Control Ring

One feature that distinguishes RF lenses from previous Canon lens products is the control ring. The control ring is a feature available on many RF lenses, allowing the user to adjust various settings quickly, utilizing their left hand improving operability.

The RF mount of the EOS R camera body introduced a new 12-pin communication system that improves the coordinated operations between the lens and the camera body. This made it possible to assign various functions to the lens control ring. Aperture, shutter speed, ISO sensitivity, exposure compensation, as well as the AF method, white balance, and picture style can be assigned, selected and adjusted to suit the user's needs. In conjunction with the main dial and quick control dial on the side of the camera body, this new lens control ring offers unprecedented operability. For example, aperture control can be assigned to the lens control ring, while shutter speed and ISO sensitivity can be assigned to the main dial and quick control dial on the camera body. The user can then operate all three controls manually, using the left hand, right index finger, and right thumb, while looking through the viewfinder. The RF control ring is a perfect example of Canon's endless pursuit of the EOS concept of "speed, comfort, and high-quality imaging".
