Overview

The Nikon Nikkor 28mm f/2 Ai is a manual-focus lens praised for its sharp center performance at all apertures, though corners are soft wide open due to spherical aberration. It exhibits typical barrel distortion for a wide-angle. Build quality is excellent, with sturdy metal construction and a smooth focus ring. The lens is compact and handles well, but its depth-of-field scale is narrow. It suits photographers who value fast aperture and classic build, especially for general use or demanding environments.
