Canon Mount Adapter EF-EOS R, Black

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!

Works great to transfer my EF lens onto my mirrorless camera. It has contacts so my lens motors work for AF.

I recently bought a lens for my Canon R7 without realizing it wasn’t compatible — rookie mistake. Thankfully, this Canon EF-EOS R adapter saved the day. Once I attached it, the lens worked flawlessly, with fast autofocus and full functionality. The build quality is solid, and it feels like a native part of the camera once mounted. No lag, no issues, just smooth performance. If you’re transitioning to the R series and want to keep using your EF lenses, this is a must-have. 10/10 — highly recommended!

Had an off brand adapter that worked fine between my old EF lens and my R8 just to try it. But, before my trip to France I bought an EF 70-300 IS II USM for my R8 and bought this to make absolutely sure I would not have any adapter problems ruining my photos. It works. And though it is more expensive that the off brands, the peace of mind was worth it to me.

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

I was gifted a Canon R7 mirrorless camera and have a lot of EF lenses. This is a great adapter to allow me to use my pre-existing lenses on the new camera body. It fits perfectly, it is seamless and easy to use. Picture quality has been excellent and it is a good size that is not too bulky. For the price, it adds a great value for what I have already. Autofocus is quick and the weight is minimal. I am very pleased with its performance.

Works well and does it's job. Fitting is a bit tighter than it should be but it works.

This adapter is one of those pieces of gear you slap on, use for a week, and stop thinking about entirely, which is honestly the best compliment. It feels sturdy, locks in with a satisfying click, and your EF lenses just… work. Autofocus behaves like it always did (sometimes even better on newer R bodies), stabilization is fine, and image quality is untouched since there’s no glass inside. The only time you really notice it is when the setup gets a little longer and front-heavy with bigger lenses, and yeah, paying this much for what’s basically a well-made spacer can sting. Occasionally an older lens might hunt a bit in dim light, but it’s rare and usually not a dealbreaker. If you already own EF lenses and are moving to EOS R, this adapter doesn’t feel like a compromise, it feels like Canon quietly letting you keep your old gear without drama.

Perfectly working

Great way to keep using ef lenses on rf body. No issues at all.

No issues at all the EF lens have super quick focus photos are spot on dont hesitate to buy

Muy buen producto

Der Adapter ist gut. Leider habe ich eine Canon eos r mit objektiv bestellt (siehe Produkt Beschreibung)und dann diesen Adapter erhalten. Ich habe alles telefonisch klären können aber ärgerlich ist es trotzdem
