Overview

The Kiron 28mm f/2.8 is a robustly built, compact manual-focus lens with a 7-element design and 55mm filter thread. Optically, it delivers warm, vintage tones and is sharp when stopped down, with minimal vignetting, flare, or chromatic aberration on full-frame; however, it is not razor-sharp wide open. Build quality is solid, but oil on aperture blades is a known issue. It suits travel, street, and documentary photographers seeking a natural perspective and compact setup.
