Metabones Nikon G to X Mount Speed Booster ULTRA 0.71x (MB_SPNFG-X-BM2)

The Nikon F-Mount G Lens to Fujifilm X-Mount Camera Speed Booster ULTRA from Metabones improves upon the original Metabones Speed Booster with a 5 element/4 group optical design that incorporates ultra-high refractive index tantalum-based glass for improved sharpness and reduced distortion and vignetting. The Speed Booster ULTRA allows a full frame Nikon F-Mount G lens to be mounted to an APS-C format X-Mount camera and in doing so, increases the angle of view and increases the maximum aperture by approximately one f/stop. It is compatible with NIKKOR F mount and F Mount G lenses including AI and non-AI mounts.
