Overview

The Olympus G.Zuiko 50mm f/1.4 Auto-S is a fast, well-built lens with smooth focusing and a solid metal construction. Optically, it offers good center sharpness wide open and excellent stopped down, but suffers from chromatic aberrations, edge softness at large apertures, and pronounced flare. The single-coated chrome-nose version is often debated against later multi-coated models, though differences are minimal. It suits photographers seeking a characterful, fast normal lens for low-light or portraits, especially on film or adapted to digital.
