Canon's STM lenses Canon's line of STM (stepping motor) lenses are specifically designed for shooting video with the camera's Movie Servo AF mode. The first STM lens was released along with the Canon EOS 650D and has been designed to work with the 650D's AF so that they're fast, accurate and silent. The result is a movie that sounds professional without the sound of the noisy AF motor in the background.
