    Overview

    The Panasonic Lumix G 20mm f/1.7 II is a compact pancake lens for Micro Four Thirds, offering excellent center sharpness from f/1.7 to f/5.6 and good edge performance when stopped down. Weaknesses include high vignetting and barrel distortion in RAW, and slow autofocus on some Olympus bodies. Build quality is solid with a metal barrel, but the lens lacks weather sealing and physical controls. It suits street photographers and those prioritizing portability.
