Characterized by a truly thin profile, along with an advanced autofocus motor, the EF-S 24mm f/2.8 STM Lens from Canon is a wide-angle prime designed for APS-C-size EOS DSLRs. Providing a 38mm-equivalent focal length, this lens takes on a slightly wider-than-normal perspective to benefit its use in a broad variety of shooting situations. A stepping motor AF system pairs well with cameras featuring the Movie Servo AF mode, where it will deliver fast, smooth, and nearly silent focusing performance that can instantly be manually overridden at any time. When coupled with a sophisticated optical design, this slim, lightweight, and versatile lens is an ideal take-everywhere option.
