Canon EF-M 22mm f/2 STM

The most iconic lens in the EF-M system — Canon's 22mm f/2 STM pancake delivers a natural 35mm full-frame equivalent field of view in a body so compact it barely extends beyond the camera mount. At f/2 it offers genuine low-light capability for an EF-M prime, and the STM motor provides smooth, near-silent autofocus well suited to video. On any EOS M-series camera it transforms the body into an exceptionally pocketable street and travel kit. Exclusively for Canon EF-M mount cameras.

GearFrame's Take

The EF-M system's defining lens — a 35mm-equivalent pancake that makes any EOS M camera genuinely pocketable without sacrificing a fast f/2 aperture.
