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