M42 42mm Screw to Fuji Fujifilm FX XPro1 X-Pro1 Lens Mount Adapter Ring K&F Concept Lens Adapter
SKU: KF06.058
Fantastic adapter for the price. Very well machined and seemingly solid quality. Gives you the ability to either directly control the aperture (legacy lenses and Nikon D-series lenses) as well as about 6 "clicks" to control G-series lenses from lens wide open to lens closed. The aperture ring on this adapter rotates smoothly and the f-stops are tactile (clicked in) despite being a very short distance apart. It would be ideal if it were oriented to add 2x the travel on this ring and also allow for better control of the mid stops. But as far as editing and price go, know that you're probably getting the best value for your money here. At this price you actually have the option to buy an adapter for any lens you own and use it with a Fuji body. Just awesome.

It works well, difficult to fit on the lens but NOT on the camera. You have to use force to block it on the lens. A little scary when you do it for the first time! A bit heavy because it is made of metal, but very robust. Works exactly as described. Manual focus is easy, but you have to guess your aperture value.

am impressed with the quality of workmanship on this very affordable adapter, which is what you would expect from a high end product. My Nikon lenses fit the adapter like a Nikon camera body and connect perfectly to my Fujifilm camera bodies. This is a dumb adapter, meaning there are no electrical connections to the camera, so focusing has to be done manually and auto exposure is only available on aperture priority auto exposure. Given its limitations, I highly recommend this K&F adapter.

Exactly what I needed. It fits super perfectly in my Fuji mirrorless camera, it clicks right when installed (so good!) and the connection is solid, no wobble. I tried connect/disconnect the 4 Nikkor lenses with no problems. The aperture control ring has 6 clicks from wide to narrow, which is good enough for general purposes and it has good resistance so the aperture doesn't change accidentally. And that adapter looks great too! What's not to love? Update: I've tried this adapter with the Nikkor 85mm F1.8d and it doesn't lock the lens in place...not sure why. I have other "D" lenses and they work fine.

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.
