The New Speedboosters by Metabones for Blackmagic
The original Metabones Speedboosters are available in several versions adapting various full-frame lenses to NEX, micro 4/3, and Fuji-X cameras. They offer a magnification factor of 0.71X; meaning the lens focal length changes by this factor and the aperture increases by one stop. For example, a 100mm f/2.8 full-frame lens becomes a 71mm f/2.0 lens when mounted on an NEX camera by a Speedbooster.
For people shooting video on micro 4/3 and APS-C size sensors, the Speedboosters give them an opportunity to shoot with full-frame lenses and reduce the ‘crop factor’ associated with shooting on the smaller sensor size. The also increase the aperture of the lens, letting in more light.
