Metabones Nikon G to Fuji X Speed Booster ULTRA 0.71x (Black Matt)
The Metabones Nikon G to Fuji X Speed Booster ULTRA 0.71x (Black Matt) allows Nikon F-mount lenses, including G-series, to be used on Fuji X-mount cameras while increasing the maximum aperture and widening the field of view. Featuring a patented aperture ring and advanced optical design, it delivers sharper images with enhanced contrast and resolution.
This high-performance lens adapter is designed for photographers seeking to use Nikon F-mount lenses on Fuji X-mount cameras. Its innovative Speed Booster technology reduces the crop factor of APS-C sensors while increasing the effective maximum aperture by one stop, resulting in brighter images with improved low-light performance.
At the core of this adapter is an advanced 5-element/4-group optical design, incorporating ultra-high index tantalum-based optical glass developed by Caldwell Photographic in the USA. This design increases MTF (modulation transfer function) for superior sharpness, reduces distortion, and minimizes vignetting across the frame.
The adapter features the industry's best aperture ring with 8-stop markings, providing precise, guess-free aperture control (patent granted). It is compatible with Nikkor G and F lenses, including non-AI and AI types, though certain E-series and specialty lenses are not supported.
Constructed from aluminum alloy and brass with a black matte satin finish, the adapter is both durable and stylish. A detachable tripod foot is included, compatible with Arca-Swiss, Markins, and Photo Clam ball heads, providing stable support during long shoots.
Tip: Before mounting a lens, ensure the aperture ring on the adapter is set to 7 (fully closed) to safely attach your lens.
