EF-M22mm f/2.0 STM

The EF-M22mm f/2.0 STM is a lightweight “pancake” lens that maintains its compactness when mounted on the EOS M; sliding effortlessly into most pockets. The lens has a diameter of 60.9mm, thickness of 23.7mm and a mass of 105g. It uses the 1 GMo aspheric lens to ensure high-quality images with high levels of image resolution and contrast in the periphery when at extreme close-up. A new type of stepping motor was developed to enable quiet and smooth Movie Servo AF when used with the EOS M.
