Metabones Speed Booster Adaptor - ALPA to X-Mount ULTRA MB_SPALPA-X-BM2

The ALPA Lens to Fujifilm X-Mount Camera Speed Booster ULTRA from Metabones improves upon the original Metabones Speed Booster with a 5 element/4 group optical design that incorporates ultra-high refractive index tantalum-based glass for improved sharpness and reduced distortion and vignetting. The Speed Booster ULTRA allows a full frame ALPA lens to be mounted to an APS-C format X-Mount camera and in doing so, increases the angle of view and increases the maximum aperture by approximately one f/stop.
