Description
The Metabones Canon EF Lens to Sony NEX Smart Adapter (Mark IV) from Metabones attaches a Canon EF lens to a Sony E-mount mirrorless camera. 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 stabilisation and autofocus. The adapter is powered by the camera body, so no external power source is required. The Mark IV provides the same functions as the Mark III but provides optimised performance and an improved internal structure.
