Customer Ratings & Reviews

Works great with EF lens, allows all functions of my older lens on my new canon R8 work without issue. Worth the purchase.

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.

Worked perfect. Helped me accomplish the transition with my camera.

If you are looking to use your old EF-S lenses on a new mirrorless camera, then this product is for you. However, with my experience, I am limited to a Crop Scenor frame for each EF-S lens when using it on my mirrorless full frame camera. Overall, product still works great and can ebe used for a variety of situations.

Works flawlessly eith my Canon R50! I bought it for an EF lense and all the features and functions worked and the photos have been amazing.

This adaptor works great with my EF lenses. Quality product, would not go with any other brand.

Works well, although I wish I had purchased the version with the adjustment ring for added features, this one does the job well.

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.

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.

This item works so seamlessly. Saves $$ from having to buy the R lens immediately.

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.

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 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.

Fits perfectly and now I can use the EF lenses that have been collecting dust for years.

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.

? Works really Well, I placed a ? Mark only because you Have to have this Adapter for your EF lenses to Work. Overall it works great, looks good on camera. love the idea that the EOS R is the Future of Canon Camera's. Cant wait till price comes down on RF Lenses. Would love to own one. Little Pricey for me at the moment.

Great option for all your lenses. Too bad is not included free with the camera but, still a great option.

I love that I got to keep my EF lenses. This adapter is all you need. It's easy to put on and easy to remove. I looked at the two other adapters and settled on this one. I don't use filters and three different wheels control the ISO, shutter speed and f stop. Very happy with my choice.

I bought EOS R as want to try mirror less. But lenses are expensive. This is a life saver as I use my existing EF lenses with switches RF.

Just what I was looking for. Recently purchased a R7 and wanted to be able to continue using T7 lens.
