The Metabones Canon EF to Fujifilm X-mount T CINE Speed Booster ULTRA 0.71x Mark II is a premium optical and electronic adapter that maximizes the performance of your Canon EF lenses on Fujifilm X-mount cameras. Its advanced 5-element/4-group optical design, incorporating ultra-high index tantalum-based optical glass by Caldwell Photographic in the USA, increases the lens’s maximum aperture by 1 stop and widens the field of view by 0.71x, providing superior sharpness, contrast, and reduced vignetting.

Fully electronic, this adapter supports phase-detection autofocus (PDAF) across compatible lenses, optical image stabilization (IS), smooth iris control, and stores EXIF data including lens name, focal length, and aperture. Parallax correction is supported on the X-Pro series rangefinders, and an LED indicator shows communication status. Mechanical features include a patented positive-lock EF lens mount, flocked interior to reduce internal reflections, a dust-resistant rubber gasket, and a detachable Arca Swiss-compatible tripod foot. Constructed from aluminum alloy and brass with chromium plating and a satin finish, it ensures durability and smooth handling.
