Metabones EF-E-mount T CINE Speed Booster ULTRA 0.71x

Metabones Canon EF Lens to Sony E -Mount T CINE Speed Booster ULTRA 0.71x

Metabones EF-E-mount T CINE Speed Booster allows users to adapt a Canon EF/EF-S-mount lens to a full-frame or APS-C Sony E-mount camera.

New optical design:  advanced 5-element/4-group optical design incorporating ultra-high index tantalum-based optical glass to achieve extraordinary optical performance with improved corner sharpness, distortion, and reduced vignetting.

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.
