The Canon EF-EOS R Mount Adapter lets you use almost any Canon EF or EF-S mount lens on the RF mount Canon EOS R camera body.

This is a simple adapter that contains no optical components, so it maintains the mounted lens’s original optical quality. It also retains the mounted lens’ autofocus and image-stabilization capabilities.

If you’re looking for a more advanced EF to EOS R adapter, we also rent the Canon EF-EOS R Control Ring Mount Adapter that features a customizable control ring.
