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.

This K&F Concept adapter is well made and fits my relatively heavy Zeiss zoom lens and my Fuji XT1 which provides the stabilization I was hoping for. worth the extra cost over cheaper adapters to gain that trust. Like other third-party adapters, this adapter requires manual focusing.

Very impressive! I was looking for a good Nikon to Fuji adapter after buying my own adapter from Lomographys which was way too tight on my Fuji x-e3. I also have the k&f concept m39 and m42 adapters which I love. This adapter makes my beautiful $500 achromatic lens a joy to use. It's sturdy, comfortable to use and doesn't wobble at all. Very pleased that I can now use this lens without fear of damaging my camera with a poorly made adapter. Lomography notes that their lenses are amazing, but k&f makes better adapters. I am now looking forward to collecting some vintage Nikon lenses.

ABSOLUTE BUY RECOMMENDATION!!!!!

There is no shortage of excellent reviews for Fuji X lenses, but excellence comes at a price. Fuji glass, especially the Primes, is far from affordable for most enthusiasts. For Nikon photographers who want to take advantage of the iconic performance and great JPGs of the Fuji X bodies without a camera, but don't want to spend a fortune on Fuji's primes, this adapter is a real option to get more life out of 'Old Faithful', the Set of outstanding Nikon F and G lenses that many Nikon shooters have in their inventory. The side between the lens and the adapter seemed a little tight for the first few mounts, but has become very smooth with a little use. Lenses can be mounted without play. The built-in aperture ring allows for proper opening and closing of the aperture on G lenses. As many have pointed out, the aperture modulation travel of Nikon glass is very limited, so you may end up driving the lens further down than intended. Of course, there is also no way to know the exact aperture when using Nikon G lenses with this adapter. Once users get used to manually focusing with their Nikon glass when using this (and other) adapters, and this shouldn't be difficult given the focus peaks of most Fuji X APS-C bodies, they might come to the conclusion come that the combination of Nikon lenses and Fuji X bodies is something special. Who would have thought that the drawer full of Nikon lenses on Olympus, Sony and now Fuji bodies would be revived over and over again with adapters.

already owned a K&F adapter (Minolta MD to Fuji X) and was already impressed by the quality. The adapters have no recognizable play on the bayonet, they are still processed cleanly, as far as I can judge as a layman. No sharp edges, no protruding parts. The adapter from Nikon G to Fuji X differs from other adapters by the aperture ring, which sits firmly and is pleasantly soft and valuable. The aperture can be regulated very well and there is still no play to be seen with this adapter, despite the obviously more complex design. Focusing works indefinitely. Absolute purchase recommendation!

Thank you very much.
