Canon EF to BMCC mount T Speed Booster adapters designed exclusively for the Blackmagic 2.5k Cinema Camera (BMCC). Note that the new Speed Boosters will only attach to Blackmagic cameras equipped with a Micro-4/3 mount. They cannot be attached to standard Micro 4/3 cameras. The new 0.64x Speed Booster reduces the full-frame crop factor of the BMCC from 2.39x to 1.53x, thus effectively transforming it into a Super-35 format cine camera. In addition, the speed of any attached lens is increased by 11/3 stops, with a maximum output aperture of f/0.80.
