The Metabones T Speed Booster ULTRA II adapts compatible Canon EF lenses for use on Sony E-mount APS-C and Super 35 cameras. Its 0.71× optical design is specified to provide approximately one stop of aperture gain and a wider field of view compared with using the same lens without the adapter.
Electronic contacts support features including aperture control, auto exposure and EXIF data transmission. Autofocus and stabilisation support depend on the specific camera, lens and firmware combination. Canon EF-S lenses are not supported, and full-frame Sony cameras use APS-C crop mode with this adapter.
