Усилитель скорости Nikon G Lens to Blackmagic Pocket Cinema Camera Speed Booster от компании Metabones позволяет установить объектив Nikon G на Pocket Cinema Camera и при этом увеличить угол обзора и максимальную диафрагму.
В 6-элементной оптической конструкции Speed Booster используется стекло со сверхвысоким индексом, что позволяет достичь идеальных оптических характеристик на самых больших диафрагмах. Он увеличивает максимальную диафрагму на 1 2/3 стопа с максимальной диафрагмой f/0,74 и уменьшает кроп-фактор с 2,88x до 1,75x.
Speed Booster не только увеличивает поле зрения и скорость объектива, но и повышает ЧКХ объектива, т.е. точность передачи деталей от объекта на матрицу камеры. Увеличение ЧКХ проявляется как в углах, так и в центре изображения.
В Speed Booster встроено кольцо диафрагмы без щелчка - необходимая функция для кинематографистов, а также съемное крепление для штатива типа Arca.
Nikon-G/F to Micro-4/3 mount Speed BoosterTM adapters designed exclusively for the Blackmagic Pocket Cinema Camera (BMPCC), Blackmagic Micro Cinema Camera(BMMCC) and Blackmagic Micro Studio Camera 4K(BMMSC 4K). 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 and BMPCC4K 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 (i.e, by using 50mm lens, the actual focal length in BMPCC is 29mm x 3.02 = 87.58mm), 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. (i.e, by using 18-35mm lens, the actual focal length in BMPCC is from (10.5mm x 3.02 = 31.71mm) to (20.3mm x 3.02 = 61.31mm). More detail about crop factors, please refer to the table below:

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.

Since its inception, Metabones has been designing and manufacturing lens adapters recognized among professionals and enthusiasts as leaders in design and workmanship.
Contrary to the popular trend of other factories using an aluminum ring painted black on the camera-body-side, we instead take no short-cut but use precision-machined brass with chromium plating on both the camera-body and the lens sides of our adapters, in order to ensure smooth mounting, great appearance, and durability. The lens side of the adapter features a strong leaf-spring structure, strengthening the adapter-lens connection and ensuring tightness of the lens in order to reduce wear and prevent focus errors and optical alignment issues from appearing.
Metabones uses matte-black treatment to keep internal reflection to a minimum in order to maintain the maximum optical quality possible with the lens.
All Metabones Adapters follow this tradition of uncompromising precision, robust build quality and outstanding finish. Our new Smart AdapterTM series of products add industry-leading electronic interfacing technology from Canada, with true electronic control of the lens' aperture directly from the camera body.
