Canon Mount Adapter EF - EOS R, Compatible with EOS RP, EOS R, EOS R6, EOS R5

I’ve been using the Canon EOS to RF lens converter (EF-EOS R Mount Adapter) for a several months now, and it’s been an absolute blessing. As someone with a collection of high-quality EF glass, I wasn’t ready to part with my lenses when upgrading to a mirrorless camera (and I mean buying all new mirrorless lenses to replace them would be pretty pricy). This adapter made it so I didn’t have to!!The adapter works seamlessly. There’s no noticeable loss in image quality, autofocus remains fast and accurate, and all lens functions seem to carry right over . Using the old lenses on an mirrorless is actually a bit of an unexpected treat with the advanced functions of the newer camera. The only con I have is that it adds a bit of length to the build but otherwise totally worth the reasonable price.

Using on an R6 with multiple zoom and prime lenses and everything works perfect, focus just as fast and accurate. Only tried with Canaon lenses

exactly as advertised

Adapted all my Canon L Glass to a new Canon Mirrorless.. Works Great ! Saved me a ton of money too.

This review is for "Canon Mount Adapter EF - EOS R, Compatible with EOS RP, EOS R, EOS R6, EOS R5"It works flawlessly with all my Canon EF lenses, old or new! I'm using it with new Canon EOS R7.At $200 plus tax, it's more expensive than the cheapest adapter that can do a similar job but without the control ring. There is a Canon brand adapter at $100 without the control ring. Canon Brand adapters, while it is the best guarantee for the maximum compatibility with Canon lenses (I don't own anything other than lenses) they are about double the price of the after market adapters out there.

Works as expected

Works great for my 70-200 2.8 Like but not 24-105 L-- it fits but the lens is dark

No speed or imagine quality degradation that I can notice. Fits snug and has a satisfying click when attached just wish it wasn't so expensive, but at least you can feel the quality
