In my case I was looking to connect a Nikon fit Sigma Fisheye to a Sony A6300.The adapter successfully mated this lens & camera except that it is a "dumb" adapter in that there is no electrical control of lens features from the camera. So in my case, the lens had a manual focus ring, but Aperture was electrical so I was unable to change the F-stop from whatever setting the lens was at.So, if you are using this connector, ensure that any lens you wish to use has manual rings for all functions you need to be able to change.

I used this to adapt an older Nikon lens to my Sony A7iii cameraFit and finish of the unit is good and it does all that it was expected to do - there is no connection between the lens and the camera as it is full manual focus and f stop adjustmentif you accept this, then this adapter works just fineI can now use my larger old telephoto lens manually on my Sony camera

Overall - did the job pretty well for what it is. Negatives - the apeture clicks have very long step in between the f stops (4 clicks in total). I would prefer it declicked and smooth, with an f stop mark on the body). It is possible to declick it following some tutorials online, though.

Great quality adapter. Now I can use both my ais Nikkors and also my G series Nikons.

I knew this didn't autofocus - although it does meter correctly - when I bought it so that's not an issue. It's turned out to be an extremely cheap and cheerful way to try out my Nikon lens collection on an e-mount camera. Works a treat!

As with all K&F Concept Lens Mount Adaptors they are well made, provide a good fit and work as described. I have nearly a full set of the various mounts they produce and I have never had any issues with them at all. They have given new life to my vintage lenses, which in turn has given new life to my photography.
