Canon RF 800mm f/11 IS STM Lens with UV Filter and Cap Keeper

Canon RF 800mm f/11 IS STM Lens

This super-telephoto prime is built for full-frame Canon RF-mount mirrorless cameras. Its retractable design and fixed f/11 aperture create a compact form factor that makes handheld shooting at 800mm practical. Four stop-effective optical image stabilization assists sharp results in difficult lighting. The STM stepping motor provides quick, quiet autofocus for stills and video.

Fixed f/11 aperture and retractable design

The fixed f/11 aperture is the single specification that defines this lens's character. It enables the slim, lightweight profile but does not open wider, so low-light work relies on higher ISO or the built-in stabilization. Buyers who need a faster maximum aperture for shallow depth of field or dim interiors cannot use this model. The retractable barrel must be extended before shooting, adding a step to the workflow.

UV Filter, Cap Keeper and Cleaning Kit

The bundled UV filter protects the front element from dust and scratches without affecting exposure. The lens cap keeper secures the cap to the strap or barrel, reducing the chance of loss during fast handling. The cleaning kit lets you maintain optical clarity in the field. No additional accessories such as extenders or tripod collars are included.
