Canon RF Mount. The Canon RF 15-35mm f/2.8L IS belongs to Canon’s line of RF-mount lenses. It’s compatible with RF cameras, such as the EOS R and EOS RP.

Versatile Wide-Angle Zoom. This lens’s wide-angle focal-length range makes it great for a range of applications, including landscape and documentary photography, while its 11-inch minimum focusing distance is quite nice for close-up work. The fast f/2.8 aperture and rounded nine-blade diaphragm offer shallow depth-of-field capability and enable shooting in difficult light.

Advanced Optics. This lens’s twelve-group/sixteen-element optical formula includes two Ultra-Low Dispersion elements and three aspherical elements that minimize chromatic aberrations and color fringing while providing high clarity, color fidelity, and sharpness. Canon has applied an Air Sphere Coating to the lens elements to combat flare and ghosting.

Optical Image Stabilization. The RF 15-35mm f/2.8L IS’s built-in image stabilizer compensates for five stops of camera shake, so that you can shoot in lower light at slower shutter speeds without worry.

Nano USM Autofocus System. This lens uses a ring-type Ultrasonic Motor and an STM mechanism to provide fast, accurate, and nearly silent autofocus performance for both still and video shooters. You also get full-time manual-focus override for precision adjustments when working in one-shot autofocus mode.

Configurable Control Ring. This L-series lens features a new integrated, configurable control ring that you can use to adjust a range of exposure settings, including ISO, aperture, and exposure compensation.

High-Quality Build. This lens boasts a weather-resistant build that protects against the elements so you can use it in adverse conditions.
