Abstract: A low inertial electronic camera shutter is disclosed wherein a ring member coaxially aligned with a bore in a housing pivotally moves a plurality of shutter blades in registry with the bore between open and closed positions for controlling light radiation through the bore. In accordance with the invention, a low inertial means including a longitudinal wire member connected between the ring member and the frame at a pivot point thereon, drives the plurality of shutter blades between the two positions in response to a pulse applied to a solenoid having an armature connected to the wire member at a point thereon to amplify armature movement. The camera shutter includes a flash means including an electrical contact switch actuated by the ring member when the shutter blades are driven into the open position.
