    • 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

Ive had this adapter for a few years now and it is sturdy and does its job. If it wasnt for this mount I wouldnt be able to use my EF mounts

    • Works great to allow use of lens collection on new camera.
If you are coming from an old Canon like I did, this will save you a ton of money! Good glass ain’t cheap and works just as well with the adapter. Went I upgraded from an SL2 to an RP this was the only way I could justify it I’m my head to make sense.

    • It fits perectly, works perfectly.
Great adapter. All features of the camera and lenses work seamless and perfectly. I can still use all my EF and EF-S lenses on my new pair of R8's. The missing star on value is because Canon is always overpriced on new stuff. Hence my using the EF lenses I already own.

    • Seamless operation, lends new life to my EF lenses
Switching to mirrorless doesn't mean you have to toss your EF lenses. I don't notice any degradation of operation, and AF is sharp. I'll get some RF lenses eventually, but right now with my R7 (and soon-to-be-acquired R5) I've got all the glass I need.

    • Works as advertised
I was dubious that it would control all of the features on my older lenses, but it works well.
