Compact 800mm super-telephoto

The Canon RF 800mm f/11 IS STM is a fixed-aperture super-telephoto lens built for the RF mount. Its retractable locking barrel keeps the profile short when stowed, making it far easier to carry than conventional 800mm designs. Gapless dual-layer diffractive optics suppress chromatic aberration for clean detail. Optical image stabilization provides up to 4 stops of shake correction.

For reach-focused shooters.

Wildlife and sports photographers who need extreme reach in a light package will appreciate the portability. The fixed f/11 aperture means exposure stays constant through the zoom range, simplifying long-distance work. Photographers who need wide apertures for subject separation, faster shutter speeds in dim light, or very shallow depth of field should consider faster alternatives.

800mm reach with 4-stop stabilization headroom

The 800mm focal length brings distant subjects close, and the 4-stop stabilizer lets you shoot handheld at slower speeds than usual for this focal length. The fixed f/11 aperture limits low-light headroom and background blur, so the lens runs out of flexibility in dark conditions or when creative isolation is the priority. Extender compatibility adds reach when conditions allow.

Questions about this item

Which Canon camera body must I already own to mount this RF-mount 800mm f/11 lens?

You need a full-frame Canon EOS R-series body with an RF mount; the lens will not fit EF, EF-S or EF-M cameras without an adapter.

How does the fixed f/11 aperture affect autofocus when I keep using my older EF lenses via an adapter?

The lens itself maintains its f/11 aperture; adapted EF lenses keep their own maximum apertures, so autofocus performance on those lenses is unchanged.

How can I confirm the optical stabiliser is delivering the rated 4-stop correction after I attach the lens?

Enable IS in the camera menu, half-press the shutter at 800mm and watch the viewfinder — the image should steady noticeably compared with IS off.
