The Canon EF-M 22mm f2 STM lens is a pancake lens designed for use with the Canon EOS M compact system camera. This EF-M Mount lens is a great travel lens ideal for a wide range of subjects and offers a maximum f/2.0 aperture to ensure stills and movies can be captured handheld even in low light. Whether you're shooting landscapes or portraits, the Canon 22mm lens is a great all-around travel companion and features a minimum focusing distance of 0.15m.
Focusing is smooth and quiet with Movie Servo AF, which uses STM stepping-motor technology, a great incentive for video enthusiasts looking to capture professional looking videos. This fast, pancake lens is extremely light and compact yet still provides you with the high-performance and image quality you would expect a Canon lens to produce. For use with the Canon EOS M and not suitable for DSLRs with Canon's EF or EF-S mounts.
Canon's STM lenses
Canon's new line of STM (stepping motor) lenses are specifically designed for shooting video with Canon's DSLRs that feature Movie Servo AF mode, such as the EOS 650D, 700D, 70D and 100D DSLR cameras. The auto focus (AF) system has been specically optimised to ensure fast, accurate and silent operation for video work. The result is a movie that sounds professional without the sound of the noisy AF motor in the background.
