic aberration is minimal, with only the tiniest amount of fringing visible, and this was easily removed.
Autofocus performance is fast and precise, with the lens locking onto subjects quickly and silently. The AF 35mm f/1.2 LAB features Quad Viltrox HyperVCM motors, which Viltrox claims provide 150% faster AF than STM motors. I couldn’t perceive a difference in speed.
The lens also supports subject recognition, which I tested by using people/eye recognition to shoot portraits wide open. This worked exceptionally well, with perfectly sharp eyes and a dramatic fall-off in depth of field.

How I tested the Viltrox AF 35mm f/1.2 LAB FE
- I tested it over several weeks
- I used it to capture multiple subjects
- I tested it with an unforgiving Sony A7R V
I tested the Viltrox AF 35mm f/1.2 LAB FE over several weeks attached to an unforgiving Sony A7R V, shooting a range of relevant subjects and using different aperture settings to test sharpness and distortion. I shot both static and moving subjects to test autofocus performance.
With 30 years of photographic experience and 17 years working as a photography journalist, I’ve used many of the cameras and lenses that have been released in that time. As a working photographer, I aim to test cameras and lenses from a photographer’s point of view.
