Professional 400mm f/2.8 super-telephoto lens

The Canon RF 400mm f/2.8 L IS USM is a high-performance super-telephoto lens built exclusively for EOS R-series cameras. It delivers the same optical formula as the respected EF 400mm f/2.8L IS III USM. Professional sports and wildlife photographers gain a wide f/2.8 aperture for shallow depth of field and fast shutter speeds in demanding light.

RF mount limits adapter options

The RF mount design means this lens mounts natively only on EOS R mirrorless bodies; it cannot be used directly on EF or EF-S DSLRs. Autofocus and image stabilisation rely on camera-body communication specific to the RF protocol. The 52 millimeter filter thread accepts drop-in filters rather than front-threaded types, so existing front filters cannot be attached.

Replaces EF 400mm f/2.8L IS III for mirrorless users

Photographers moving from the EF 400mm f/2.8L IS III to an R-system body gain native RF mount communication without an adapter. The jump is worth it when you need the optical stabilisation’s 5.5 stops of correction and three IS modes working directly with in-body systems. It is not for shooters who remain on DSLR bodies or who need focal lengths beyond 400mm without adding the compatible 1.4x or 2x extenders.
