Metabones Nikon F, G-Type Lens to L-Mount Speed Booster ULTRA 0.71x

The Nikon F, G-Type to L-Mount Speed Booster ULTRA 0.71x from Metabones is designed for the APS-C crop mode in full-frame L-mount cameras and has a magnification of 0.71x, effectively reducing crop factor from 1.5x to 1.07x. The Speed Booster ULTRA performs extremely well with professional-grade f/2.8 zoom lenses and on high-speed fixed focal length lenses, such as a 50mm f/1.2 will be transformed to a 35.5mm f/0.9 lens with even contrast and resolution from the center all the way to the edges of the image.
