Metabones Canon EF to BMPCC4K T CINE Speed Booster ULTRA 0.71x (MB_SPEF-m43-BTA)

The T CINE Speed Booster ULTRA 0.71x 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-stop increase for the camera over the lens's aperture range. This 0.71x adapter features Cinema EOS lens support for auto iris and servo zoom, and it also includes AF (autofocus) support which requires external 5V power via the micro-USB port. It also features a positive-lock mechanism for EF lenses.
