Overview

The Olympus M.Zuiko 25mm f/1.8 is a compact, lightweight prime lens for Micro Four Thirds, offering a 50mm equivalent field of view. Optically, it delivers excellent center sharpness wide open, with good borders and corners, though slight corner softness and minor chromatic aberration are noted. Vignetting is moderate at f/1.8 but reduces on stopping down. Build quality uses high-quality plastic with a metal mount; the included hood is a plus. Autofocus is fast and silent. It suits photographers seeking a versatile, affordable standard lens for everyday use, though depth-of-field is limited compared to full-frame.
