    This adapter allows me to use my EF lenses on my Canon RP. I believe it also supports EF-S lenses. Got it for free with the purchase of the Canon RP.

    Works perfectly. I have a native EF camera body and can't tell a difference in speed when using this adapted on the R. Works perfectly.

    A must have for Canon shooters. Allows you the option of using your current and favorite lenses seamlessly. Easy on. Easy off. 2 other versions are available. One has a programable control ring. And a pretty cool version with removable filters that are fit behind the lens. Far less chance of scratching. But costly. The basic adapter is all you need. Simple and useful.
