The Canon RF 800mm f/11 IS STM is a uniquely compact super-telephoto prime lens designed for full-frame Canon RF-mount mirrorless cameras. Combining an extreme 800mm focal length with a retractable, locking barrel and a fixed f/11 aperture, it delivers impressive reach in a surprisingly portable form factor, making handheld super-telephoto shooting a practical option.

Long reach, compact handling

Thanks to its retractable and extendable design, the RF 800mm f/11 IS STM remains impressively compact when not in use. The fixed f/11 aperture plays a key role in keeping the lens lightweight and well balanced, while maintaining a reliable mix of depth of field and sharpness for distant subjects.

Advanced optics for clarity and control

The optical design features gapless dual-layer diffractive optics, which help significantly reduce chromatic and spherical aberrations while contributing to the lens’s compact size. An Optical Image Stabilizer provides up to four stops of shake correction, helping you achieve sharper results when shooting handheld, in low light, or at slower shutter speeds.

Smooth, quiet autofocus

An STM stepping motor delivers fast, smooth and near-silent autofocus performance, making the lens well suited to both still photography and video recording. Full-time manual focus override allows for precise fine-tuning when needed.

Customisable control and extender compatibility

A configurable Control Ring lets you adjust key exposure settings such as aperture, ISO and exposure compensation directly from the lens. The RF 800mm f/11 IS STM is also compatible with Canon RF 1.4x and RF 2x extenders, allowing you to extend your effective focal length even further while retaining RF system functionality.
