Infoseite // Zwei neue Metabone Speedbooster für die Pocket4K
Frage von Frank Glencairn:
The BMPCC4K Speed Booster ULTRA 0.71x and XL 0.64x are similar to the standard m43 Speed Booster adapters, but the optics have been re-designed to optimize for the filter stack thickness of the Blackmagic cameras, which is substantially thinner than that of standard m43 cameras.
The thickness of the camera’s filter stack is an important component of the overall optical design, and the re-designed optics ensure that both versions can achieve the same high performance as the Speed Booster versions for standard m43. This is especially critical at the extremely large apertures made possible by Speed Booster technology.
In addition to the new optical designs, the new series of Speed Boosters also features a longer tripod mount to perfectly match the height of the BMPCC4K camera body. This way the camera and the Speed Booster can be mounted firmly on the same quick release plate.
Both versions – the Speed Booster ULTRA 0.71x and XL 0.64x – are available with Nikon G lens mount, with Canon EF lens mount and with Canon EF CINE lens mount. The ARRI PL lens mount is available in ULTRA 0.71x version only. The Canon EF CINE lens mount creates a positive lock for a secure electronic connection, and together with the matching length of new the tripod mount, allows for a rock-solid mechanical setup, which is important when using follow focus attachments.
This new series of Metabones Speed Booster adapters is designed exclusively for Blackmagic Design Pocket Cinema Camera 4K (BMPCC4K). They cannot be attached to any other m43 cameras such as JVC, Olympus or Panasonic cameras.https://www.metabones.com/article/of/Sp ... r_BMPCC_4K
