Customer Ratings & Reviews

I have a couple of these that I just leave on my older EF lenses. Works great on EOS R and R5 cameras.

Great adapter, priced ok easy to snap in and use..

Fits great, was worried about getting a 3rd party model from fears that they would be loose. Makes using my EF lenses a breeze, and I don't have to get rid of all my old lenses. No speed issues, in fact a couple of lenses actually seem to perform faster. Best buy purchase was easy, arrived in reasonable amount of time considering Covid shipping issues.

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.

Works exactly as expected. No setup or any configuration, just install it and it works. Lets you use your existing EF lenses just like you are used to.

Good adapter to use ef and ef-s lenses on RF Cameras. Auto focus quick

I was hearing mixed reviews of people using this adapter with their EF canon lenses - but you literally cannot tell a difference in the quality! Save yourself money and keep your old lenses and use this bad boy. It's perfect and will get you those high quality lens shots even if they aren't RF lenses. The price is great too in my opinion - also, just get this one instead of any knock offs.

I placed this adapter on my 500mm mkll and attached my r6 and the adaptation began. Great experience, works as described. I couldn’t ask for anything better to combine my new camera to an ef lens. Focus is fast and spot on. This adapter fit both camera and lens perfectly. Canon hit this one out of the park.

Just upgraded to a new Canon R series mirrorleas camera and have a bunch of EF mounts. Good news, you can save money on buying RF mount lens with this adapter. Doesn’t effect the pictures you take one bit.

great product, easy to use, prevented me from having to buy a brand new lens when i switched cameras

There's always the temptation to buy the third party brand items but Ive never had a problem when buying authentic Canon and this item has been no different.

I am using for my new EOS r6 mark ii. My older lens works perfect without any hassle. Autofocus works well too and fits well. No complaints!

? 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.

Allows us to use our old lenses so we’re happy. The added length isn’t an issue. This allows us to consider other EF lenses like the zoom lenses that are cheaper than their RF counterparts.

ACTIVELY use this on the daily, I own a Canon EOS R10 camera and this allows me to use older lenses. This is perfect.

The adapter is easy to put on the camera and it works well. There is no noticeable weight or length added.

I was a bit skeptical about the compatibility issues that I may face due to the adopter, but as of now even after 6 months of use, never encountered any flaws, except one or twice there was an random error message while using SD card from Sony camera i remember. Well worth, so i do not need to buy all set of new lenses.

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.

I recently purchased the Canon EF-EOS lens adapter, and overall, it delivers solid performance for photographers looking to use existing Canon lenses with their new mirrorless line. Build and Design: The adapter is nice and solid, with a metal construction that gives confidence in long-term durability. Mounting it is straightforward, and it locks securely with a satisfying click. It’s compact enough that it doesn’t add excessive bulk to the camera setup. It even comes with a nice carrying case. Performance: Autofocus works reliably with most existing lenses. Image stabilization is generally maintained, which is great for handheld shooting. I didn’t notice any degradation in image quality, and the adapter preserves full electronic communication between the camera and lens. Compatibility: The adapter is compatible with a wide range of EF and EF-S lenses, making it highly versatile. For Canon users transitioning to EOS mirrorless cameras, the EF-EOS lens adapter is practically essential. It allows you to leverage your existing EF lens collection without compromising performance. While not perfect for every lens, its versatility and reliability make it a worthwhile investment for both enthusiasts and professionals. A must-have if you are moving from a traditional DSLR to a mirrorless camera.
