Canon Control Ring EF-EOS R Lens Adapter is a unique lens adapter designed for attaching any EF or EF-S-mount lens to the EOS R mirrorless digital camera. This sophisticated adapter incorporates a customizable Control Ring, the same as that on native RF-mount lenses, for intuitively adjusting exposure settings, such as ISO, aperture, and exposure compensation. This ring provides tactile feedback when being turned, making it easy to recognize and control your settings adjustments. Like EF-EOS R lens adapter, currently it is out of stock everywhere.
