bought three adapters with a Canon R mount (one for Leica R, one for Contax and one for Minolta MD). They all reach exactly infinity. The internal anti-reflective paint is well made. When I check them with a caliber, the two sides of the adapters appear flush (but I don't have any large aperture lenses to test this on). On the camera side, they are all accurate and light-free. On the optical side I noticed a slight light infiltration on two adapters. Of course, I deliberately looked for it by bringing a 500 lux LED flashlight half a centimeter away from the adapter. In normal situations it is very unlikely that light will penetrate (perhaps on a donkey on the beach in August). I solved it anyway with a small rubber seal. If you shoot freehand, this is not necessary, the hand covers possible infiltration. Overall they seem like good adapters to me. Due to their robustness, they can withstand lenses up to 600/700 grams. However, I would not mount lenses larger than one kg on the nose.

With this adapter I can finally use my old FD lenses on my Canon RP camera! This works surprisingly well. Of course you have to focus manually again, there is no more Exif data except shutter speed and ISO values, but who cares. Mirrorless cameras often have so-called focus peaking (the focus area is highlighted in color), this is a good and fast way to get the subject in focus in the right place. I have something to complain about too! The locking ring, which holds the lens in place and at the same time ensures that the aperture can be adjusted, always rotates in the aperture direction. That sucks because if you don't check it constantly, the aperture will pop open! Lockable with a button would be better

The adapter is very well made. Fits perfectly on the Canon R. A Minolta MC Rokkor 1:1.7 55mm can be operated on it without any problems

I have a few from K and F... Everything was always great. Like now. Functions perfectly.

The build quality, materials, attention to detail and overall look and feel are stunning. All-metal construction. The supports are well machined and show no play whatsoever. The metal lock knob has just the right amount of resistance. The Canon flange is fitted with circlips to reduce any play in the connection, the inside of the cylinder is painted matt black to reduce any internal reflections. Overall a great product at a great price.

Great, solid adapter that sits firmly on the Canon without any play. I also think it looks very nice, I hesitated given the price, there are much cheaper alternatives, but the quality is convincing everywhere. I also love the high-quality mats on the inside of the adapter to reduce or perhaps even prevent extra stray light. If I look for an adapter for my objects again, it will definitely be one from K&F Concept. You get great quality.

got this adapter to adapt old Canon FD bayonet lenses to my Canon RP mirrorless. It works absolutely perfectly. The adapter sits on the EOS-R bayonet without any play and the FD lenses fit the adapter well. Concentrating to infinity is possible. This does not seem to be the case with all adapters, I have already had good experiences with the corresponding K&F adapters on my Olympus OMD EM 1.2. It is important that the adapter lock ring is first turned in the “OPEN” direction. Next, the FD lens with the smallest aperture number, for example 1.8 or 1.4, is attached, and then the lock is turned to “LOCK”. The desired aperture can then be selected manually on the lens. The locking ring on the FD-EOS R adapter is much tighter than on the MFT version; There it can easily be set in the “OPEN” direction. You learned something new there. That's why this adapter receives my unreserved recommendation. I will gradually buy more K&F adapters (e.g. M42) for the RP as I have not yet been disappointed with the price/performance ratio.
