<p>PURPOSE:To enable photographing to be performed at arbitrary aperture value or shutter speed by controlling exposure based on the shutter speed and aperture value determined by either of an exposure value varying means or exposure value determining means. CONSTITUTION:This is provided with a photometric circuit which generates the electric signal corresponding to the quantity of light from the subject, a film speed setting means, an EV value determining means, a program constant setting means, an exposure value determining means which determines shutter speed value and aperture value linearly in correspondence to outputting of the program constant setting means output and the EV value determining means output and an exposure value varying means which varies the relation between the shutter speed value and aperture value based on the output of the EV value determining means, to enable the combination of the calculated shutter speed and aperture value to be changed as desired by a control means which change said combination with the EV value being fixed.</p> |
