Canon is gradually rolling out some very impressive lenses in the new EOS RF lens mount but full frame Canon mirrorless body owners can already make good use of the strong line-up of EF and EF-S lenses thanks to the Canon Control Ring Mount Adapter EF-EOS R. Compatible with everything from monster telephotos to ultrawide tilt-shift tools (and even APS-C coverage EF-S optics) the Control Ring Mount Adapter EF-EOS R expands options while mainting full compatibility and functionality. It allows entry to Canon's mirrorless future without having to leave behind many of the world's best lenses.
