Nikon G to BMPCC4K Speed Booster ULTRA 0.71x (2019) Metabones

Podrobný popis

The new BMPCC4K Speed Booster ULTRA 0.71x and XL 0.64x variants are based on the existing MFT models, but are optimized for the BMPCC4K camera filter set, which is considerably smaller in thickness than standard cameras with this mount. In addition to the modified optical system, they also offer a longer tripod foot - for perfect alignment with the BMPCC4K camera body - guaranteeing a solid connection between the camera body and the Speed Booster adapter with the quick release plate. Both models - the Speed Booster ULTRA 0.71x and XL 0.64x - are available in Nikon G, Canon EF and Canon EF CINE mount variants. In addition, the ULTRA 0.71x is also available in the ARRI PL version, on sale from 8/2019.

The new BMPCC4K Speed Booster ULTRA 0.71x and XL 0.64x variants are based on the existing MFT models, but are optimized for the BMPCC4K camera filter set, which is considerably smaller in thickness than standard cameras with this mount. The sensor filters are an important part of the camera's overall optical system and the redesigned optics of the new adapters thus guarantee maximum image quality, especially at extreme aperture openings. In addition to the modified optical system, they also offer a longer tripod foot - for perfect alignment with the BMPCC4K camera body - guaranteeing a solid connection between the camera body and the Speed Booster adapter with the quick release plate



Both models - the Speed Booster ULTRA 0.71x and XL 0.64x - are available in Nikon G, Canon EF and Canon EF CINE mount variants. In addition, the ULTRA 0.71x model is also available in the ARRI PL version. The new Metabones Speed Booster range of adapters is designed specifically for the Blackmagic Design Pocket Cinema Camera 4K and cannot be used in combination with other MFT mounted cameras (JVC, Olympus or Panasonic)..

Speed Booster ULTRA 0.71x for BMPCC4K
The Speed Booster ULTRA 0.71x for BMPCC4K uses advanced optics consisting of six lenses in four groups including high refractive index tantalum glass elements. The new variant has been designed specifically for the Blackmagic Pocket Cinema Camera 4K for maximum image quality and compatibility with FF (as well as DX and APS-C) lenses, from vintage film to the latest lenses from all brands

Speed Booster adapters take advantage of the capabilities of advanced materials and patented technologies from US-based Caldwell Photographic to improve the transmission characteristics of the camera's entire electro-optical imaging system. The adapter uses extremely high refractive index glass for superior optical performance, including reducing focal length and increasing lens mounted luminosity and sensor coverage, as well as improving modulation transfer function. A noticeable improvement can be observed especially in the centre of the image, with a slight improvement also occurring in the peripheral parts. In addition to Full-Frame lenses for SLR cameras, the new Speed Booster ULTRA 0.71x also handles most DX and APS-C format lenses and improves the modulation transfer function of even high-performance optics such as the Zeiss Otus series!



The Speed Booster adapter guarantees an improvement in the optical performance of the lens used: even at the maximum aperture of f/0.90 (with an f/1.2 lens) the adapter provides a sharp, high-contrast image throughout, at f/1.0 the optical performance is comparable (or higher) to the best photographic lenses at optimum aperture settings, and at f/2.0 it outperforms most photographic optics. Vignetting at the maximum aperture of f/0.9 does not exceed one aperture number, and at f/2.82+ there is no vignetting at all. Rectilinear distortion is less than 0.7%
