Metabones has announced the release of the NF – GFX mount Expander 1.26x, a new adapter that allows Nikon F-mount lenses to be mounted to Fuji G-mount (GFX) camera systems while also magnifying the image circle by 1.26x, making it so the lenses retain their native diagonal field of view across formats.
The adapter, which is constructed of an aluminum alloy and chromium-plated brass, features a detachable Arca-Type tripod foot and is comprised of five optical elements in three groups, including elements made of ‘ultra-high index Lanthanum-based optical glass as well as one element made of fused silica.’ The adapter uses Metabones’ manual G aperture adjustment, which uses ‘the same angular throw distance as earlier Nikon Ai/AiS lenses, which features a linearized f-stop adjustment as a function of aperture ring adjustment angle.’ The mechanism is also clickless for convenience when using it for cinematography.
Using examples provided by Metabones, the NF – GFX mount Expander 1.26x would effectively turn a 24–70mm F2.8 lens into a 30–88mm F3.5 lens, and a 70–200mm F2.8 lens into an 88–252mm F3.5 lens. Since this is only a focal extender, the lenses will lose 2/3 a stop of light, meaning F1.4 lenses drop to F1.8 and F2.8 drop to F3.5.
In addition to Nikkor DX lenses and third-party APS-C lenses will likely have strong vignetting with using them with the adapter and a number of other lenses have limitations, as noted by Metabones in the below graphic:
