The device worked flawlessly with my Nikon F lenses and Fuji XT-4. For AF-D lenses, you can set the adapter's aperture to its smallest size and then control the aperture ring on your lens to achieve a more accurate aperture). With G lenses, the aperture is controlled by the ring on the adapter. I've tried zooming in from wide-angle (14mm) to ultra-zoom (400mm) and it worked with no problems. I could have paid 5x to 10x for the adapter so that's a real saving here.

It works as expected and according to previous comments on Fuji X. It's very easy with the focus assists and final photo view. Suitable for relaxed and leisurely photography. With G lenses you operate the aperture control on the adapter and with D and Ai you have to place it on the right (seen from behind) and operate apertures from the lens, with the advantage that in the second case you know which aperture you are working on. Recommended.

Great little adapter. The fact that it only has 6 detents in the aperture ring is irrelevant to me: if you're using a lens with its own labeled aperture ring (like my Nikkormat 50mm 1.4), you'll maintain precise aperture control by simply turning the adapter to " fully closed” and then dial it in normally on the lens! Build quality is good: it's mostly metal and feels like a solid device (although you pay for that with the weight: it's quite heavy). It's easy to use and my specimen fits securely on both the camera body end (on my Fuji X-T20) and the lens end, giving it a snug fit with no wobble or play. Focusing on infinity seems correct. One minor complaint: it would be nice if it came with a rear cap when not in use.

Tested on an X-T1. This ring is compatible with Nikkor G-type lenses — a lens that doesn't have an aperture ring, like the 105 AFS 2.8 Macro, thanks to the silver ring that controls the 6-notch lens aperture. Of course you lose the autofocus of the lenses, but not the automatic exposure, when you are in mode A. Good firmness of the mount, nothing moves. It is also compatible with the older AF-D series lenses (85, 105). In this case, the lens aperture ring is operational. Precision: With AF-D lenses, the aperture ring on the K&F ring is operational, with function dependent on lens aperture ring position.

Merchant sent me the wrong adapter. I only realized this when I took it with me on a trip home to try it out with my old Nikkor lenses. Amazon promptly replaced it with the correct item after I got back. Now I'm super happy with it and plan to buy more manual Nikkors on eBay. This thing just works. Just remember to keep the aperture settings on the adapter as small as possible if you have aperture controls on the lens. If you have it wide open, it stays wide open no matter how you adjust the controls on the lens.

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.
