Canon EF Lens to Fujifilm X T CINE Speed Booster ULTRA 0.71x Adapter

About this product

The Metabones Canon EF Lens to Fujifilm X T CINE Speed Booster ULTRA 0.71x Adapter is a high-performance lens adapter designed for photographers and videographers using Canon EF mount lenses on Fujifilm X-mount mirrorless cameras. It features a 5-element/4-group optical design with ultra-high index tantalum-based glass, delivering sharp image quality with minimal distortion and vignetting across the frame. The adapter reduces the APS-C crop factor from 1.5x to 1.07x, effectively widening the field of view and increasing the maximum aperture by one stop—up to f/0.9—enhancing low-light performance. It supports phase-detection autofocus, electronic image stabilization, metadata transfer, and smooth iris control. Compatible with a wide range of Canon EF lenses, including professional zooms and prime lenses, it maintains full functionality with the camera body while preserving EXIF data and supporting parallax correction on X-Pro series rangefinders.
