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

The Metabones Canon FD to Fuji X-mount Speed Booster ULTRA 0.71x enhances lens performance by increasing aperture by one stop and widening the field of view. Featuring advanced optical design and durable brass construction, it delivers sharper images with reduced distortion and vignetting.

The Metabones Canon FD to Fuji X-mount Speed Booster ULTRA 0.71x (Black Matt) is a high-performance optical adapter designed to bring legacy Canon FD lenses to Fujifilm X-mount cameras while significantly improving their capabilities. Incorporating a patented 5-element/4-group optical design with ultra-high index tantalum-based glass from Caldwell Photographic, this Speed Booster delivers exceptional image quality with improved sharpness, reduced distortion, and minimized vignetting.

With a 0.71x magnification factor, the adapter effectively reduces the crop factor of APS-C cameras from approximately 1.5x to 1.07x, providing a wider field of view closer to full-frame performance. At the same time, it increases the maximum aperture by one stop, allowing for enhanced low-light shooting and greater depth-of-field control.

Engineered for professional use, the adapter features precision-machined brass mounts with chromium plating combined with an aluminum alloy body for durability and smooth mounting. The satin black finish matches modern camera systems, while the detachable Arca-type tripod foot ensures stable support for heavier lens setups and compatibility with leading tripod systems such as Arca Swiss, Markins, and Photo Clam.

Designed to maintain the correct registration distance, the Speed Booster ensures accurate infinity focus and optimal performance with a wide range of full-frame lenses, including fast primes and professional zoom lenses.
