Metabones Canon FD to X-mount Speed Booster ULTRA 0.71x (Black Matt)

The Metabones Canon FD to FUJIFILM X-Mount Speed Booster ULTRA 0.71x reduces crop factor while increasing the maximum aperture by 1 stop, giving your FD lenses a wider field of view and enhanced optical performance. Crafted from aluminum and brass with a satin finish, it features a detachable Arca-type tripod foot and advanced 5-element/4-group optics for sharp, high-contrast images.

The Metabones Canon FD to FUJIFILM X-Mount Speed Booster ULTRA 0.71x is designed to maximize the performance of your vintage Canon FD lenses on modern FUJIFILM X-mount mirrorless cameras. Using an advanced 5-element/4-group optical design with ultra-high index tantalum-based glass, this Speed Booster increases the effective angle of view by 0.71x while providing a one-stop boost in maximum aperture. This results in brighter, faster lenses with improved MTF, sharper corners, reduced distortion, and minimized vignetting.

The adapter reduces the crop factor of APS-C X-mount cameras from 1.5x to 1.07x, effectively turning professional-grade zooms or prime lenses into higher-speed equivalents. For example, a Canon 50mm f/1.2 lens becomes a 35.5mm f/0.9 lens, preserving excellent resolution across the frame. Its aluminum alloy and brass construction with chromium plating ensures durability, and a rubber gasket protects the X-mount from dust and moisture. The included detachable Arca-type tripod foot provides secure mounting to Arca-Swiss, Markins, and Photo Clam ball heads.
