NF-GFX (FR-NFTG1) Camera Lens Mount Adapter Auto Focus Built-in Electronic Aperture Compatible with Nikon D,G,E Lens Sigma Tamron NF to Fuji Fujifilm GFX100s/50R/50S Cameras Adapters…

This mount has been amazing. I've been able to use most of my Nikon glass with my new GFX100S-II. I only say most because two of my lenses were for aps-c. They still work but there is some hard vignette even with the 35mm mode on in the camera, nothing the mount can do with that though, just how it is with the aps-c type lenses. I've even been able to use an ancient full manual 28mm Nikkor lens to get some decent wide angle images while I save up for a Fuji lens. It is kinda nice carrying this big body around and a tiny lightweight lens around though. It is just a little tight on the connection to the body, but it has gotten better as its gotten a bit more comfortable with going on the body a couple times as i switch between my nikon lenses and the fuji 80mm. a couple of the nikon lens ive been able to use are a sigma 150-600, nikon 50mm. i have an older nikon dx af-s 55-200mm that has some issues focusing at times but kind of works. overall this is a great mount and all functions work on the lenses i'd expect them to.

I have a Nikon 500mm f5.6 and it works great with this adapter. and the 100s. The adapter fits a bit tight, but works. Amazing.

I was so excited to try this out and be able to use with my Nikon lenses, primarily the 58mm 1.4, 85mm 1.4 and 50mm 1.8. All three focused with the adapter but were too slow to be usable on my 50s II. It did focus accurately if my subject wasn’t moving too much and eye AF worked well. But since I primarily would be using this for portrait work it is not nearly functional enough. The information from the manufacturer does say if focuses better with the 100s so I am curious how much better it would do with that camera. But I have two AF lenses for the GFX system, the 63mm 2.8 which focuses decently quick for a medium format system, and the 80mm 1.7 which is known to be one of the slower focusing lenses for the GFX, and the lenses I tested with the Fuji to GFX adapter are way slower than the 80mm. If I was going to be using the adapter for landscape work then it would be fine since subjects are not moving, but this is unusable for people.

I bought this brand new and when i got it, it would only register every lens at f5 couldnt change it and even after putting the newest firmware in it still wouldnt work. It did autofocus but everything thing else was not working. I used the afs 85 1.4, 105 macro 2.8, 14-24 f4 and the tamron 35 1.4. All with the same issue the weird thing was the adapter would read f5 on all but every single one would be wide open so it wasnt actually closing down the aperture on any of them.
