K&F Concept EF-EOS R AF – Canon EF Lens to Canon RF Mount Adapter

The K&F Concept EF-EOS R adapter lets you mount Canon EF/EF-S-mount lenses on Canon RF-mount (EOS R) cameras. Gold-plated electronic contacts retain autofocus, aperture control from the camera body, IS lens image stabilisation and EXIF data recording. A detachable tripod foot with a 1/4"-20 thread takes the load off the mount when working with heavier lenses.

Autofocus and aperture control

The EF-EOS R adapter connects Canon EF/EF-S-mount lenses to Canon RF-mount (EOS R) cameras. Gold-plated electronic contacts ensure reliable signal transmission between lens and body: autofocus is fast and accurate, you set the aperture directly from the camera, and EXIF data is recorded in your images.

Image stabilisation and tripod foot

The adapter supports optical image stabilisation of IS lenses, which you will appreciate especially in low light. The tripod foot underneath has a 1/4"-20 thread for a quick-release plate or tripod head and can be removed.

Adapter construction

The contacts are metal, the mount leaf springs are stainless steel and the interior has a matte finish that suppresses light reflections. The lens is released with a button on the adapter.

Compatible cameras

The adapter is designed for Canon RF-mount (EOS R) cameras, for example Canon EOS R3, R5, R5 C, R6, R6 Mark II, R7, R10, R50, R100, RP.

Before you order

You will find the mount type of your lens and camera in their manuals or in the technical specifications on the manufacturer's website. The EF-EOS R adapter is designed for a Canon EF / EF-S lens on a Canon RF (EOS R) camera.
