PURPOSE:To convert quickly and easily a set value by providing a shutter speed and diaphragm value display device in a finder, and also providing a shifting means for shifting a display value of one of them to a desired value in accordance with the indication of a direction indicating device in the finder. CONSTITUTION:A photographer can select easily the combination of a desired shutter second time and a diaphragm value by confirming visually a correct diaphragm value displayed in a finder and a shutter second time value displayed by a shutter display disk 354, after turning on a sub-power source switch SW1'. Subsequently, when the shutter button of a camera is pushed, first of all, a power source switch SW1 turns on, a power source controlling transistor E1 also turns on, an electric conduction is fed to a circuit. A luminance of an object to be photographed is made incident on a photodetector P.D. through a lens, and a logarithmically compressed value VBV0 (Bv0=Bv-Av0-Avc) of the luminance of the object to be photographed is outputted from a photometric circuit L. |
