    • 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

    • Great fit
I did a little research on my camera and this was recommended. Easy to use and a good 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.

    • 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

If you have an EOS camera and you want to use other lens then you need this. Works great

    • A must-have for EF lens owners
If you're like me and have finally made the switch from mirrored to mirrorless, then this is what you need. Instead of shelling out extra money for lenses that you already have just to have the new R mount, you can reuse your likely still great glass on your shiny new camera. For most applications (i.e. the average hobbyist) you'll likely never notice the difference between your previous lenses versus the more expensive R lenses, so it just makes more sense financially to get this adapter and utilize your current glass collection. ... show more

    • Work on EOS R5
I finally upgraded my old EOS 5D MKIII (still have for aurora pictures BTW) and bought this so I didn't have to buy ALL new lenses. My old Canon EF USM IS II 70-200mm and my 600mm lens work on the new R5 with this adapter. I'll upgrade lenses eventually but new lenses are roughly the price of my first car :-) ... show more
