The Metabones Canon EF to Sony E Mount T Smart CINE Adapter (Mark IV) enables professional-quality lens mounting of Canon EF and EF-S lenses onto Sony E-Mount cameras whilst preserving full electronic functionality. Built from precision-machined brass with chromium plating on both camera and lens sides, this compact adapter features matte-black treatment and flocking material coatings inside to minimise internal reflection and maintain optical quality. The adapter supports autofocus, electronic aperture control, image stabilisation, and EXIF metadata recognition. A detachable tripod foot compatible with Arca Swiss and other standard ball heads provides additional stability for cinema and video work. Powered entirely by the camera body with no external power source required, the T Smart adapter represents the professional's choice for expanding a Sony E-Mount toolkit with quality Canon glass.
