Customer Ratings & Reviews

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.

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.

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.

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.

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

Great product. It was compatible with my canon eos rp.

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

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.

Works just as expected. Great RF body to EF lens adapter. Use it with my 24-105 f/4 and 70-200 f/2.8 and both work great!

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.

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

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

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.

Must have if you have a collection of regular DSLR lenses.

Necessary equipment if you have an R camera and want to use with RF lenses. So much better than investing in new R lenses. I have used with both telephoto and macro lenses without any issues.

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.

Allows you to use EF lenses on mirrorless R system. Your lenses will feel upgraded and easy to use. If you are financially ready to upgrade to RF lenses then this unit is a no brained.

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

Great product works amazing with my R6 markII and issues on the photos while using the ef lenses
