Canon 2971C005 Bayonet adapter EF-EOS R. , black

Excellent adapter that works exactly as expected. It allows my Canon EF lenses to mount seamlessly on my EOS R camera with no noticeable loss in autofocus speed, image quality, or functionality. The build quality is solid, fits securely on both the camera and lens, and feels like a genuine part of the system. If you're moving from a Canon DSLR to the EOS R series and want to keep using your EF lenses, this adapter is a great investment.

Worked well. Worked ok on my tamron len . Plus my other canon lenses although it did not work too well on my 100-300mm lens. But personally I think it is very good and worth the money.

Perfect, everything works on camera as it should. Reasonable price so I thought I'd get the canon rather than a 3rd party. Only buy it once so get the best.

I've just bought a canon R7 to replace my old Canon 7d. The EF to RF adaptor is required to allow my old lenses to work on the new camera. The adaptor fits and works perfectly with no noticeable affect on picture quality. The adaptor arrived when amazon said it would and I wouldn't hesitate to buy again.

Bought the adapter after upgrading to a new Canon R7. Had EF-S and EF Canon lenses. All work perfectly well. The adapter feels well made and fits the camera and lenses well with a solid fit. Would recommend the Canon version to ensure full compatibility and communication between the camera and body electrics.

More expensive than look a likes. But works perfectly and enables use of Canon EF/S lenses with Canon mirror less cameras ROS R. Some say better than RF.S glass but if you have EFS glass there’s is a fortune to be saved Using this adapter. You can buy the same with a filter drop in option but that’s nearly£350.

Perfect item works seamlessly

Good value, I can use all my L series EF lenses on the R5.

Works well with Other EF lenes as well.

Does the job perfectly

I just bought a brand new eos r50 upgraded from a rebel t7. While I was excited, you can’t help but think about all the money you invested in the other camera. It wasn’t too long ago that I bought a very nice 75mm to 300 Ef lens. Well this fixes just that problem you’re able to use all your older lenses and buy ef ones at a cheaper price in general. You can get a converter for cheaper but I recommend just splurging and getting this one it was made by canon so ofc it’s gonna work the best. The auto focus works better than it did on my actual mirrored camera, it fits perfect, and I got it used like new and it came in perfect condition. Highly recommend to someone who just upgraded from a mirrored camera!!!

Det är ju Canon original och den fungerar precis som den ska.

Korzystam w Canonie RP do obiektywów Canon 50mm i 75-300mm i działa idealnie.
