EF-EOS M2

I probably would have purchased the Canon version for my new R6, however it was unavailable and I needed it sooner. I ordered this one thinking I could always return it if needed. Glad to say that it works great and so will be a keeper. I find it to have a solid feel with all of my glass and hasn't malfunctioned at all. I don't have any RF lens yet so can't compare, but the auto focus is super fast with my Canon 70-200 2.8. When I tried an EF-S lens, it worked fine and the R6 automatically set it to a 1.6 crop.

I bought this adapter primarily to use my Tamron AF 70-300 lens with a Canon RP camera, and I'm pleased to say that it works great. Considering its reasonable price, it's definitely a worthwhile purchase.

I am happy with this. It adds a little bit of weight to the camera but it allows me to use lenses I already had and lenses that aren’t available for the digital mirror camera I recently got. Would recommend for sure.

So far, I've used this for the 4 EF lenses I have for my M50, and it works great. It definitely encourages me to explore more EF and EF-S lenses to add to my collection.

Adapter had been working on, albeit not a perfect seal on the lens side. Fine on body. I don’t think it leaked light. Got on photo shoot and all of a sudden it stopped communicating with camera. Turns out the little mount that comes on the adapter is very fragile and if it gets pushed upward, even less than 1/2 millimeter, it loses contact. Now this was fixable, just removed it and it worked fine. But then i went to zoom, spin the barrel of the attached lens and the lens isn’t even attached. The lens lock has come loose and no longer locked lens in place. I did t damage the adapter at all. It has only been in a camera bag 2x in the past year. Almost a complete disaster if it wasn’t for gaff tape…

I believe I ordered the wrong mount...this one doesn't fit my GH5...I believe Amazon shows the reviews for a number of these similar items from the same brand, which is why I brought it,not paying attention to the difference in 2 and II ...I also brought it cause it said $156,vs the $218 one I believe I should have brought...if you canon M's I believe it works...but I need the one with II on it for the Panasonic GH5

Purchased for my EOS R. I didnt want to shell out the $2700 bucks for the rf 70-200 L series. I decided to give this adapter a shot with an EF 70-200 F4L and it works flawlessly. At half the price of the Canon adapter I was worried about quality, but no complaints so far.

This jus does not fit well on my EOS RP. I can move it a lot after it is "locked" on to my camera bodyUpdate it is so loose now I lose communication with camera.VERY DISAPPOINTEDUpdate. I found the problem , I ended up buying the Canon so I figured I had nothing to lose when I try to fix it. You can clearly see how lose one screw is in one pic. The other three were all finger tight. I took them out put some loctite on the threads, screwed them down and now works perfectly. I think whoever put this together never tightened the screws.
