Introduction
The APS-C 35mm focal length is equivalent to 52mm on a Fullframe camera, therefore it is in the ‘standard’ focal length category and very close to the classic 50mm lenses on fullframe cameras, with an angle of view offering none of the ‘perspective distortion’ associated with wide angle or telephoto lenses. This lens on an APS-C camera is equivalent to a Nifty Fifty on a fullframe camera. Let’s have a closer look at it!
I tested this lens on a 26 Mp Fujifilm X-S10.

Handling and Build Quality
This autofocus lens features a sleek, minimalist design with no external controls apart from the manual focus ring. It is compact and lightweight, weighing only 179 g, making it an excellent match for smaller camera bodies. In the following picture you can see it next to the TTArtisan 35mm f/1.8, which I liked a lot when I reviewed it and I still like it but it is slightly larger than this Viltrox, otherwise the exterior build, look, and design are very similar.
The focus ring is relatively large and metallic, and, like all Fujifilm lenses, it controls focusing electronically. Turning the ring quickly results in significant focus shifts, while slower movements allow for more precise adjustments. It employs internal focusing, so the lens’s length remains constant when focusing, and the front element does not rotate.
The lens body is made of hard plastic, while the mounting plate is metallic. The mounting plate includes electronic pins for data communication, enabling autofocus, aperture control via the camera, and transmitting EXIF data. Additionally, there is a USB-C port on the mounting plate for firmware updates.
All the markings on the lens are printed, which contributes to the plasticky feel of the build. The lens comes with standard plastic rear and front caps, as well as a plastic snap on lens hood.
This lens lacks built-in image stabilization. While the autofocus is accurate, its speed on my Fujifilm X-S10 is unremarkable. That said, Fujifilm cameras are generally not known for blazing-fast autofocus, and the X-S10 is among the slower models in their lineup. Even so, the autofocus is sufficiently fast for typical day-to-day photography.
Optical Features
There have been a few lenses from China with outstanding MTF charts lately and this is the latest one. Such a theoretical performance could only be seen from high end and very expensive Japanese or German lenses in the past but now with computer aided lens design the Chinese seem to catch up in the theoretical design when it comes to sharpness and some of the aberrations at least. Let’s have a look in practice.
Sharpness (Infinity)
For the infinity sharpness test, we look at three areas of the image, centre, mid-frame, and corner, see highlighted areas in the image below!
Well here we can see that the practice matches the theoretical curves as the sharpness is top notch. The lens is very sharp from wide open at f/1.7 in all areas. Corners are generally not as excellent as the centre and midframe but the they are very sharp and we can see diffraction makes the lens a little less sharp at f/11 and a little more at f/16.
Sharpness (Portrait)
Let’s look at the points of interest for portraits at the portrait distance: the very centre, the centre’s inner periphery (1/3 rule intersection), and the centre’s outer periphery (1/4th intersection).
At portrait distance the centre and the inner circle are very good to excellent, but the outer circle just good. Closing the aperture just one stop and you get excellent sharpness at all three tested points.
Sharpness (Close-up)
The closeup sharpness is very good wide open and becomes excellent by stopping down. Peak performance at f/4, after which the diffraction makes the lens less sharp. Nevertheless, it is a very good performance.
Lens Distortion
There is a mild pincushion distortion visible in the pictures.
Vignetting
High vignetting wide open at f/1.7, which improves to moderate vignetting at f/2.5. It becomes very low at f/3.5 and negligible at f/4 and smaller apertures.
- F/1.7: 2.4 EV
- F/2.5: 1.3 EV
- F/3.6: 1.0 EV
- F/5.0: 0.8 EV
- F/7.1: 0.8 EV
Focus Shift & Aberrations
The longitudinal chromatic aberration is quite well controlled. There is a slight negligible color fringing wide open at f/1.7, which practically goes away at f/2.8.
The Lateral chromatic aberration control is flawless as no LaCA is visible.
Flare Resistance
You can make any lens look bad in this category if you try hard and long. This Viltrox lens though, shows solid resistance against veiling flare as the contrast in the image is good almost irrespective where the sun is in the frame. On the other hand it can show some ghosting at both larger and smaller apertures in certain situations. Overall, I rate it better than average for its price class, offering decent performance for a budget-friendly option.
Coma
A small amount of coma is visible in the corners of the image when shooting wide open at f/1.7. Most of it disappears by f/2.8, where it becomes negligible, and by f/4, it is completely gone.
Sunstars
Sunstars can be produced by this lens but only at f/16, otherwise I would not rate them as very well. Only at f/16 the sunstars become somewhat distinct, but far from the best ones we have seen.
Focus Breathing
The lens exhibits a moderate performance here as we see some focus breathing. It is not very bad though.
Bokeh
The bokeh highlights exhibit distinct onion-ring patterns due to the presence of an aspherical element in the lens. Toward the edges and corners of the frame, the highlights take on a cat’s-eye shape, which is not unusual. In addition to that, some hard, double-edged bokeh highlights appear, especially towards the corners, which may negatively affect the overall rendering in those areas.
At close distances, the bokeh is very soft—again, not uncommon—especially considering the lens’s minimum focusing distance, which is an impressive 0.33 m for a 50mm full-frame equivalent. In the following images, you can see how the background blur is rendered at different distances from the subject. For each image, I stepped back approximately 40–50 cm, starting from minimum focusing distance.
As expected, the background blur becomes somewhat busy at mid to long distances. While not overly distracting, it is not among the most pleasing blurs available. Here there are a few more examples and you can see even more among the sample images.
Conclusion
| I LIKE | AVERAGE | I DON’T LIKE |
| Sharpness Size and weight Price Chromatic aberrations Bokeh (-) |
Lens distortion Vignetting Coma Build Sunstars (-) Flare resistance (-) Focus breathing (-) |
This is an exceptionally sharp lens, among the best in its class. Its compact size and lightweight design are highly appreciated, especially on smaller camera bodies. The excellent control of chromatic aberrations is also noteworthy. While some aspects, such as distortion, vignetting, coma, sunstars, and focus breathing could be improved, they are not significant issues. As shown in the table above, there’s really nothing to dislike, though not everything is top-notch. Considering its price and affordability, this lens offers great value for money and is likely to satisfy the majority of enthusiasts. Are you on a budget or want to spend your money on more than only one single lens, have a closer look at this lens and you hardly become disappointed. If you’re on a budget or want to get more value from your investment, take a closer look at this lens—you’ll likely be very satisfied.
