Abstract

PURPOSE: To perform selective displaying of specified values readily and accurately by setting the camera which is program controlled according to the minimum aperture value of exchange lenses at the aperture priority mode when the set minimum aperture value is inadequate.
CONSTITUTION: When the minimum aperture value corresponding to the minimum aperture of exchange lenses is set by cooperating sliders W1, W3, a program shutter speed voltage is supplied from terminal T6 to the terminal 6a of a display circuit 6 and a comparator 4. On the other hand, the photometric voltage of a photometric circuit 1 is applied to the comparator 4 and the measurement voltage through the circuit 1 and a potentiometer PM1 is applied to the comparator 4, device 6, whereby the aperture is automatically controlled and at the same time the correct aperture value is displayed in the device 6. In case the set minimum aperture value is inadequate, a switch SW5 is connected to the contact O5 and the aperture priority mode is set, then the swtiches SW7, SW6 change over and the display of the device 6 is changed over to the shutter second time by the voltage corresponding to a reference shutter second time from the terminal T3 and the program shutter second time voltage from the potentiometer PM3.
