Customers are saying

Customers are enthusiastic about the EF-EOS R5, EOS R6, EOS R, and EOS RP Lens Mount Adapter for its compatibility with a wide range of EF lenses, ease of use, and affordability. It allows photographers to continue using their existing EF lenses on their new mirrorless cameras, saving them money and preserving their investment. The build quality is solid, and the adapter works flawlessly, delivering sharp images without vignetting. While some customers find the control ring unnecessary, the overall consensus is that this adapter is a must-have accessory for photographers who want to use their EF lenses on their EOS R series cameras.

    When getting the Canon R8, I was a bit worried about using the less expensive EF lenses and possibly losing features. I first bought this adapter and after getting some amazing shots, found that you can have you cake (an amazing full frame camera) and eat it too (take advantage of lower price of the older EF lenses on the market) and get some amazing shots!

    A must have if you plan to invest in the mirrorless EOS R. This adaptor allows you use your existing lenses rather than investing in the new RF mount lenses. Without this adaptor I would not have been able to make the switch to mirrorless. It was offered free with the EOS R at the time of purchase. It adds a little length to the lens, but I hardly even notice the adaptor is on the camera. Highly recommended!

    Worth it to give you range into other bodies, focus might not be as good but I think its amazing to use other 3rd party lenses or old EF mount lenses

    Great for EF lenses use on RF mount cameras, I use two Tamron G2 series (24-70mm/70-200mm both f2.8) on a Canon EOS R they work just as intended. Lense stabilization and autofocus works normally.

    Nice if you have some EF lenses or want to save some money by purchasing EF lenses. Auto focus and stabilization still works as expected.

    This adapter allows an EF lens to mount on the Canon EOS R series bodies. It does not have the control ring, but that’s not an issue at all for me. There are other brands of mount adapters available, but I’ve read they’re not as dependable as the native Canon brand.

    I upgraded my camera to R7 and I have a few lenses for my older camera and I just did not want to buy new lenses unless I really have to. I am glad for this adapter, it works great, it adds a bit of weight since it is between the camera and the lens but I am happy to keep my previous lenses and they work great. I did buy new lenses but I have both older and newer for now. I am happy I can use both. very useful.

    I have spent years accumulating some nice canon L series glass and this allows me to use it with my new R6 mk ii. Wish i would have made the switch years ago.

    Got this free with my Canon RP. I use this to adapt my EF 75-300 and my EF 100mm 2.8 macro lens. Works great. All functions like AF and metering work great in my Canon RP

    The new mount of the EOS R requires this interface to use traditional Canon lenses. Beautifully designed and functionally outstanding. Works well with my telescope t-ring too.
