    I have some older canon lenses that I was afraid I’d never be able to use again. This adapter makes it so Easy to change lenses and use my older lenses.

    A great tool to be able to use my old EF lens on my new Canon R5. No issues so far, and super easy to mount and use with my older lens. Most importantly, I've experienced no lag with autofocus controls when using the adapter,

    This is a must have if you do not have the cash for RF lens, which are expensive. The EFVlens works great. can not wait to get new RF lens. I shot a reception with EF 24-70. Great pics.
