Excellent Canon EF To EOS R with Control Ring
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 perfectly
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

Great Quality, But Overkill for My Needs
In my opinion, the configurable control ring is overrated. Any basic adapter would probably get the job done just as well for my needs. Since switching to mirrorless, Iâve been buying RF lenses and only have one EF lens left, so I donât plan to purchase more EF glass.That said, the product is exactly as described, and Canonâs build quality is excellent. If youâre willing to pay the premium price, this is the best option out there. For those who heavily rely on EF lenses, itâs definitely worth considering.

Canon Ring Mount Adapter EF-EOS R
Recently, I purchased the Canon EOS R50 Camera for my birthday. I have owned the Canon Rebel t3i and t7i for several years but I wanted a less heavier camera since I do not always like using a iPhone for taking pictures, buying the control ring is an added luxury. I am not a professional photographer but since I have retired it’s just a hobby and fun for me to do something else while out and about other than sit with a crochet hook or knitting needles with my hands in motion working a a scarf while in public. The control ring works as described I am happy with my purchase and to be an option that is compatible with Canon.

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

Sharpness and Smooth operation
I’m loving my EF series lenses. I see no pressing reason to upgrade to the R type lenses. This thing on the Canon R6 Mark II has made me very pleased. I just shot a baby shower and the vast majority of the pictures were usable. Meaning Clear and sharp. Adds about 3/4’s of an inch to your lens length but even so would not hesitate to recommend.

I decided to go with the Canon made adapter as I was hearing about either loose or too tight connection to lenses with third party ones, the control ring works really well adding an extra control dail at my finger tips (use for ISO), no issues with focus or image stablisation with the lens, I only have one issue and that is the price for offical Canon products, but that is the camera world.
