Canon Mount Adapter EF-EOS R

Achieve the absolute pinnacle of lens adaptation performance with the Canon Mount Adapter EF-EOS R. Positioned as a crown jewel of the full-frame mirrorless EOS R system, this legendary L-series tier utility is meticulously designed for uncompromising image quality. Featuring an ultra-bright glassless interior pass-through, it grants you breathtaking control over depth of field, rendering an exceptionally thin focal plane paired with dreamlike background bokeh for peerless subject isolation when using your favorite legacy glass.

To combat optical aberrations that often plague poorly engineered adapters, Canon incorporated a sophisticated interior matte black baffling system, virtually eliminating internal reflections and color fringing even when shooting wide open. Powered by a heavy-duty electronic communication pipeline, it tracks eyes and faces with precision when using USM and STM legacy autofocus systems. Complete with pro-grade weather sealing and a durable metal construction, it is built to endure demanding studio and field environments.
