When mounted onto a Canon camera with an APS-C sized sensor the field of view is equivalent to a focal length of about 60mm in 35mm format. The Canon EF 40mm f2.8 comes in a portable, lightweight package and is suitable for a wide variety of subjects, from discreet portraits to landscapes.

- STM - Canon's new 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.
