New Speed Booster Adapters for BMCC and BMPCC

Metabones has introduced two new versions of its Nikon-F to Micro Four Thirds mount Speed Booster adapters. This time they are designed specifically for the Blackmagic Cinema and Pocket Cinema cameras. The original Metabones Speedboosters are available in several versions adapting various full-frame lenses to NEX, micro 4/3, and Fuji-X cameras. They offer a magnification factor of 0.71X; meaning the lens focal length changes by this factor and the aperture increases by one stop.

The new 0.64x Speed Booster reduces the full-frame crop factor of the Blackmagic Cinema Camera from 2.39x to 1.53x. In addition, the speed of any attached lens is increased by 1 1/3 stops, with a maximum output aperture of f/0.80. The new 0.58x Speed Booster reduces the crop factor of the Blackmagic Pocket Cinema Camera from 2.88x to 1.75x, with a maximum output aperture of f/0.74. So for example on the Pocket Cinema Camera, a 50mm f/1.2 now becomes a 29mm f/0.74, and the Sigma 18-35mm f/1.8 becomes a 10.5-20.3mm f/1.0.
