Metabones Canon EF Lens to Fuji X mount T Speed Booster ULTRA 0.71x

Metabones EF-X-mount T Speed Booster ULTRA 0.71x allows the Canon EF mount lens to Fujifilm X-mount camera.

The Speed Booster ULTRA has a magnification of 0.71x, so it effectively reduces the crop factor of mirrorless cameras with DX-sized sensors, such as Sony E-mount and Fuji X-mount cameras, from 1.5x to 1.07x.

Optical

• Increase maximum aperture by 1 stop. (with a maximum output aperture of f/0.9).
• Increase MTF.
• Makes the lens 0.71x wider.
• Advanced 5-element/4-group optical design incorporating ultra-high index tantalum-based optical glass by Caldwell Photographic in the USA (patent granted).

Electronic

• Canon EF mount lens to Fujifilm X-mount camera.
• Autofocus. Phase-detection autofocus (PDAF) is supported no matter which AF lens is used. Adapters support PDAF by translating pertinent metadata about the optics between the lens interfaces. In this way, broad support for the widest range of lenses is made possible.
• Lens iris/aperture is set by the controls on the camera body.
• Optical image stabilization (IS) lens support.
• Smooth iris support with the latest Canon (2009+), Tamron (SP series 2013+), and Sigma (2016+) lens models.
• Focal length and aperture are adjusted in EXIF (see note 3).
• Store EXIF data (lens name, focal length, and maximum/minimum aperture) for one manual lens in the adapter.
• Parallax correction on the X-Pro series rangefinders is also supported.
• LED indicator shows communication status.
• Powered by the camera body. With most lenses, no external power source required.

Mechanical

• Flocking to reduce internal reflection.
• The rubber gasket protects the X-mount connection from dust and moisture.
• Aluminum alloy and brass construction with chromium plating.
• Satin surface finish.
• Detachable tripod foot compatible with Arca Swiss Style ball head, such as Markins and Photo Clam or attach to quick release plate by a 1/4″-20 screw.
