Great product allowing me to use all my lenses Tamron or Canon on My New Canon 6d r Camera, No light is lost I don't notice a weight difference..Well worth the price

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!

Super easy to attach to my canon r6 mark ii. Plan on buying RF lenses but this is a great way to save money for now. Fits greats and holds all my lenses well. Love the case it comes with too.

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!

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.

This adapter saved me lots of money by allowing me to use my Canon lenses and I didn't have to purchase new ones for my new mirrorless camera!

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 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.

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.

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

This is my first EF-to-RF adapter. This adapter does it's job, Works perfectly. Work for my Sigma 18-250mm F3.5-6.3 DC Macro OS HSM. very shap for my RP.

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.

Great buy to add versatile use of lenses already purchased and allow you to continue to use them on upgraded camera without breaking the bank to buy all new lenses

Makes my older Canon lenses work with my new EOS R6 saving me more money for my future RF lenses.

This Canon adapter is a must for using an ef lens on an R system

We had a fantastic experience in the Midland, Tx store. The guy working in the camera Department was extremely helpful and knowledgeable. We are very happy with our purchase!

Great makes it easy for switching lens from my Rebel T7 to my EOS R6!

Perfect to be able to allow me to use any camera lens with my canon without having to buy expensive ones.
