Overview
The Metabones Sony A-mount to Fujifilm X-mount Speed Booster ULTRA 0.71x enhances lens performance by reducing crop factor and increasing aperture by 1 stop. Featuring advanced optical design, it delivers a wider field of view, improved sharpness, and superior low-light performance.
Design and Performance
The Metabones Sony A-mount to Fujifilm X-mount Speed Booster ULTRA 0.71x (Black Matt) is a high-performance optical adapter designed to maximize the potential of Sony A-mount lenses when used on Fujifilm X-mount cameras. Featuring an advanced 5-element/4-group optical design with ultra-high index tantalum-based glass, this Speed Booster significantly enhances image quality with sharper corners, reduced distortion, and minimized vignetting.
With a 0.71x magnification factor, the adapter effectively reduces the APS-C crop factor from 1.5x to approximately 1.07x, delivering a wider, near full-frame field of view. Additionally, it increases the maximum aperture by 1 stop, improving low-light capability and enabling shallower depth of field.
The Speed Booster ULTRA is optimized for both professional zoom and prime lenses, delivering excellent contrast and resolution across the entire frame. For example, a fast 50mm f/1.2 lens can achieve an effective look similar to a 35.5mm f/0.9, offering exceptional creative flexibility.
Built with precision engineering, the adapter ensures a secure and stable fit. It also includes a detachable tripod foot compatible with Arca-Swiss, Markins, and Photo Clam ball heads for stable mounting during professional shooting setups.
