Under the hood of the Metabones Canon EF Lens to Fujifilm X T CINE Speed Booster ULTRA 0.71x Adapter lies an advanced optical design that sets a new standard for lens adapters. Featuring a sophisticated 5-element/4-group optical construction, this adapter utilizes ultra-high index tantalum-based optical glass to deliver exceptional optical performance. This results in sharper corners, minimized distortion, and reduced vignetting, ensuring your images maintain high quality from edge to edge.
The Speed Booster ULTRA boasts a magnification factor of 0.71x, effectively reducing the crop factor of mirrorless cameras with APS-C sensors, such as those with Sony E-mount and Fuji X-mount, from 1.5x to a more expansive 1.07x. This innovative design leverages cutting-edge materials, allowing it to be compatible with virtually all full-frame SLR lenses, regardless of exit pupil distance. As a result, it excels with professional-grade f/2.8 zoom lenses, transforming a 24-70mm f/2.8 into a 17-50mm f/2.0 and a 70-200mm f/2.8 into a 50-142mm f/2.0, delivering high-speed performance. Fixed focal length lenses, like a 50mm f/1.2, are converted into a 35.5mm f/0.9 lens, offering superb contrast and resolution across the entire image.
Optically, the adapter increases the maximum aperture by one stop, reaching an impressive f/0.9, and enhances the Modulation Transfer Function (MTF), making lenses 0.71x wider. Developed by Caldwell Photographic in the USA, this patented design ensures top-tier performance.
Electronically, the adapter facilitates seamless communication between Canon EF mount lenses and Fujifilm X-mount cameras. It supports phase-detection autofocus (PDAF) across a wide range of lenses by translating essential metadata between lens interfaces. The lens iris/aperture is controlled directly from the camera body, and the adapter is compatible with Fujifilm XF Teleconverters. It also supports optical image stabilization (IS) and smooth iris transitions with the latest Canon, Tamron, and Sigma lenses. Additionally, it adjusts focal length and aperture in EXIF data and can store EXIF information for one manual lens. Parallax correction is supported on X-Pro series rangefinders, and an LED indicator provides communication status. The adapter is powered by the camera body, eliminating the need for an external power source with most lenses.
Mechanically, the adapter features a patented positive-lock EF lens mount, flocking to reduce internal reflections, and a rubber gasket to protect the X-mount connection from dust and moisture. Constructed from aluminum alloy and brass with chromium plating, it boasts a satin surface finish. The detachable tripod foot is compatible with Arca Swiss Style ball heads and can be attached to a quick release plate via a 1/4"-20 screw, offering versatility and stability for professional use.
