CANON ADAPTER RING EF - EOS R

Connect your EOS R system to the world of EF and EF-S lenses

EOS R system adaptor rings offer full compatibility with the entire range of Canon EF and EF-S lenses, enabling EOS R owners who also own an EOS camera to integrate seamlessly with their current lenses;

Take your EF-S lenses on the EOS R system

EF-S lenses are designed for EOS SLRs with APS-C sensors, but can also be used on EOS R cameras such as EOS R. The camera will automatically produce cropped images of 11.6 million pixels, corresponding to the smallest image circle of EF-S lenses.

Built to last

EOS R adapter rings are designed to withstand professional use, thanks to their metal mounts on the front and back. They're also dust- and moisture-proof, so you can capture your scenes even in the toughest conditions.

Built for performance

Expect your lenses to work just as they do with EOS SLRs: the same outstanding performance and superior quality.

Designing excellence

Canon engineers have developed EOS R system adapter rings to maintain compatibility, quality and performance when connecting the EOS R to existing EF and EF-S lenses.
