Adapter Nikon F-lenses to Fuji G-Mount. The precise design of the adapter allows for accurate compensation of the focus length difference between the two mounts. The connected lenses can focus manually up to infinity. There is no transmission of information between the lens and the camera. Exposure metering can be done in aperture priority mode or manually. G Nikkor type lenses can be closed with this adapter. E Nikkor type lenses are not compatible with this adapter! Note that depending on your 35mm lens calculation, some vignetting may occur on the Fujifilm GFX50s. This is not a reason for complaint!
