    • Perfect fit for my new camera R5
Ordered new EF-EOS adapter it was opened and missing and with wrong back cap on the back instead of RF back cap it had EF probably the one who had it put the wrong cap adapter itself was fine and looked like new, returned and asked for a replacement, it came few days later that was new as it should with the correct adapter rear cap for RF and little bag for ef adapter itslef and brand new very happy with it, test it wil all my EF lenses it worked great, fast autofocus, compatible with my sigma 35 mm and 70-200 plus all EF canon lenses, its a great option so I dont need to buy other RF lenses. The only downsize i would say is that is made in Taiwan, I wish it was made in Japan since they tend to have higher quality but still under Canon so it should be ok. Make sure once you order to have all accessories since some are returns even though they advertise as new, make sure you have EF front cap with canon sign and RF back cap so it will fit when you pack, as well should have am adapter bag wraped in plaastic with canon manual and USA warranty on it, if you find all these you are good to go. Dont buy other adapters this is kind of cheap and is good quality and value using it with your EF lenses. Highly Recommended ... show more

    • Works well with Canon EOS RP
It works well with my EOS rp camera to both canon ef 24-105mm f/3.5-5.6 (AF) and samyang 135mm f/2 (also ef mount, but Manual Focus). It is also built sturdy and feels like a quality product.

    • Perfect
This is a perfect adapter to enable the use of Canon EF lenses on a Canon RF mirrorless camera. No loss of functionality whatsoever.

    • Great subsitute for RF lenses.
You know when a piece of equipment is great when you don't have to think about it. I bought a Canon R7 but had many expensive EF lenses and did not want to go through the expense of buying new glass. This adapter worked great saving me a ton of money and the hassle of completely replacing my photography kit. ... show more

    • Best of the three Canon adaptor versions IMO! And cheapest!
Review Image by Destiny Marie Destiny Marie
I just upgraded to an R6ii from a 5Diii, and needed this adaptor to use my EF-L lenses with the new camera. I was nervous my lenses would have a loss in quality, but on the contrary they are actually performing better than ever. A lot of that has to do with the camera, because the R6ii is incredibly fast, but it's amazing to have an adaptor that gives no loss in quality and just flawlessly connects the EF lenses to the R system. I have had ZERO issues with connection, everything connects just like a lens connects straight to the camera. I have two L lenses, so I just keep the adaptor on the camera body and swap out the lenses to the adaptor as if they were connecting straight to the camera. The adaptor does add length, obviously, but the weight isn't that significant. If you're like me and have a heavy 70-200 lens, it works perfectly, but because of the extra length on an already long and heavy lens, I am careful when carrying because I don't want it just dangling on the adaptor/camera. The adaptor does connect tightly with no wiggle though, so it is safe if you do let the camera hang to your side with the lens, I'd just take precaution. Better to be safe than sorry. Honestly, I couldn't be happier. For the price, this is truly a great deal. $100 to make my expensive L lenses work with the new camera? Perfect! Definitely beats having to upgrade to even more expensive lenses right now. I did a lot of research on the three different Canon brand adaptors, and out of the three, this one was the best choice for me and was the cheapest as well which was a plus! If you're on the fence between the three different adaptors, I'd really recommend this one. Unless you really need an extra control ring (that's awkwardly placed), or drop in filters (that are very expensive), this is such a great price and works flawlessly! ... show more
