FotodioX Pro Nik(G)-GFX Adapter for Nikon F Lens to FUJIFILM G-Mount Review

The FotodioX Pro Nik(G)-GFX is a mechanical mount adapter that lets you use Nikon F-mount lenses on Fujifilm GFX medium format cameras. Priced at $78, it fills a niche for photographers who already own Nikon glass and want to experiment with it on the larger GFX sensor without investing in native Fujifilm glass. The Pro designation suggests solid build quality typical of FotodioX's higher-tier adapters, and the G designation indicates compatibility with Nikon's aperture-ring-less G-type lenses via a built-in aperture control ring.

Keep in mind that Nikon F-mount lenses project an image circle designed for full-frame sensors, which is smaller than the GFX's medium format sensor. This means significant vignetting or image circle cutoff is likely in most cases, limiting practical use to cropped shooting modes or creative effects. Manual focus and manual exposure are the norm with this type of adapter, so it's best suited for deliberate, slower shooting rather than fast-paced work. This adapter makes sense for users who understand its optical limitations and want to repurpose existing Nikon lenses for specific projects or tighter framings on the GFX system.
