Metabones MBSPLR-L-BM1 Overview
The Leica R-Mount 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.
Please note, the rear element of the lens cannot protrude from the flange more than 10.5mm and some lenses will require modification in order to fit on the adapter.
