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.‎

One aspherical element 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.‎

Compact wide‎-angle prime is designed specifically for use with APS‎-C‎-sized sensors‎,‎ and will provide a 35mm‎-equivalent focal length of 38mm‎.‎ An STM stepping motor is incorporated into the lens‎'‎ design to provide quick‎,‎ smooth‎,‎ and near silent autofocus performance‎.‎ Additionally‎,‎ this focusing mechanism also pairs well with EOS cameras featuring the Movie Servo AF mode to enable continuous focusing performance when working in live view‎.‎ Converse to the AF system‎,‎ full‎-time manual focus override is possible when in One Shot AF mode for critical fine‎-tuning of focus placement‎.‎ One aspherical element is incorporated within the lens‎'‎ design to minimize chromatic aberrations and distortions from edge‎-to‎-edge‎.‎ Optimized lens coatings and design help to suppress lens flare and ghosting for increased contrast and clarity‎.‎ A micro‎-stepping mechanism is employed to deliver near silent aperture adjustment‎.‎ 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.‎
