PURPOSE:To control the selection between automatic elevation of a stroboscope and normal photography without making the whole constitution of a camera complex nor increasing the size by turning on and off an electromagnet for automatic focus adjustment and an electromagnet for automatic exposure in combination. CONSTITUTION:The AF electromagnet 7 and AE electromagnet 15 are turned on and off in combination to perform the selection control over strobe photography and normal photography, and when automatic elevation of a stroboscope, photography is performed because of low brightness, the brightness decision circuit of a shutter control circuit decides on automatic elevation of the stroboscope firstly and the electromagnet 7 is excited in response to the generation of a release signal. Then, the electromagnet 15 is also turned on with elevation of the automatic stroboscope decision signal at the same time to elevate a strobe. Then, the electromagnet 7 is turned off specific seconds later, turned on again after strobe charging is completed, and then turned off with a focus detection signal, thus completing automatic focus adjustment. The electromagnet 15 operates following up the electromagnet 7 during said period. |
