METABONES INTRODUCES SPEED BOOSTERS FOR NIKON G TO BLACKMAGIC CINEMA CAMERA AND BLACKMAGIC POCKET CAMERA

Metabones® and Caldwell Photographic Inc. are pleased to jointly announce two new Nikon-F to Micro-4/3 mount Speed BoosterTM adapters designed exclusively for the Blackmagic 2.5k Cinema Camera (BMCC) and the Blackmagic Pocket Cinema Camera (BMPCC), with magnifications of 0.64x and 0.58x, respectively. Both new Speed Boosters use advanced 6-element optical designs incorporating ultra-high index glass to achieve extraordinary optical performance at record-breaking apertures. 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 Sigmas new 18-35mm f/1.8 will become an 11.5-22.5mm f/1.1.

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 worlds fastest zoom lens at 10.5-20.3mm f/1.0 with stunningly sharp performance.

In addition to increasing lens speed and field of view, both of the new Speed Boosters significantly increase the lens MTF. For both the 0.58x and 0.64x versions 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. This is especially impressive when you consider that the Speed Booster MTF is evaluated at f/0.80 and f/0.74, respectively, while the native 50mm lens is evaluated at f/1.2.

Nikon mount versions of both new Speed Boosters feature 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.

The new Speed Boosters will be available starting in December 2013 from the Metabones website and its worldwide dealer network for $489 plus shipping and applicable taxes and duties.
