Nikon F lenses on Fuji X
Yes, this works. Nikon F has a 46.5mm flange distance and Fujifilm X-mount has 17.7mm, so a 28.8mm mechanical adapter with no glass fills the gap and infinity focus is preserved. Focus and aperture stay manual.

Setting it up
Set Shoot Without Lens to On and enter the focal length under Mount Adaptor Setting so stabilised bodies and EXIF know the lens. Focus peaking and digital split image work with any adapted lens.
Automatic diaphragm. Off the body the lens sits at the set aperture, so the aperture ring works directly on an adapter.
Nikon F lenses and their field of view on Fuji X
Effective focal length changes with sensor size. The lens itself does not change; the smaller sensor simply captures a narrower part of the image circle.
| Lens | Focal length | Aperture | Frames like (APS-C (1.5x)) | Years | Used value |
|---|---|---|---|---|---|
| Nikon Nikkor 105mm f/2.5 AI-S | 105mm | f/2.5 | 158mm | 1981-2005 | $150 to $450 |
| Nikon Nikkor 35mm f/1.4 AI-S | 35mm | f/1.4 | 53mm | 1976-2020s | $350 to $900 |
| Nikon Nikkor 50mm f/1.2 AI-S | 50mm | f/1.2 | 75mm | 1981-2020s | $400 to $950 |
| Nikon Nikkor-S Auto 50mm f/1.4 (pre-AI) | 50mm | f/1.4 | 75mm | 1962-1974 | $60 to $220 |
Frequently asked
Do Nikon F lenses work on Fuji X cameras?
Yes. A plain Nikon F to Fuji X adapter works with no optics. Nikon F has a 46.5mm register and Fujifilm X-mount has a 17.7mm register, so the adapter is a 28.8mm tube that puts the lens exactly where a Nikon F body would. Plain adapter ring for every manual-aperture Nikkor. Pre-AI lenses mount freely on adapters; their only compatibility problem is with later Nikon bodies whose meter-coupling tab they can bend.
Do Nikon F lenses focus to infinity on Fuji X?
Yes. Because the adapter restores the native 46.5mm register, infinity focus is preserved and the full focus scale on the lens stays accurate. Adapters machined slightly short let the lens focus past infinity by a small margin, which is harmless; adapters machined long stop short of infinity, so buy from a maker with tight tolerances.
What focal length does a Nikon F lens become on Fuji X?
On APS-C (1.5x) Fuji X bodies (X-T, X-H, X-Pro, X-E, X-S, and X-M series) a 105mm lens frames like a 158mm lens on full frame; the aperture and depth of field at a given distance do not change.
