K&F Concept EF to EOS R Adapter, Auto Focus Lens Mount Adapter for Canon EF EF-S Lens and Canon EOS R/RF Mount Cameras
SKU: KF06.520
This adapter is solid and holds the lens on very well, but I have one weird issue (and I am giving 5 stars because I am not sure if it’s the adapter or the camera). When putting a different lens on, I leave the adapter on, turn off the camera and swap the lens. I then have to pull the battery and put it back in, or the camera won’t power (canon R7). You can hot swap by changing lenses with it on and there’s no issues (though I did have an autofocus issue for a little bit and it fixed itself). Again, no idea if it’s the adapter or the camera. Besides that, solid and keeps IS, aperture, and focus abilities available.

I have 4 EF lenses and only 1 original Canon EF/RF adapter and two bodies so wanted another option.
Given the 50% price increase Canon did i looked elsewhere. This unit gets good reviews and so far after testing on an apsc and full frame body it works pretty much as well as the Canon.
No AF issues or exposure and tried it with a f1.4 and f2.0 L lenses as well as a cheap kit lens.
Yes, it is a little tight getting the lenses on and off the adapter but not a big deal.
Tried it on soccer and worked the same as the Canon so if it can shoot sports it is a great adapter.

this unit does not provide AF for the EF 85mm 1.2 lens and has to operate in manual focus. However, when switched to the EF 35mm f1.4 the AF is working.
I'm not sure why and decided to return this unit and get another brand.

K&F has created a very high quality lens, the materials are very good and resistant. I have tested it by mounting a Sigma 18-35 on a Canon EOS R series and it works wonderfully.

Out of this box this feels solid. Connects to my camera body without issue and works pretty well from what I can tell. I only have one older lens so I havent done extensive testing on this but what I have works like a charm so this is great. Cant wait to expand my lens collection and put this through its paces. Very happy with this.

Great purchase with an excellent quality/price ratio.
The ring is well made, made entirely of metal
it fits perfectly into the camera
just as the K lenses attach without any problem!
The only shame is that it does not have caps (a minor problem)
HIGHLY RECOMMENDED!!!

It fits perfectly from the Canon lens to the Sony A6000 camera, although only manually. If the Canon does not have a diaphragm in the ring that you can turn by hand, it does not work.

The price-performance ratio is right!
The goods arrived on time, as usual from K&F Concept. As far as I can tell as an ambitious hobby photographer, the product does what it promises. In any case, it meets my personal expectations. Its durability remains to be seen. However, based on my previous experience with other products from the company, I assume that this autofocus adapter will also serve for a long time. The feel and appearance are of high quality in my opinion.
