The T Cine Speed Booster ULTRA 0.71x II from Metabones allows a full-frame Canon EF lens to be mounted to an APS-C format FUJIFILM X-mount camera and in doing so, increases the angle of view by .71x and increases the maximum aperture by approximately one f/stop. Incorporated in its design is an ultra-high refractive index tantalum-based glass for improved sharpness and reduced distortion and vignetting. The Speed Booster condenses light from the lens and projects it onto the APS-C sensor allowing the sensor to utilize all of the lens's light and effectively reduces the crop factor of an APS-C E-mount camera from 1.5x to 1.07x, producing a full-frame angle of view with an APS-C sensor. A corresponding increase in the maximum aperture of one f/stop makes the lens more effective in low-light situations and able to create a shallow depth of field. An LED indicator displays communication status. Additionally, this adapter has a tripod foot that is compatible with Arca Swiss, Markins, and Photo Clam ball heads.

Metabones MB_SPEF-X-BT3 Overview
The T Cine Speed Booster ULTRA 0.71x II design incorporates ultra-high index tantalum-based optical glass for enhanced optical performance with improved corner sharpness and reduced distortion and vignetting. This glass technology and optical design perform extremely well with professional-grade f/2.8 zoom lenses and high-speed fixed focal length lenses such as a 50mm f/1.2 which will perform as a 35.5mm f/0.9 lens with high contrast and resolution from the center to the edges of the image.
Precise fit and solid connection—lens has no play, gap, or wiggling when mounted on a speed booster and no adjustments are required to fit your lens. The speed booster is constructed with aluminum alloy and brass with chromium plating.
The T Cine Speed Booster ULTRA 0.71x II uses a matte-black treatment to keep internal reflection to a minimum in order to maintain the maximum optical quality possible with the lens.
Designed to reach infinity focus while maintaining the correct registration distance required to maintain optical quality of CRC lenses or lenses with floating elements.
The T Cine Speed Booster ULTRA 0.71x II features a detachable tripod foot, which compatible with Arca Swiss, Markins, Photo Clam ball heads. The booster may attach to a quick release plate or tripod using a 1/4"-20 screw.
