20mm · f/1.7
The Panasonic 20mm F1.7 II is a compact pancake lens for Micro Four Thirds, offering excellent center sharpness and a bright f/1.7 aperture. However, it suffers from slow autofocus on some Olympus bodies, noticeable chromatic aberration, and high vignetting wide open. Build quality is solid with a metal barrel, but bokeh can be distracting. It suits street photographers and those prioritizing a small kit.
