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.

The Nikon mount version the new Speed Boosters features an improved version of Metabones’ unique manual G aperture adjustment mechanism, which has the same angular throw distance as earlier Nikon Ai/AiS lenses.  This improved version features a linearized f-stop adjustment as a function of aperture ring adjustment angle.  The mechanism is clickless in order to maximize its usefulness to cinematographers.

Both new Speed Boosters 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). In case of the 0.64x Speed Booster on BMCC, the original FOV of DX lenses is fully restored; a 180° fisheye remains a 180° fisheye.

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.
