FROM THE MANUFACTURER EF-S 24MM F/2.8 STM Incredibly lightweight, the EF-S 24mm f/2.8 STM is a fast and versatile lens with advanced AF and superior optics. With a 35mm equivalent focal length of 38mm, it's appropriate for a variety of purposes. The lens features optimized lens element placement and includes an aspheric element for high image quality from the center of the composition to the corners, and has specialized coatings on the lens elements to reduce ghosting and flare. To ensure excellent color balance, a 7-blade circular aperture provides superb out-of-focus detail. The EF-S 24mm f/2.8 STM excels during movie shooting thanks to its STM motor that enables silent and smooth focus tracking (on EOS cameras with Movie Servo AF), plus a micro-stepping drive that keeps aperture changes quiet. The lens also offers full-time manual focus, manual AF adjustment (one-shot AF), and can focus down to a minimum distance of 0.5 ft. (0.16m). Delivering optical brilliance in a lightweight and unobtrusive construction, the EF-S 24mm f/2.8 STM is a great fixed-optical length lens for photographers looking to add a travel-friendly option to their collection.
