Product Details

  • Maintains AF and Image Stabilization
  • Configurable Control Ring

Programme this lens control ring to adjust aperture, shutter speed, ISO or exposure compensation while your EOS R-System camera is still at your eye

Control Ring Mount Adapter EF-EOS R offers the same lens mount conversion as Mount Adapter EF-EOS R, but also adds a Lens Control Ring. The ring is customisable and easy to find without taking the camera from your eye offering tactile manual control over various settings.

Customisable functionality

The Lens Control Ring can be programmed via the camera’s menu to adjust various settings such as aperture, shutter speed, ISO sensitivity and exposure compensation.

Tactile, intuitive handling

It’s easy to find the Lens Control Ring without taking the camera away from your eye. Gentle clicks give a tactile feedback in thirds or halves of a stop (and can be removed via a special Canon service for filmmakers wanting smoother operation).

Product Reviews


Does what it says on the tin!

Great feature being able to set the ring for exposure compensation love it for birds in flight

This product works perfectly with all my L-series lenses. The R6 camera is smaller than the 5D it replaces but the lenses are longer because of the adapter. Personally I like this because it makes the camera balance nicely in the hand. I'm still learning how to use the control ring and haven't decided what adjustment to allocate to it but it is useful because it is easily useable whilst looking through the viewfinder and half pressing the shutter button.

Having switched to a mirrorless camera after 20 years of Pro DSLR and owning........a few EF lenses, a mount adapter is THE must have item. I like the customisable control ring function and for the time being, set it for Aperture on the R6. Feels like I’ve gone full circle back to my very first T70 with an FD 50mm in the late 80’s!!
