Abstract

PURPOSE: To make possible the controlling of correct exposure based on the photographer's intention in the photographing-mode-selectable camera by displaying the exposure set value when this reaches threshold and shifting the exposure control mode.
CONSTITUTION: Film sensitivity is set by an ASA sensitivity input dial 10 and exposure time by an exposure time setting dial 24 and the maximum and minimum apertures based on the composition intention are set by maximum- and minimum- aperture setting knobs 20, 22. When a fully automatic selection switch 30 is next operated, the shutter-second-time-priority mode is set. The aperture value is operated by the operations based on the programs of the ROM in the camera body 2. When the results thereof become more or less than the threshold value determined by the preset maximum and minimum aperture values, the exposure threshold is displayed in the finder peep window 14 by way of flip-flops FOVR, FUDR and the correct exposure controlling by the aperture-priority mode is accomplished in the state that the exposure set value is shifted and set newly at the threshold value. These become similar even with the aperture-priority mode, program mode and manual mode.
