ABSTRACT:
A fast-opening shutter includes an actuating member moveable in a one direction for setting an aperture stop and in the opposite direction for setting focus. The camera shutter is then driven to open against the stop independently of movement of the actuating member. According to more specific features, the actuating member first sets the stop and then focuses a camera optical element. After the exposure is completed, the mechanism is reset by further movement of the actuating member in the second or opposite direction.
