Work's perfectly for my eos r7 and my ef 24-105mm. Ive loved it so far!

Having the EF 70-200 F2.8 II IS USM and the EF 100 F2.8 Macro IS USM I needed this adapter to pair it with my R8. It works and the photos I have taken thanks to this adapter are crisp and clean

Works as intended and good build quality. Was able to pick it up on time.

Adapter works way better then expected. Thought it would be a horrible experience like adapters are with sony mirrorless. However this adapter makes canon ef glass focus just as fast as native rf lenses do from the lenses I've tested. This also makes ef lenses focus faster on the rp then canons DSLR in my experience. Highly recommend this adapter.

This adapter works great, so of the cheaper 3rd party adapters don't fit as well, it's worth the extra few dollars for the Canon brand adapter

Perfect for using non RF lenses on a mirror less from Canon. Works seamlessly and is perfectly compatible. I’m currusing this mount to connect my non RF prime lens 50mm to my R8 and the results are great.

I returned this only because I found the one that was lost… someone found it and turned it into the venues lost and found. But I use this adapter for the EF 135mm that isn’t on RF yet. I’ve tried other 3rd party brands and it’s not worth it.

Purchased to run EF mount Sigma lenses on my RP and it works as intended while being relatively small. Has an easy switch to detach the mounted lens and haven't experienced any quality issues.

This is PERFECT for my older lenses. I did not have to buy the rediculous priced RF lenses and my old lenses work even better with this adaprot and the R8

I am so happy that this is a thing. I had a EF telephoto lens (that was very expensive) left from an old camera that I had sold. I wanted to upgrade to a mirrorless camera but a comparable lens would have been an additional $2500. For $100 this ring allows me to use my EF lens on my RP camera and it works great.

These are in short supply at least in early 2021. Make sure you have a reliable line on one if you expect to use your R-mount camera with older lenses, otherwise you'll be like me with a very expensive brick waiting for the adapter to arrive so you can start taking pictures! I paid for expedited shipping and Best Buy waited 2 weeks to ship it anyway. But that's a comment on Best Buy and not the item. The adapter is sturdy- I've been using it with a 150-600mm lens and no droop or light leaks. The only reason I give it "Average" value is because there are no optics in it, it is just a spacer for the EF lenses with electrical pass-through and no particular weather sealing. But once you drop $2k on a camera I guess canon figures you won't blink at $100 for an adapter like this.

I had to buy this mount to be able to use my collection of EF lenses when I bought the R5. Compared to the RF counterpart lens that I have tried and experimented, personally the EF+mount combination is not as good in many fronts. Having made the switch to mirrorless, I don't think I would ever go back to DSLR, so eventually I would be looking into slowly replacing into RF lenses. For anyone who is deeply invested in EF lenses like myself, this is of course a quick and cheap solution for the mirrorless transition, but if not, I would consider purchasing RF lenses even though they are almost twice as expensive as their EF counterparts.

I just transitioned from the Canon M5 mirrorless to the Canon RP, so this works great with the lenses I currently own. No need to purchase any new R lenses.

Works great! Thanks for the awesome service! This adapter was a seamless transition from one lens to my others and fit camera perfect!

best investment when switching to mirrorless and looking to save money to purchase future RF lenses. $100 gets you running on mirrorless bodies with an ROI that can be made back in one shoot, as well as potentially save you money for future purchases until you're fully transitioned over.

I sold my Canon EOS 60D and two lenses to get this and the EOS RP. I have two other lenses that I absolutely love to use and I'm not done with them. The fact that this came with the camera was amazing. I can still use my DSLR lenses with my mirrorless camera until I get the correct mirrorless lenses to replace those two.

Very high quality converter. I am so glad I found this item as now I no longer have to invest over a $2,000 In a new mirroless lens. 10/10

Haven't used much but works as expected when needed

Works flawlessly, double the price of third party adapters a safe voice.

must have for ef lens and highly recommend native brand
