Overview

The Vivitar 28mm f/2.8 MC (Cosina) is a compact wide-angle lens with close-focus capability. Optically, it is described as a 'little gem', offering good sharpness and contrast for its class. Weaknesses include potential flare and distortion, typical of vintage lenses. Build quality is solid but plasticky, with smooth manual focus. It suits budget-conscious photographers seeking a lightweight, versatile prime for general wide-angle use, especially on film or mirrorless cameras with an adapter.
