Panasonic Lumix G 20mm f/1.7 II Asph. Review

The Panasonic Lumix G 20mm f/1.7 II Asph. is a compact prime lens for Micro Four Thirds cameras, offering a 40mm full-frame equivalent focal length. This second generation model sits in the sweet spot for everyday shooting, street photography, and general walkaround use. The f/1.7 maximum aperture provides solid low-light capability and shallow depth of field for subject separation, while the pancake-style form factor keeps the overall camera system light and portable.

At just under $300, this lens occupies the affordable end of the fast prime category for MFT shooters. The 20mm focal length has long been a staple in the Panasonic lineup, balancing natural perspective with versatility across a range of shooting scenarios from casual portraits to environmental documentation. For creators looking to minimize kit weight without sacrificing aperture speed, this lens delivers a practical compromise between performance and portability.
