Seems well made, especially for the price. Accepts Nikon Ai/D/G lenses At first I couldn't attach the adapter to the Nikon lens. From a web search it seems it takes more force than you might think to put the Nikon lens on and snap it into the adapter. The subsequent assembly of the lenses went more smoothly. I was expecting to be able to use the aperture rings on the D and Ai lenses to control aperture, but that doesn't seem to have any effect. The outer ring used for the G lenses' aperture setting works with them, allowing me to control the aperture (though not as precisely as the D/Ai lenses' own aperture rings). Seems "good enough".

This is an excellent product, not sure why some people say these aren't good. The fit and finish are impeccable. The lens fits snugly and securely to the adapter, yet is just as easy to attach and detach as the original lens on the camera. The adapter itself fits just as securely as the original OEM lens on the camera body. This lens adapter literally saved me hundreds if not thousands from being able to use all my other different lenses including long telephoto lenses. If you already have a collection of different lenses for different frames I can't speak for other brands that I haven't used but these K&F adapters do (LOVE THEM)

have requested the item which has arrived to me in a very short time. As expected it can only be used in manual form but I find it extremely useful and of high quality because I can use the old Nikkor lenses (including a Sigma 24mm) and use them with my Fuji x t20. The adapter doubles the focal length of the lenses and it suits me well. Great buy I would say.

I didn't trust lens adapters at all as I had one and it broke a lens. On the other hand this one works quite well, I've tried it with several lenses, a 50mm AF-D 1.4 and an 85mm AF-S 1.8 and it runs very well, I don't give it 5 stars because the aperture ring has few stops, so same thing , you're in a 1.4 and you want to close a bit and the next level is 2.8 or something... I miss those intermediate steps that are necessary in many situations. Despite this, it works very well, is robust and the lenses fit very well. I don't recommend it because of the few level changes in the diaphragm, but the truth is that it's the first adapter ring that gives me confidence. If you can't find another that solves the membrane problem, this product is a good buy.

This allows my Nikkor lenses to adapt to use on my Fuji X-E2. The size is the same as my other Fotodiox Pro. Also has the manual adjustment of the aperture ring to 6 clicks like the Fotodoix. But much cheaper. Quality is made from aluminum. I also love the silver aperture ring that goes with my Nikkor lens on my X-E2 - see guide photo with my 40 year old 1.2-55mm lens. The price is good. Also works on my G lens and non-G lenses (where the aperture is on the lens). Remember that this is all manual control. Fits best with 1.8G, 35mm and 50mm and 1.2-55mm fixed focal length Nikkor lenses. Not suitable for zooming as it is more difficult to focus manually and the camera body shakes if you are not using a tripod. You'll get frustrated if you don't shoot infinity, then spin it all the way and you're good to go.

This adapter adapts my Nikkor lenses to my Fuji body (X-T1). It works perfectly and looks very good too. Like the flat black and silver rim. The silver ring in the center is for aperture control, so it also works for Nikon G lenses without an aperture ring and allows you to manually control the aperture of your Fuji. My copy is a little tight on the Nikon receiving end but works very well. And since I've had a few that were too loose, I don't mind. The aperture ring is 6-7 clicks so is better than the Fotiodix version I have which is only 3-4. Not much more to say but that it works well and allows me to use all my Nikon lenses on a Fuji body. Of course, this is all manual control, not autofocus or exposure control — just a metal tube that lets you mount Nikon lenses. At this price it's a great deal and works beautifully. It wasn't available for Prime when I got it and it took me about 2 weeks to get it.

Simple but well made article. It pairs a Fuji XT1 with some Nikon AI, D and G series lenses without hesitation. No mounting problem, it also withstands fairly bulky lenses well. It's not the first product I've bought from this brand, so far no problem

had bought a Fuji X-T10 mirrorless camera and was waiting for a Fuji lens to arrive so I could use it. I had a Nikon 35mm g at home and I was thinking about using it on my Fuji while waiting for the proprietary lens. After careful research I have ordered this wonderful adapter which I will try to describe below. It arrived in a small cardboard box wrapped in shockproof plastic. The adapter is made of excellent material, it is made entirely of metal and is pleasing to the eye. It can be installed easily and quickly on both sides. It has a metal ring that is used to close and open the membrane. That last feature deserves an explanation: the adapter has no electrical contacts, so any lens you mount will lose autofocus. If you mount a lens that is equipped with an aperture ring, you can use it without any problems because the adapter does not interfere with this ring. On the other hand, if you mount a lens without an aperture ring, as in my case, you can have trouble selecting the apertures that the mirrorless camera actually no longer shows on the display. However, this adapter features a ring for minimal control of the diaphragms. To get the best out of it, before mounting the lens, make sure the adapter ring is fully closed (smaller ball), then mount the lens. Then mount the adapter on the camera. In the case of the XT-10, I had to select non-lens speech noise from the settings menu and that was it. Despite the lack of autofocus and minimal control over the apertures, I took wonderful photos. Highly recommended for those who are already experts at manual focusing.

My first attempt at fitting a lens, it works great with my Nikon FX and D series lenses when used on the X-T4. The aperture ring could be a bit more precise to move the apertures, other than that it's a great kit!

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.
