Customer Ratings & Reviews

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.

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.

Easily attaches my old camera lenses to my new camera!

This works great and allows me to use my older Canon lenses. I have so many lenses I have two of these to use with both my mirror-less cameras. Easy to use.

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.

I love this adapter I can use all my lenses on my new rp camera and it’s the best thing I ever bought!!!

Exactly what we needed. High quality lens adapter that works exactly as intended

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

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.

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.

One of the best purchases I have ever made. I use this product 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.

Super easy. Doesn’t take up a lot of space. I was surprised to find it also comes with its own little case to keep it in when you’re not using it too!

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

Fit perfect and easy to use so i am able to use all my cannon lenses

Great add on I was afraid of purchasing the new camera because all the lens I already have. The lens adapter worked great. I can use all my old lens without any problem.

I use with my 100-400 II and have shot tennis with no issues, in fact it is way better than my 5d3 as I can now select where I want to focus anywhere in the frame! Now Canon just needs to come out with a professional R based camera that can shoot at a higher frame rate, but overall very happy with the performance.

This is a great product, and the shipping is always great as well!
