Metabones SPEF-BMCC-BT1 – Canon EF to Blackmagic Cinema Camera 2.5K MFT Speed Booster 0.64x

Designed for the Blackmagic Cinema Camera 2.5K (BMCC) with Micro Four Thirds mount: it reduces the full-frame crop factor from 2.39x to 1.53x, giving the camera a Super 35 field of view, and makes the lens 1 1/3 stops faster, up to f/0.80. It also works with the original Pocket Cinema Camera and the Digital Bolex D16 MFT.

• Increases MTF, patented optics by Caldwell Photographic (USA)

• On passive-mount cameras (BMCC 2.5K, Digital Bolex D16) external 5 V power via micro USB (not included)
• Detachable tripod foot compatible with Arca Swiss, Markins and Photo Clam; flocked interior against reflections

Note: It fits only Blackmagic cameras with Micro Four Thirds mount, not standard Micro Four Thirds cameras such as the GH4 (risk of damage). No autofocus and no EF-S lens support; the image circle does not cover a full-frame sensor.
