Overview

The Canon EF-M 22mm f/2 STM is a compact pancake lens praised for excellent sharpness, contrast, and low chromatic aberrations. OpticalLimits notes it performs well wide open. Weaknesses include slow autofocus and a plastic interior despite a metal barrel. Its lightweight, solid build suits the EOS-M system. Best for street, casual, and social media photography, it offers a 35mm equivalent field of view at an affordable price.
