This adapter is an awesome addition to my gear. I have a lot of great Nikon glass and I recently invested in a Fuji mirrorless system. This adapter allows me to use my favorite Nikon lenses on my mirrrorless system. I do wish the aperture ring had more stops than 4.

This is an excellent product, not sure why some people are saying that these are no good. The fit and finish is flawless. The lens fits tight and secure to the adapter while still being just as easy to install and remove as the original lens is to the camera. The adapter itself also fits secure to the camera body just the same as the original oem lens does. This lens adapter has literally just saved me hundreds if not thousands by being able to use all my other various lens, including long tele lens. If you already have a collection of various lens for various mounts, I can't speak for other brands that I have not used but as for these K&F adapters ( I LOVE THEM )

I bought this adaptor to use my old Nikon (Nikkor) glass with a Fujifilm X-T1 I purchased expressly for that purpose. The adaptor works perfectly for this purpose. Connection is positive and firm. You may have to wiggle the lens just a bit to get a positive lock but this is true with Nikon bodies as well! I have used the adaptor with F mount and E series lenses and it performs all functions as advertised with the X mount Fuji body. Yes, the camera must be set in manual mode by the switch on the front of the body and in the menu "use without lens" must be set to "yes". It is also possible to use the camera in aperture priority mode with a manual lens. (you pick the f stop and the camera selects a shutter speed.

It is so much fun to get the old glass out and shoot manually as in my old film days. While my old Nikon lens with work manually on my Nikon DSLR, the fiddle factor is too great to make it worth while. With a Fuji X-T1 or similar body all the manual controls are right there making using the old wonderful lenses that you paid high dollars for easy to use once again. This adaptor seems comparable to many I've looked at selling at a much higher price.

I bought this adapter at the recommendation of other Fuji users. My initial impressions are that it is well made, and my Nikon F-mount mount lenses fit it just fine. There is a very little rotational play both between the adapter and the body and between the adapter and the lens, but nothing that concerns me. There weren’t any metal shavings and both mounting surfaces felt smooth. I don't need the aperture control ring as I do not own any G-type lenses but it moves smoothly but overly freely. The adapter feels better than my Fotodiox FD to MFT adapter for those who own a Fotodiox adapter and want to compare. I appreciate it comes with a plastic case, though padding could be open-cell foam and not bubble-wrap.

There is no lack of excellent reviews for Fuji X lenses, but excellence has a price. Fuji glass, particular the primes, is pretty far from affordable for most enthusiasts. For Nikon shooters wishing to take advantage of the iconic performance and great out-of-camera JPGs of Fuji X bodies but don't want to spend a fortune on Fuji's primes, this adapter is a real option to be able to squeeze more life out of 'old faithful,' that lineup of stellar Nikon F and G glass that many Nikon shooters have in their inventory.

The lens to adapter side seemed a little tight the first couple of mountings, but has become very smooth with a little use. Lenses mount without play. The built-in aperture ring does a decent job of opening and closing the aperture in G lenses. As many have pointed out, the travel distance for aperture modulation of Nikon glass is very limited, so one may end up closing the lens down more than intended. Of course, there's also no way to know the precise aperture when using Nikon G lenses with this adapter.

Once users become used to manual focus with their Nikon glass when using this (and other) adapter(s), and this should not be difficult with the focus peaking of most Fuji X APS-C bodies, they may conclude that the combination of Nikon lenses and Fuji X bodies is something special.

Who knew that the drawer full of Nikon lenses would get repeated new leases on life on Olympus, Sony, and now Fuji bodies with adapters.

Fantastic adapter for the price. Machined very well and of apparently solid quality. Gives you the option of either direct lens aperture control (older and D series Nikon glass) as well as around 6 "clicks" of control of G-series lenses from wide open to closed. The aperture ring on this adapter is smooth to turn and stops are tangible (clicked into) albeit it has a very short throw. It would be ideal for it to be geared to extend the travel on this ring by 2x and also provide finer control of mid-stops. At this price, it actually gives you an option of purchasing an adapter for each lens that you own and use with a Fuji body. Just awesome.

Finally can use my Micro Nikkor for something other than as a paperweight

Appears well built considering low price. Very tight fit (compared to Nikon original adapters) but hopefully will become looser and smoother over time. Using on Fuji X-T30. Bought to use with Micro Nikkor 60mm for close ups. Will likely use on tripod much of time.

Honestly, I probably won’t use often, but it was certainly worth the low price.

Adaptor for Nikon DX lens on Fuji XT-3 body.
Quality machining; mates easily on the body, latches positively and with no discernable movement. Same for accepting the Nikon lens. Cosmetically, could be a tad better finish, but this is no issue - surface only.
Overall, works as advertised, no issue here. Suddenly I have a full line of DX prime lenses that otherwise had been sitting unused since moving to the Fuji X camera. The same might be true for you.
As an aside, and this is only for the manufacturer, because for the price really one cannot ask for anything more: it would be great to have a plastic cap at the camera end of the adaptor: that way, if predominantly using one lens, the user would not have to dismantle two components everytime when switching lenses. Anyway, this does not take away from the functionality as advertised.
Note: when operating, remember to select "Shoot Without Lens" in the Fuji setup menu.

It does what it says it does; it will allow your Dx lenses to work on the Fuji X system, for me, the X-T30. Of course the lens becomes manual only and the is limited data; you gave to guess the aperture by the "clicks" when you turn the ring. I found it worked much better with my fast prime lens (picture is from a 50 mm F1.8) my 18-200 F3.5-5.6 did not work nearly as well, especially the aperture control. Overall, I would recommend, as long as you understand what you are getting.

This adapter works great on my XT1 and all my Nikkor lenses. The only lens that doesn’t work is my 10-24 Tamron Di ll because that lense has no mechanical aperture control. Quality is as good as it gets.
