    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 (i.e, by using 50mm lens, the actual focal length in BMCC is 32mm x 2.39 = 76.48mm), and Sigma’s new 18-35mm f/1.8 will become an 11.5-22.5mm f/1.1. (i.e, by using 18-35mm lens, the actual focal length in BMCC is from (11.5mm x 2.39 = 27.49mm) to (22.5mm x 2.39 = 53.78mm).

    Features:

    Industry's best aperture ring covers a 8-stop range, 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 11/3 stop. (with a maximum output aperture of f/0.80)
    Increase MTF.
    Makes lens 0.64x 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.
