The Speed Booster Ultra 0.71x Adapter for Leica R-Mount Lens to Micro Four Thirds-Mount Camera from Metabones allows a Leica R-mount lens to be mounted onto a Micro Four Thirds-mount camera. While doing so, the adapter's optics help to maximize the connected lens's apparent angle of view while providing a 1-stop increase for the camera over the lens's aperture range.
