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.

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.

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

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

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.

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

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

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

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.

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

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.

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

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.

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

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.

Great adaptor, did what i needed it to. I had a bunch of old lenses and so this helped alot.

Was exactly what i was looking for to be able to use old EF lenses on the new R6 mark II with the new RF style lense adapter

Works as advertised and allows you to use your old lenses!
