XL 0.64x optical adapter for Nikon F lenses for Blackmagic Design cameras with mico 4/3 mount, specifically for Blackmagic Pocket Cinema Camera 4K.

The BMPCC4K Speed Booster ULTRA 0.71x and XL 0.64x are similar to the standard Speed Booster MFT adapters (MB_SPNFG-m43-BM2 and MB_SPNFG-m43-BM3), but the optics have been redesigned to optimize the thickness of the 2.4 mm filter stack found in Blackmagic cameras, rather than the 4 mm of a standard four-thirds micro.

The BMPCC4K's Ultra 0,64x speed amplifier reduces the BMPCC 4K camera's clipping factor from 2.02x to 1.29x and produces the largest aperture optics currently available, with a maximum output aperture of f/0.8.
