Canon RF Mount. The Canon RF 800mm f/11 IS STM belongs to Canon’s line of RF-mount lenses. It’s compatible with RF cameras, such as the EOS R, EOS Ra, EOS RP, and EOS R5.

Unique, Compact Super Tele Prime. This lens’s long compact build, retractable design, locking barrel, and fixed f/11 aperture make hand-held super-tele shooting possible. Its aperture also helps provide a balance of sharpness and depth of field.

Distinctive Optical Design. The RF 800’s eight-group/eleven-element design includes gapless dual-layer diffractive optics that help combat chromatic and spherical aberrations while keeping the lens compact and light.

Built-In Autofocus. This lens uses a ring-type Stepping Motor to provide fast, accurate, and nearly silent autofocus performance for both still and video shooters.

Optical Image Stabilization. The RF 800mm f/11’s built-in image stabilizer compensates for four stops of camera shake, so that you can shoot in lower light at slower shutter speeds without worry.

Configurable Control Ring. This RF-mount lens features an 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.

Teleconverter Compatible. The RF 800 is compatible with the Extender RF 1.4x and Extender RF 2x teleconverters, which will extend its focal length to 1120mm or 1600mm, respectively. Both teleconverters are available as separate rental items.
