Customer Ratings & Reviews

It helped me to used old lenses and buy cheaper lens for my camera.

Works exactly as it should. Allows me to mount all the EF-Glass from my previous Canon camera right onto the R6 without any issues. The only real hitch is if you have any RF glass you'll soon want to upgrade all your EF lenses and scrap the adapter since you won't need it anymore. Simply put...if you have a bunch of EF lenses that you love and plan on holding onto then this adapter is a no brainer if you're upgrading to a mirrorless Canon like I did. If you think you'll be selling off your EF line to upgrade to RF glass then maybe put the $100 you would've spent on the adapter towards a new lens.

After ten years my D40 stopped working and needed a new camera. R100 was fitting my budget but then what about my EF fast lenses I had with D40? Well, this adapter solved that problem. It snaps nicely on R100 and then my EF lenses fit nicely on top of this adapter. I am back in the business with all my previous investment in lenses in tact!

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

Works perfectly for my canon r6 mark II with my 24-70 ef lens! Easy to use and great for transitioning to a mirrorless camera if you still want to keep using your ef lenses! Slides on easily and stays well secured to the camera body. Highly recommended!!

We bought the Canon - EOS R50 4K Video Mirrorless Camera with RF-S18-45mm f/4.5-6.3 IS STM Lens - Black and this was a plus since we had an old canon and wanted to continue using our old lenses.

The adapter has worked perfectly and has met the needs of expanding the availability of use with my new Canon. The store manager was very helpful and led me right to where I needed to go to obtain this item. Overall, the experience with the lens and the store has been excellent.

Works great with my R6 Mk2 and Sigma lens. Does not add too much weight.

It's exactly what I was looking for, very happy with the purchase.

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.

This works great with all of my EF lenses to my R6 MarkII. Using this adapter makes more sense than having to buy a different set of lenses for the new camera. I have not seen any issues so far!

Use the last 30 of canon EF/EF-S lenses on new R cameras. Save money on fancy new lenses if they're too expensive.

great communication and easy purchase. product works great

This was recommended with a zoom lens purchase of EF75-300mm F4-5.6 III Telephoto Zoom Lens for Canon EOS DSLR Cameras - Multi. This adaptor allows the DSLR lens's to fit the new E0S R6's and the models listed above. DSLR lens's are far cheaper than the digital lens's. The price is well worth it for the savings on the DSLR lens's.

Works great with r6 mark ii and my EF lenses. Price is reasonable as well.

Good equipment, nice build quality, solid feel, no noticeable wobble. Would recommend getting the control ring version as I already miss having one on my lens.

Easily attaches my old camera lenses to my new camera!

Ef to rf adapter works great for using ef efs canon lenses or any lense with an ef or efs mount like sigma or tamron on canon r series mirrorless cameras ( r3 r5 r6 r7 r8). The build quality is great and it comes with its own case, saved me lots on buying new rf lenses.

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

Great product enables use of DSLR lenses on Canon EIS R7 mirrorless. Best Buy had it in stock at my local store.
