Overview

The Olympus Zuiko Digital 25mm f/2.8 pancake lens is exceptionally compact and lightweight, ideal for portable setups with Olympus E-4xx cameras. Optically, it delivers very sharp results from f/2.8 to f/11, with best sharpness at f/4. Chromatic aberration is well controlled at wider apertures but increases when stopped down. Corner shading is noticeable at f/2.8 (2/3 stop) but diminishes by f/5.6. Distortion is moderate (0.3% average) but easily correctable. Build quality is solid with a metal mount and smooth focusing ring, though mostly plastic. Bokeh can show concentric rings on point light sources. It suits photographers seeking a compact, affordable standard prime for everyday snapshots and travel.
