Metabones Leica R to BMPCC Speed Booster (Black Matt) 0.58
The Metabones Leica R to BMPCC Speed Booster (Black Matt) 0.58 allows Leica R lenses to be mounted on Blackmagic Pocket Cinema Cameras (BMPCC) and Micro Cinema/Studio 4K cameras with Micro Four Thirds mounts. By reducing the effective crop factor from 2.88 to 1.75, it transforms lenses into ultra-fast optics, increasing the maximum aperture up to f/0.74 and improving light gathering and shallow depth of field. Precision optics designed in the USA provide high MTF performance, while a detachable Arca-compatible tripod foot ensures stable mounting for professional use.
This adapter is specifically designed for Blackmagic cameras equipped with Micro Four Thirds mounts, including the original BMPCC, BMMCC, BMMSC 4K, and Blackmagic Studio Camera 4K. It allows photographers and filmmakers to mount Leica R lenses to these cameras while significantly enhancing lens performance.
By reducing the BMPCC's crop factor from 2.88 to 1.75, the Speed Booster effectively widens the field of view and increases the maximum aperture by approximately 1 2/3 stops. For example, a 50mm f/1.2 lens behaves like a 29mm f/0.74 lens, and the Sigma 18-35mm f/1.8 zoom becomes an ultra-fast 10.5-20.3mm f/1.0 lens with exceptional sharpness and contrast. This makes it ideal for low-light filmmaking and creating a shallow depth of field with cinematic quality.
The optical design, developed by Caldwell Photographic in the USA (patent granted), maximizes MTF performance and reduces distortion and vignetting. Precision-machined brass construction ensures a solid, play-free connection, while the matte-black interior minimizes internal reflections for optimal image quality. A detachable tripod foot is included, compatible with Arca Swiss, Markins, and Photo Clam ball heads for secure mounting during shoots.
