Overview

The Kiron 28mm f/2.8 is a robustly built 7-element lens with a minimum focus of 0.30m and 55mm filter thread. It offers a natural perspective with minimal distortion, suitable for travel, street, and documentary photography. Optically, it is sharp when stopped down, with minimal vignetting and chromatic aberration, but soft wide-open. A known issue is oil on aperture blades. It suits photographers seeking a compact, vintage-feel lens for APS-C or full-frame, though the f/2 version may be preferred for the extra stop.
