Le Smart Adapter Mark IV pour optique Canon EF vers monture Sony E/NEX de Metabones fixe votre optique à Canon à votre caméra Sony. Intelligemment pensé, il est nommé Smart Adapter en raison de sa transmission électronique entre la caméra et l’optique, communication lui permettant de fournir un contrôle de l’ouverture de l’optique automatique, de même que l’autofocus et le stabilisateur d’image.

This Smart Adapter^TM has the following features:

• True electronic integration of aperture diaphragm - let camera automatically choose aperture in P or S exposure modes, or dial in yourself on the camera body in A or M modes.
• Powered by camera body. No external power source required.
• Wide open button (opposite of depth-of-field preview function) makes manual focusing easy.
• The tripod foot is detachable and compatible with Arca Swiss, Markins, Photo cam ball heads.
