Canon Control Ring Mount Adapter EF-EOS R

There's been a lot of buzz surrounding the release of Canon's first full-frame mirrorless camera. Canon has already released a handful of high-quality RF-mount lenses for the EOS R , but if you already shoot with a Canon DSLR, you don't have to wait for more lens options to max out this camera's imaging potential. This low-profile mount adapter lets you keep using your existing EF and EF-S lenses with full functionality. The camera even recognizes when you attach an EF-S lens and will crop your images accordingly. Canon's RF lenses have a cool extra feature that their DSLR lenses lack — a control ring on the barrel that lets you make quick adjustments to settings like aperture, shutter speed, exposure compensation, and more. This mount adapter adds the control ring to your EF and EF-S lenses.
