Overview

The Olympus OM-System Zuiko Auto-S 50mm f/1.4 is a well-built, all-metal lens with smooth focusing and a compact design. Optically, it offers good center sharpness wide open, improving when stopped down, but exhibits soft edges, chromatic aberrations, and pronounced flare. Bokeh is pleasing, and the f/1.4 aperture aids low-light shooting. The early 'silver nose' single-coated version is debated among enthusiasts, but differences from later multi-coated versions are minimal. It suits photographers seeking a classic, characterful fast fifty for film or adapted digital use.
