Betrayed by the age and weight of the bodies and lenses, I bought a lighter and more modern Sony body. The Canon 28-105 USM was a faithful companion, so I can keep it thanks to this adaptor ring.

Does it exactly what it needs to do, allowing me to use my old Canon lenses on my new mirrorless camera. The supplier was amazing, quickly and efficiently responding to my need for a replacement part which arrived in good time and without charge. I couldn’t be happier.

Nicely designed and nicely packaged- unobtrusive piece of kit, which is all you can ask of an adapter…

EDIT: After contacting customer service thru email and explaining the situation, they mailed over another copy of their product and the new adapter worked. Autofocus worked and I was able to adjust aperture smoothly like any other lens with the Canon EF 70-200mm f/2.8 III
The only difference that I noticed between my copy from Amazon and the copy sent over directly from K&F was that the Amazon copy didn’t come with the small hex key adjuster. This leads me to assume that my Amazon copy might’ve been a returned and defective product.
If you’re like me and the product doesn’t work and you can’t get Amazon to exchange it, go thru directly to K&F. They’ll work with you and that’s a plus in my book!
Original: This adapter does not work with Canon EF 70-200mm f/2.8 III and Canon EOS RP. When connected, camera settings show MF only, no AF or aperture control.
The adapter works well with a Sigma 28mm f/1.4 ART lens, so this may be an issue with Canon lens compatibility (which would severely limit the adapter's usefulness).
I WOULD NOT RECOMMEND THIS ADAPTER

At half the price it does the same job connecting my range of lenses to my new camera. Fantastic quality, seamless adaptor between ef and rf mount
