Metabones BMPCC Speed Booster

Nikon-G/F to Micro-4/3 mount Speed Booster adapter is designed exclusively for the Blackmagic Pocket Cinema Camera (BMPCC) with an MFT mount. 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, 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!

Advanced Optical Design
The Speed Booster uses an advanced 6-element optical design incorporating ultra-high index glass to achieve extraordinary optical performance at record-breaking apertures. In addition to increasing lens speed and field of view, the new Speed Booster significantly increases the lenses MTF (Modulation Transfer Function). There is a dramatic performance enhancement near the center of the image, but there is also a moderate performance improvement in the outer parts of the image as well.

Compatible with Nikon FX and DX Lenses
It can be used with FX and DX lenses, including DX lenses with fixed lens hoods (e. g. Nikon 10.5mm/2.8 Fisheye or Sigma 8-16mm/4.5-5.6 Ultra-wide Zoom).
