Metabones Speed Booster Adaptor - Rollei QBM to E-Mount ULTRA

The Rollei QBM Lens to Sony E-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 Rollei QBM lens to be mounted to an APS-C format E-Mount camera and in doing so, increases the angle of view and increases the maximum aperture by approximately one f/stop.
