Nikon-G/F to Micro-4/3 mount Speed Booster^TM  adapters designed exclusively for the Blackmagic Pocket Cinema Camera (BMPCC), Blackmagic Micro Cinema Camera(BMMCC) and Blackmagic Micro Studio Camera 4K(BMMSC 4K). Note that this new 0.58x Speed Boosters will only attach to BMPCC equipped with a Micro-4/3 mount.  They cannot be attached to standard Micro 4/3 and BMPCC4K cameras.

The new 0.58x Speed Booster reduces the crop factor of the BMPCC from 2.88x to 1.75x, and produces the largest aperture optics currently available, with a maximum output aperture of f/0.74.  For example, a 50mm f/1.2 now becomes a 29mm f/0.74 (i.e, by using 50mm lens, the actual focal length in BMPCC is 29mm x 3.02 = 87.58mm), and the Sigma 18-35mm f/1.8 becomes the world’s fastest zoom lens at 10.5-20.3mm f/1.0 with stunningly sharp performance. (i.e, by using 18-35mm lens, the actual focal length in BMPCC is from (10.5mm x 3.02 = 31.71mm) to (20.3mm x 3.02 = 61.31mm). More detail about crop factors, please refer to the table below:
