Metabones Nikon F/G to Cinema Camera - Speed booster
Elle vous permet d'adapter vos objectifs Nikon sur la Cinema Camera 2.5K de Blackmagic, avec la technologie Speed Booster réduisez le crop factor.
Nikon-G/F to Micro-4/3 mount Speed BoosterTM 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. For example, a 50mm f/1.2 becomes a 32mm f/0.80, and Sigma's new 18-35mm f/1.8 will become an 11.5-22.5mm f/1.1.
