I like this bag, perfect for all my camera and lens stuff

These are such a good idea and a nice piece of kit, especially if you have more than one camera, as you only have to pay out for one set of lens filters with these stepping adapters. One set goes up from 37mm to a big 82mm and the other set goes down from 82mm down to 37mm.They were easy enough to twist apart and twist back on. Took me a while to find the correct one to fit one of my camera's for a particular lens I wanted to try out, but didn't have to take one off at a time so that was good.The threads are nice and neat and not cross threaded, so they are easy to twist on and off. I like how they are labelled clearly so when I was using a 52mm lens filter on a 72mm lens thread I had to untwist the 72mm lens adapter all the way down to 52mm ( I think it was 7 adapters attached) and then screwed the lens filter on to the last one.Seem really well made of light aluminium, clearly and nicely marked and so easy to use.I was sent a sample to test out and give an honest review.

The K&F adapters that I own (MD and M42 to FX) were previously the "normal" version. The pro version is indeed accurate as the name suggests. Flawlessly processed, precise and soft locks AND looks great on the camera or in connection with the lens. Since the diameter is continuous towards the camera bayonet, the adapter forms a line with the lens. Clear recommendation!

have a few of these K&F adapters for mounting various vintage lenses on my cameras - I use Canon and Fuji ASP-C and M4/3 cameras and they are brilliant on all 3. Great price, well made and they work really well.

I have an old Canon 550D and some Lens. And now I've bought a Canon eos m100. I want to keep using my EF Lens. Then I buy adapters. This works perfectly and can autofocus very quickly.

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 finished. When I check them with a caliber, the two sides of the adapters appear planar (but I don't have any wide-aperture lenses to test that on). On the camera side, they are all precise and without light leakage. On the optical side, I noticed a slight light infiltration on two adapters. Of course, I purposely searched for them by bringing a 500 lux LED flashlight half a centimeter away from the adapter. Light penetration is very unlikely in normal situations (perhaps on an easel on the beach in August). I solved it anyway with a small rubber grommet. If you're shooting freehand, that's not necessary, the hand is hiding a possible infiltration. Overall they look like good adapters to me. Due to their robustness, they can withstand lenses up to 600/700 grams. However, I would not mount lenses that are larger than one kg on the nose.

This adapter opens the lens of my Leica camera with a Canon lens

treated myself to this adapter to adapt old lenses with the Canon FD bayonet to my mirrorless Canon RP. This works absolutely perfectly. The adapter sits on the EOS-R bayonet without any play and the FD lenses fit snugly on the adapter. Focusing to infinity is possible. That doesn't seem to be the case with all adapters. With the corresponding K&F adapters, I have already had good experiences with my Olympus OMD EM 1.2. It is important that the locking ring on the adapter is first turned in the "OPEN" direction. Then the FD lens with the smallest f-number, eg 1.8 or 1.4, is attached, 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 variant; there he can easily adjust himself in the direction of "OPEN". That's where you learned. Therefore, this adapter receives my unreserved recommendation. I will gradually buy more K&F adapters (e.g. M42) for the RP, simply because I have not been disappointed by the price/performance ratio so far.
