The Canon EF-EOS R Control Ring Mount Adapter lets you use almost any Canon EF or EF-S mount lens on RF mount camera bodies. It’s a simple adapter that contains no optical components, so it maintains the mounted lens’s original optical quality. It also retains the mounted lens’s autofocus and image-stabilization capabilities.
Like the native RF-mount lenses, it includes a customizable control ring that you can use to adjust a range of exposure settings, including ISO, aperture, and exposure compensation. If you are just wanting a basic EF to EOS R adapter, we also rent the Canon EF-EOS R Mount Adapter.
