Overview

The OM System 20mm F1.4 Pro is a compact, weather-sealed prime (40mm equivalent) with excellent center sharpness from f/1.4, though edge resolution is weak until stopped down. It offers fast, silent autofocus and fine optics, but some purple fringing is present. Build quality is robust and lightweight, though the lens hood feels cheap and there is no manual focus clutch. It suits street, documentary, and travel photographers seeking a portable, fast prime, especially those invested in Micro Four Thirds.
