Metabones EF - E Mount Adapter
The Metabones EF - E Mount Adapter is a lens adapter that allows EF lenses to be mounted on Sony E-mount cameras. It is referred to as a "Smart Adapter" because it retains electronic communication between the camera and lens and therefore provides automatic aperture control, EXIF data, image stabilization, and autofocus. The adapter is powered by the camera body, so no external power source is required.
