Metabones T CINE Speed Booster XL 0.64x Adapter for Canon EF Lens to BMPCC 4K Camera

The T CINE Speed Booster XL 0.64x Adapter for Canon EF Lens to BMPCC 4K from Metabones allows a full-frame Canon EF-mount lens to be mounted onto a Blackmagic Design Pocket Cinema Camera 4K MFT-mount camera. While doing so, the adapter's optics help to maximize the connected lens's apparent angle of view while providing a 1.33-stop increase for the camera over the lens's aperture range. This CINE-type adapter features a positive-lock mechanism for EF lenses.
