Abstract
A camera construction is provided which embodies a shutter means, a trigger means for actuating the shutter means, and a pair of iris blades mounted for simultaneous movement in opposite directions to vary the configuration of an iris opening which is defined thereby and is aligned with the camera lens. The movement of the iris blades is responsive to the independent manipulation of a plurality of manual controls separate from the trigger means. The permissible range of movement of the iris blades by each manual control is unequal.
