[Metal, Brass] I have 6 Nikon lenses and wanted to use them on my new love, my GFX 100s. Love this camera but only have 2 lenses for it the 45 and 110. Now I have 8 lenses for it and it's all thanks to this inexpensive adapter. These are some things you need to know. On the GFX 100s , go to SET UP in the menu. Under SET UP go to BUTTON/DIAL SETTING. Shoot without lens is under this section, turn it on. If you want the camera to use only a 35mm equivalent part of the sensor go to SHOOTING SETTING to find 35mm format mode but if you want to choose yourself what format you would like to shoot in, leave that off. What I have found is, some of my lenses cover the entire sensor better than others, but surprisingly there isn't as much vignetting as I expected. Cropping the full GFX sensor slightly to the standard 8x10 format seems to eliminate most of the darker corners. I have not found it difficult to focus using this fantastic camera and the Nikon lenses manually but shooting up close and wide open yields some too soft results. My 20mm 1.8G Nikon did great up close though and this camera delivers so much information cropping is no problem. I've had no problem getting any lens on the adapter or the adapter on the body. I've only put the adapter on the body with a lens already on the adapter, but once on , I have changed lenses without removing both. BTW, the adapter comes with no instructions at all. I do set the red adapter ring to the widest opening when attaching a lens and the Nikon aperture ring lock is set to off. Once on the camera, I move the red ring to the smallest opening and on Nikon lenses with an aperture ring, I can then control the aperture from the lens, not the adapter. Simpler to use than I expected and has opened up a whole new way of looking at how to use this camera.

[FUJIFILM X] Works great at adapting my legacy lenses to the GFX.

[0.5 lb] This Fotodiox adaptor fits Perfectly. Its so well made. Highly Recommend

[FUJIFILM X] I knew that the tilt-shift lens would be a challenge but I found a website called Northlite Images with an enormous amount of information. After several trials, I learned the technique. Which I have to say was well worth the effort. I do product photography for my partner's ETSY website and encounter a myriad of items to photograph I find that the tilt-shift had improved my composition shots right off the bat.

[0.5 lb] Having used this product for roughly a week, I am still amazed every time I use it. To have an adaptor from two different worlds to take my artistic whims to a different level is inspiring. My girlfriend has upgraded to a Nikon Z7, and having kept her 100 mm macro lens from her previous set-up was all but happy to lend me her lens ... for a while. The FotodioX is really, really well made, I can only but recommend it. Cheers, R

[0.5 lb] I own a few manual focus Nikon AIS and non AIS lenses. This adapter works as advertised, has smooth operation, I can use it as a normal straight through adapter, and best of all I can access tilt shift functionality on my Fujifilm cameras. I find it to be a well made adapter, worth the cost, and using the tilt-shift on the Fuji enables new and interesting compositions. I highly recommend it.

[0.5 lb] The one I got works perfectly, and aperture rotates smoothly. Does exactly what it's supposed to do, and can't beat the price!

[0.5 lb] Well made. Allows me to use all my Nikon lenses on my Fujifilm GFX 50s, although in manual mode only.
