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

The Metabones Canon FD to Sony E-mount Speed Booster ULTRA 0.71x enhances your lens performance by increasing the maximum aperture by 1 stop, reducing crop factor, and delivering sharper corners with less distortion and vignetting. Featuring a 5-element/4-group optical design with ultra-high index tantalum-based glass, this adapter transforms full-frame Canon FD lenses for use on Sony E-mount cameras with exceptional clarity and contrast.

Boost the capabilities of your Canon FD lenses on Sony E-mount or other DX-sized mirrorless cameras with the Metabones Speed Booster ULTRA 0.71x. This advanced optical adapter condenses the light from full-frame FD lenses onto smaller APS-C or DX sensors, effectively reducing the crop factor from 1.5x to 1.07x while increasing the maximum aperture by one stop.

The Speed Booster ULTRA features an advanced 5-element/4-group optical design using ultra-high index tantalum-based glass developed by Caldwell Photographic in the USA, delivering exceptional sharpness, reduced vignetting, and minimized distortion. It works seamlessly with high-speed zooms and prime lenses, transforming, for example, a 50mm f/1.2 lens into a 35.5mm f/0.9 lens while maintaining excellent center-to-edge resolution.

Durable construction with a black matte finish ensures long-term reliability. A detachable tripod foot allows for Arca-Swiss, Markins, or Photo Clam ball head compatibility, making it ideal for both photography and cinematography applications. This adapter does not support electronic communication, so exposure and focus must be controlled manually.
