Abstract
PURPOSE:To execute photographing of proper exposure by a simple operation, by executing a focus lock for an object to be photographed, and a manual memory of its photometric value, by means of a single operation. CONSTITUTION:When a focus lock switch S1 is closed in the course of use of an autofocus, a lock device 1 is operated, and an autofocus device 2 positions a lens at a focused point for an object to be photographed in that case. On the other hand, a signal from S1 is applied to a memory lock device 4 through a gate 3, and a photometric output regarding the object to be photograhed, whose focus has been locked is stored in a storage device 5. Subsequently, an exposure control device 6 controls the exposure in accordance with this stored value. Also, when a memory lock switch S2 is closed, the device 4 is operated irrespective of the device 1, and the photometric output is stored.
