Canon EF-EOS R Mount Adapter Ring with Control Ring

The Canon EF-EOS R Mount Adapter Ring with Control Ring offers the same lens mount conversion as the EF-EOS R Mount Adapter, but also includes an objective control ring. Customizable and easy to access without looking away from your camera, allowing you to set tactile manual control among other settings. Programmable controls: The objective control ring can be programmed via the camera menu to adjust various settings like aperture, shutter speed, ISO sensitivity, and exposure compensation. Intuitive touch manipulation: The objective control ring is easily accessible, providing tactile feedback in thirds or halves of a stop (can be disabled through a Canon special service for filmmakers who prefer a smoother experience).
