Camera system
Abstract
A camera system comprises a selector, an operable switch, a changing circuit and an inhibiting circuit. The selector selects one of a plurality of exposure lines. The changing circuit changes a combination of the aperture value and the shutter speed value determined by both the selected exposure line and a brightness value in response to the operation of the operable switch. The inhibiting circuit inhibits the operation of changing circuit when a predetermined exposure line is selected by the selector. i In the camera system, a photographer may only select the exposure mode through the operable switch in accordance with his intention and purpose in photography, and then the change of the exposure combination is inhibited in a certain exposure mode.
