Always Enhance and Never Degrade the Performance of the Attached Master Lens
Like the ULTRA series for Mirco Four-Thrids mount, the new BMPCC4K Speed Booster® ULTRA 0.71x uses an advanced 6-element 4-group optical design incorporating ultra-high index tantalum-based optical glass. However, the new design is specifically optimized for the BMPCC4K sensor and filter stack, and as a result, achieves an astonishing level of performance that sets a new standard for focal reducers.
Metabones ARRI PL to BMPCC4K 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.
The BMPCC4K Speed Booster ULTRA 0.71x reduces the crop factor of the BMPCC 4K camera from 2.02x to 1.43x and produces the largest aperture optics currently available, with a maximum output aperture of f/0.9.
New professional Mount-Rod Support Kit is also available (not included), which is compatible with all Metabones adapters with tripod foot.
