In this review, we will take an in-depth look at the Viltrox AF 20mm F2.8 FE and how it performs with the Sony A7IV and A7R IV. We will cover its build and image quality, autofocus performance, and overall usability, so you can make an informed decision about adding it to your photographic arsenal.

Viltrox AF 20mm F2.8 FE

Hello my friends, in today’s video we will take a look at Viltrox’s AF 20mm F2.8 FE for Sony E Mount. Viltrox has recently released a couple of lenses intended to provide full-frame results on APS-C. This time, it is the other way around because they are releasing a full-frame lens with an APS-C size. 20mm is a very popular focal length nowadays, and an option to have it in such a tiny and very affordable package is therefore very welcome. In this article, we will take a look at the optical qualities and the feature set of this lens in combination with Sony A7IV and A7R IV to find out whether you should consider getting one.

Focal Length

20mm is quite an interesting focal length by today’s standards. It isn’t extremely wide in comparison to 14 or 16mm focal length, but it puts much less emphasis on the foreground. It is a good compromise between the immersion associated with ultra wide focal length and all-around usability. It is a very useful focal length for landscapes, cities, and architecture. It is also a great focal length for vlogs and capturing the world around you for social media stuff.

Size and Weight

At f/2.8, it is not particularly bright, and it doesn’t offer a lot of subject separation. It is a full-frame f/2.8, though, so it is still pretty bright in the grand scheme of things. The size and the weight are the main highlights of this lens. It is just 5.95 cm long and it weighs 152g. That is incredibly small and light by full-frame standards. Mounted on pretty much any Sony full-frame camera, the size and the dimensions of this lens are pretty much negligible. It will be a particularly great match for Sony A7 Series and the ZV1.

Build Quality

The build quality is okay. The outer construction is plastic, but it doesn’t feel cheap at all. The surface finish is quite nice as well. Unfortunately, it is not weather-sealed. The mount is metal, but there is no weather sealing gasket around the mount. It uses a 52mm filter thread, which is a standard size but you will probably want to buy some step-up rings and use larger filters. A plastic lens hood is included in the box.

Image Quality

I have tested this lens with a fairly demanding 61-megapixel sensor in the Sony A7R IV. The central sharpness is actually excellent right from f/2.8. The contrast is very solid as well, and I don’t really see any diffraction. You will get the same image quality in the center of the frame at f/4, f/5.6, and f/8. The corner sharpness at f/2.8 is not quite as good as the central sharpness but still pretty solid. The contrast is a bit weak, and there is a bit of noise, so I suspect that there is venting compensation going on. The image quality gets a lot better at f/4. The minimum focus distance is very solid though. It can focus as close as 19 cm which translates to 1:7 times magnification that allows you to get a very interesting perspective on close-up subjects.

Autofocus

Regarding autofocus, Viltrox has figured out Sony autofocus a long time ago, so it works as well as with Sony lenses. Besides that, it has a very easy job at this focal length and aperture. It is extremely fast and very accurate with both a7IV and A7R IV. The autofocus is very silent, so it won’t be picked up by in-camera microphone or by a shotgun microphone. The autofocus is not limiting the focusing capabilities of Sony cameras at all, and it works well for both stills and video.

Stabilization

20mm f/2.8 is not stabilized as expected, but the in-body image stabilization in the A7IV or A7R IV is more than sufficient. A little known fact is that if you use active SteadyShot mode, you can get very decent walking performance at 20mm. Static shots, panning, or just pointing the camera around is completely fine as well.

Price and Conclusion

Last but not least, this lens is very affordable. It might be the cheapest autofocus lens that I’ve ever tested. To sum up, Viltrox’s AF 20mm F2.8 FE is a great little ultra wide lens. It provides very solid optical performance and the size, weight, and price ratio is excellent. If you are interested in the 20mm focal length, this is a great option to consider.
