SUMMARY
The Viltrox AF 20mm f/2.8 Air lens, one of the most affordable full-frame 20mm autofocus lenses at $168, has been released for L-mount systems. Tested on a Panasonic Lumix S1R Mark II, the lens features a lightweight yet solid build with a metal mount and USB-C port. While its center sharpness is excellent, the corners are soft, and it suffers from significant vignetting and mustache distortion, though it produces good sunstars. The 20mm focal length is noted as a popular choice for modern wide-angle photography and videography.
