PURPOSE:To set a mode even in case of any photographing form by a simple operation by constituting so that a servo-type focusing control mode having a limiter and having no limiter is set in accordance with an exposure control mode of an automatic exposure control function. CONSTITUTION:In case when SW4-SW6 are set to a C (servo) position, an automatic focusing (AF) mode is set irrespective of an automatic exposure (AE) mode. An operation of AF in a state that a release button is not pushed is a servo-mode in which a limiter is not operated. When the release button is pushed in again, an SW3 is turned on, and the SW4 is at a position (c), therefore, a shutter release is executed. When the SW4-SW6 are set to a position (d), the AF mode is set irrespective of the AE mode. The AF mode becomes a one-shot mode and an output of an OR gate 34 is in H, therefore, the release operation can be executed. As a result, the mode can be set even in case of any photographing form of the AE and the AF. |
