What this adapter preserves
Compatibility for Nikon F lens on a Fujifilm X body (computed from the lensmount dataset — open the Nikon F to Fujifilm X adapter page for the full verdict, flange clearance, and adapter caveats).
- Focus: Manual focus only
- IS: Lens-only IS
- Aperture: Adapter aperture wheel
- Infinity focus: Reaches infinity
Format note: Lens covers full-frame; body is APS-C — 1.5× crop factor applies relative to the lens's native image circle. No vignetting; the body uses the centre of the lens.
What it does
Recycled-aluminum body, anodised matte-black finish, plastic-free packaging, tree-planting commitment per product.
Common questions
- Will the X-Trans body's autofocus work through this adapter?
- No — purely mechanical, no electronic communication. Manual focus only, using the X body's focus peaking and magnify-to-focus aids. For AF preservation on F-mount through to Fujifilm X, there's no widely-available third-party AF F-to-X adapter currently shipping.
- Is the 1.5× APS-C crop a problem for vintage AI Nikkors?
- Depends on the lens. Standard primes (50 mm f/1.4 AI, 35 mm f/2 AI, 85 mm f/1.8 AI) become tight portrait lengths on APS-C (~75, 53, 128 mm equivalent). Wides become harder — a 24 mm AI gives a 36 mm equivalent, perfectly usable but not wide. The crop is purely a framing effect; image quality on the central crop of a full-frame Nikkor is often excellent on the X-Trans 26 MP sensor.
- Does the adapter's built-in stop-down ring cover all G-type Nikkors?
- Yes — the stop-down ring engages the aperture lever on every G-type F-mount Nikkor (G primes, G zooms, including PC-E shift Nikkors when used at zero shift). E-type Nikkors (with electromagnetic aperture from 2007+) cannot be controlled by the mechanical stop-down — those lenses default to wide open through any mechanical adapter and require an electronic adapter (none widely available for X-mount currently).
