Canon Mount Adapter EF-EOS R

Canon Mount Adapter EF-EOS R

The standard Mount Adapter EF-EOS R allows EF-S and EF lenses to be used on EOS R cameras seamlessly. Photographers who already have a collection of EF-S or EF optics can invest in the EOS R System confidently, knowing their existing lenses will work as expected.

Bring your EF-S lenses to the EOS R System

EF-S lenses are designed for APS-C sensor EOS DSLRs, but they can also be used on EOS R cameras via adapter. The camera will automatically produce cropped 11.6-megapixel images that match the smaller image circle of EF-S optics.

Built to last

EOS R adapters are built to withstand professional use, with metal mounts on the front and back. They are also weather-sealed against dust and moisture, so you can keep shooting even in tough conditions.

Designed to perform

Expect your lenses to behave in the same way as they do on EOS DSLRs, turning in the same great performance with the same high quality.

Engineering excellence

Canon engineers developed the EOS R System adapters to maintain compatibility, quality and performance when connecting the EOS R to existing EF and EF-S lenses.
