Viltrox AF 40mm f/2.5 FE 40mm
Weighing just 167g, this full-frame 40mm f/2.5 prime stands out for its exceptional portability without sacrificing a bright aperture or weather-sealed build. The STM motor delivers quick, quiet autofocus, while the optical design with one ED and one aspherical element controls aberrations in a compact package. This lens is best for street and travel photographers who prioritize a lightweight, discreet setup on Sony E-mount bodies.
