PROBLEM TO BE SOLVED: To eliminate the need of an operation means selecting one of a shutter speed and a stop value by detecting rotational manipulated variable as the shutter speed by rotating a dial in one direction and detecting the rotational manipulated variable as the stop value by rotating the dial in the other direction in a manual exposure mode. SOLUTION: In a shutter speed priority mode, the shutter speed is set by adding a shutter speed information value T by the counterclockwise rotation of the dial 3 and subtracting it by the clockwise rotation of the dial 3. In a stop value priority mode, the stop value is set by adding stop value information F by the counterclockwise rotation of the dial 3 and subtracting it by the clockwise rotation of the dial 3. In a manual mode, the setting of the shutter speed is changed by rotating the dial 3 clockwise and the setting of the stop value is changed by rotating the dial 3 counterclockwise based on difference between the rotating directions of the dial 3 when the dial 3 is operated to be rotated. Each setting of the shutter speed and the stop value is changed by adding the respective values by rotating the dial 3. Then, a loop-like set pattern returned to T=1 from T=11 is formed in the case of the shutter speed. The loop-like set pattern returned to F=1 from F=10 is formed in the case of the stop value. |
