Customer Ratings & Reviews

Works as advertised. Lets me use my ef/ef-s lenses on my new R10 with no issues.

Does exactly what's needed. I haven't had any connection issues that I've had with 3rd party lens adapters in the past. The AF on my EF lenses are even faster on the R5 than on the 5D.

Exactly as described, and works great. No problems!

This is a must have for anyone planning on getting a EOS R-series camera. If you already have Canon lenses, this will let you use all of them on your new body. If you don't have any previous Canon lenses, this will give you a much greater variety of lenses to choose from, instead of just the expensive R lenses. The supply of these has been limited at times, so if you see it available, get it.

Great adapter to use multiple lenses must get for your professional or recreational uses!

The Canon EF-EOS RP Lens Mount Adapter works as advertised. I have been able to use all of the EF-S lenses from my previous camera. The auto focus works; the auto exposure works. If you're upgrading to a new Canon R or RP camera and have Canon lenses from your previous Canon camera that were EF or EF-S you will definitely want this adapter.

Having the EF 70-200 F2.8 II IS USM and the EF 100 F2.8 Macro IS USM I needed this adapter to pair it with my R8. It works and the photos I have taken thanks to this adapter are crisp and clean

This is top tier product for your cannon camera I recommend this product for your lens

I recently purchased a Canon EOS-R. This is new Canon R Series and that built for canon RF series lenses. But People like me who already invested in EF lenses need this adopter so we can use our EF series lenses on Canon EOS-R. Working for me. I almost use my 24-70 mm, 70-200mm & 85mm with this adapter & it works just fine.

Seemless transition for using ef lenses on rf mount. Only caveat is it adds length and cumbersomeness to the camera/lens combo and its awkward to change if you change lenses a lot. Either get two or seriously consider an rf lens upgrade.

Not much to say other than it is a great bridge from DSLR to Mirrorless or EF glass to RF Body. If you are looking to get a Canon mirrorless FF camera and already have EF glass this is a must-have. There are other versions of this but I have not retreated not buying the one with an extra ring or the drop-in filter.

It works as advertised. Allows me to easily use my EF lenses on my RF mount camera bodies without sacrificing any quality or functionality of the original lens.

Work's perfectly for my eos r7 and my ef 24-105mm. Ive loved it so far!

This adapter gives new life to your old EF lenses. On a mirrorless system the auto focus works even faster than before. RF lenses are limited and expensive. The adapter is the perfect solution until the next RF lens comes along.

A must if you plan to use your ef canon lenses on the new eos r series canon cameras . Planing to purchase canon mirror less camera . It’s hard to purchase as it is always not in stock at BB . Just always look on line for availability , as they sell fast . As online reviews stated this is the best adaptor to the eos r series cameras .

This item was needed and a great purchase as i have older lenses.

works great! I was worried it wouldn't be the same shooting with an adapter, but I haven't had any issues and I've done multiple shoots with it.

Works flawlessly, double the price of third party adapters a safe voice.

Works as intended and good build quality. Was able to pick it up on time.

It works good, it’s just a little frustrating I have to buy multiple pieces just to put my nice lens on my new camera. I wish the lens worked for all canon cameras. Now it’s just super bulky, the lens I have is a 24-70mm so it’s already a big lens, now this adds more weight.
