Metabones Canon EF - X-mount T CINE Speed Booster Ultra (0.71x)

Professional Cinema Optics for Fujifilm X-Mount

The Metabones Canon EF to X-mount T CINE Speed Booster Ultra (0.71x) is a precision-engineered optical adapter designed for professional filmmakers and photographers. By utilizing a sophisticated 5-element optical design, this adapter reduces the crop factor of APS-C cameras from 1.5x to 1.07x, effectively mimicking the field of view of a full-frame sensor.

Enhanced Light Transmission and Sharpness

Equipped with ultra-high index tantalum-based glass, the Speed Booster Ultra increases the maximum aperture of your lens by 1 stop. This allows for better low-light performance and a more pronounced bokeh effect. The optical design is optimized to maintain edge-to-edge sharpness and minimize chromatic aberration.

CINE-Style Positive-Lock Mount

Unlike standard adapters, the CINE version features a positive-lock EF mount. This mechanism ensures that the lens is held firmly in place without any play or rotation, which is critical when using follow-focus systems or heavy cinema glass. The weather-resistant rubber gasket protects the camera sensor from dust and moisture.

• Electronic Control: Full support for aperture control from the camera body and image stabilization (IS).
• EXIF Data: Translates lens information into the camera metadata for easy post-production tracking.
• Reflective Coating: Internal flocking prevents ghosting and flares caused by internal reflections.
• Detachable Tripod Foot: Arca-Swiss compatible foot for secure mounting on tripods and rigs.
