The Viltrox AF 25mm f/1.7 AIR is a compact, featherweight APS-C prime lens designed for street and general photography. It features a fast f/1.7 aperture, 12 elements in 10 groups, and a 52mm filter thread. The lens delivers very good image quality, quick autofocus, and smooth bokeh, with minimal color fringing and slight barrel distortion. Build quality is robust for the price, with a hardened aluminum mount and USB-C port for firmware updates. Not weather-sealed and lacks an aperture ring or AF/MF switch, but offers outstanding value and portability.
