Overview

The Chinon 28mm f/2.8 Auto is a compact, well-built manual focus lens with smooth handling. Optically, it offers very good central sharpness from f/2.8 to f/11, but edges are soft wide open, improving to good at f/8. Chromatic aberration is high at edges, and barrel distortion measures -1.72%. Bokeh is attractive, flare control impressive, and vignetting notable at f/2.8. It suits enthusiasts seeking a vintage look on mirrorless or film cameras, especially for street and travel.
