Abstract

PURPOSE: To prevent the wasteful consumption of batteries by obviating lighting of a subject lighting lamp when the subject is bright even while a strobe is in use.
CONSTITUTION: When a switch 4 goes on in strobe takin, voltage is applied to comparators 24, 35 and the subject lighting device and home position locking device are abled. When the subject luminance is LV4 or less, the output of the circuit 24 becomes H and when a transistor (TR)26 goes ON, the subject lighting lamp 29 lights only at the search scanning, thereby lighting the subject. If the subject luminance is larger than EV4 even when the strobe is in use, the output of the circuit 4 becomes L and the TRs26 and 27 go OFF and TR28 goes ON so that the output of the circuit 35 becomes L and the home position locking device is disabled. The lamp 29 does not go on either.
