ABSTRACT:
An electronic control camera in which, when an electronic flash is used with the camera, the required exposure data is automatically set. In the electronic control camera to which the invention pertains, film sensitivity data and luminance data provided by a photometric unit are applied to a data processing unit, which utilizes those tow data values to control the shutter speed and/or the aperture value. Further, the data processing unit varies the shutter speed, the aperture value and/or the amount of light emitted by the electronic flash coupled to the camera in accordance with these two data values.
