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

Maximize Your Full-Frame Lenses on Fujifilm X-Mount

The Metabones Canon EF to X-mount T Speed Booster ULTRA (0.71x) is a high-performance lens adapter that allows you to mount full-frame Canon EF-mount lenses onto Fujifilm X-mount camera bodies. By utilizing advanced optics, this adapter condenses light from the lens onto the APS-C sensor, effectively increasing the maximum aperture by one stop and widening the field of view to mimic a full-frame perspective.

Advanced Optical Engineering

Designed by Caldwell Photographic, the Speed Booster ULTRA features a sophisticated 5-element, 4-group optical design. It incorporates ultra-high index tantalum-based glass to improve MTF (Modulation Transfer Function), ensuring exceptional sharpness, reduced distortion, and minimal vignetting across the entire frame.

Seamless Electronic Integration

This adapter provides a complete electronic interface between the lens and the camera. It supports autofocus, electronic aperture control, and the transmission of EXIF data to the camera. The adapter is powered directly by the camera body, requiring no external power source for operation.

• Magnification: 0.71x
• Aperture Increase: 1 stop
• Optical Design: 5 elements in 4 groups
• Tripod Foot: Removable Arca-Swiss compatible type

Note: This adapter is designed for Canon EF-mount lenses. EF-S lenses are not compatible. While most lenses are supported, autofocus performance may vary depending on the specific lens and camera body combination.
