This is especially critical at the extremely large apertures made possible by Speed Booster technology. 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. 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.
and Metabones are pleased to announce a new series of Speed Booster for Blackmagic Design Pocket Cinema Camera 4K (BMPCC4K).
Metabones Introduces a New Series of Speed Booster® for BMPCC 4K CameraĬaldwell Photographic Inc. For more information see the Metabones website. The Metabones Ultra 0.71x and XL 0.64x adapters are available now. The Arri PL version will only be available as an Ultra 0.71x, but the other mounts can accept either adapter, with the company claiming that many EF-S and DX lenses from Canon and Nikon can also be used. The adapters come in Ultra 0.71x and XL 0.64x versions, which reduce the crop factor in 4096 x 2160 4K video to 1.35x and 1.22x respectively. This means the new models aren’t compatible with other Micro Four Thirds cameras. Blackmagic uses a thinner layer of filters over the sensor of the BMPCC4K, compared to other MFT cameras, that can alter the effectiveness of the standard MFT adapter at wide apertures, the company claims. The company says it has redesigned the adapters to take account of the filter stack construction that Blackmagic uses on the sensor of this camera to ensure users get the same performance as other MFT users. The new adapters allow users to mount Nikon G, Canon EF, Canon EF Cine and Arri PL lenses onto the Micro Four Thirds camera. Lens mount adapter specialist Metabones has launched a new series of Speed Booster lens adapters especially designed for the Blackmagic Design Pocket Cinema Camera 4K (BMPCC4K).
