Looking for the ideal adapter for Canon EF to Sony E-Mount Lenses? Look no further than the Metabones Speed Booster Ultra. This adapter has optics that maximize the connected lens’ angle of view while allowing a 1-stop increase for the camera over aperture range of the lens. Able to capture the center of a projected image, the angle of view narrows to create a crop factor to project the perfectly sized image.
