Canon EF-S 24mm f/2.8 STM Lens 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.
One aspherical element of Canon EF-S 24mm f/2.8 STM Lens is incorporated within the lens' construction, which helps to minimize chromatic aberrations and produce imagery with notable sharpness and clarity. Optimized lens coatings further benefit performance by reducing lens flare and ghosting for increased contrast and color fidelity. Additionally, similar to the STM AF system, the aperture mechanism is based on a micro-stepping motor to maintain overall quietness during operation. Optimized lens coatings and design help to suppress lens flare and ghosting for increased contrast and clarity. A nearly circular seven-bladed diaphragm contributes to a pleasing out-of-focus quality when utilizing selective focus techniques. Slim-profiled lens, measuring less than 1"-thick, is an ideal everyday lens for a wide variety of shooting applications.
