The Canon EF-M 11-22mm f/4-5.6 IS STM Lens provides a 35mm equivalent focal length of 18-35mm, and features continuous AF with a built-in STM stepping AF motor to provide smooth, near-silent performance that is especially beneficial to video recording. An Optical Image Stabilizer helps to compensate for up to 3 stops of camera shake, while Dynamic Image Stabilization corrects for a wide range of motion while shooting video.
