Metabones Nikon G to BMPCC Speed Booster (Black Matt)

Nikon-G/F to Micro-4/3 mount Speed BoosterTM adapters designed exclusively for the Blackmagic Pocket Cinema Camera (BMPCC). 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 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, 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.

Key Features

  • Industry's best aperture ring covers a 8-stop range with half-stop markings, clearly indicating actual number of f-stops. No more guesswork! (Patent pending).
  • Compatible to both Nikkor G lens & F lens (include non-AI & AI lens mounts).
  • Increase maximum aperture by 1 2/3stop. (with a maximum output aperture of f/0.74)
  • Increase MTF.
  • Makes lens 0.58x wider.
  • Click-less manual G aperture ring.
  • Optics designed by Caldwell Photographic in the USA (patent pending).
  • The tripod foot is detachable and compatible with Arca Swiss, Markins, Photo cam ball heads.

Tips: Before mounting your lens to the adaptor, please make sure that the f-stop of aperture ring on the adaptor is turned to "7" (i.e. mounting your lens to the adaptor while only the aperture ring in the adaptor is full closed.).

Remark: This mount is manual aperture control. It does NOT support electronic aperture control.
