    Works as it should. All of my EF lenses work with autofocus and IS on my R6. Have tried non canon converter and did nor communicate between lens and camera. Was wast of money

    Works great with my any Canon lens. Unfortunately, the connection isn't great with my Sigma 70-200. This is the only lens I have issues with using the adapter

    Well built accepts Canon EF and EFS lenses for the EOS R. A Must have if you an EOS R Body! RF Lenses are more expensive then EF and EFS allowing you to have a greater variety at a substantial savings.

    I had a large collection of lenses and I was cautious to change systems in anyway, and this adapter is a great way to bridge that with the new Canon R series. It was also part of the initial package with the RP
