Leaf Shutter

A leaf shutter comprises a small number of identical overlapping metal blades, called leaves, that open and close in order to expose a photograph. It is usually situated close to the iris within the camera lens. Depending on the way the shutter is arranged it is referred to as ‘between-lens’ or ‘behind the lens’. Common leaf shutters include the German Compur and Prontor, and the Japanese Copal, Citizen and Seikosha.
