I treated myself to a Leica Summicron R 50mm f2 for my Nikon D750 and now needed an adapter. This one is attached instead of the Leica bayonet with the 6 existing screws. (Please make sure that the small ball that does the rastering of the two doesn't get lost. All you have to do is put the bayonet up and slowly lift off the old bayonet ring!) The lens fits like one, and focuses cleanly to infinity . The camera does not recognize any lens data and there is no jumping aperture either, but the exposure is still great. The adapter is therefore really recommended.

Mounting Nikon lenses on the XT2 and this adapter works very well. No sacrificing quality as there is no glass, it is just a mock adapter. I've tried various Nikon G lenses and Zeiss ZF mount lenses and had no problems. The mount or lens doesn't play and it feels secure. As with most other adapters, there are no aperture markings at all, leaving you guessing with any lens that doesn't have manual aperture controls. At this price you really can't go wrong!

By converting the M42 mount to a Leica M mount and using Techart's AF adapter, you can shoot autofocus with the Sony α7III. I can cover up the fact that it became difficult to concentrate because of Toshi. So I bought the M42 lens again because I left it on with the intention of remodeling it straight away. If you remove it, you won't understand.

Perfect service

The adapter is very well made and makes a high-quality impression. The fit is perfect both on the Leica bayonet and on the M42 thread side. Nothing wobbles or sticks.

Got the L/RL/M adapter to use a Leica R Macro lens on the Leica M for the few macro photos I take. I didn't feel like paying 160 EUR for an original Leica adapter, so I bought this one from K&F. R lens fits perfectly with no play, and the connection to the M camera is also perfect. It goes up and down nicely, without exerting any force, without anything wobbling. Perfect for my area of application. I've bought 3 K&F adapters so far and I'm super happy with them. They make a valuable, stable impression. It may be that after years they no longer have the quality of a Leica original due to larger manufacturing tolerances, but currently. it's great

With this adapter I can use all my Nikkor or Nikon lenses on the Fujifilm E-X1. However, it is necessary to set the “Shoot without a lens” option in the menu, otherwise the shutter button will not click. The diaphragm is closed by the intuitive ring. I tried it with a G Sigma EX 1 lens; 4-5.6 with 10-20mm focal points (equivalent to 15-30mm of a full frame): The ring allows you to close the aperture while maintaining full aperture for manual focus, from 24cm to infinity. Of course, the Fuji ring works better for Leitz M lenses, since it is enough to set "adapter" and focal length and any distortions can be corrected. But it costs more than ten times as much. Focus is obviously done manually as with digital and analogue Leica Ms. The courier was unable to deliver on the scheduled day, claiming that "no one was there". Instead we were all there. Saturday to Monday. Then don't complain if Amazon will use drones.
