Abstract
A camera is provided with a data table memory which stores control data for controlling not only the position of a taking lens but also the aperture size of a program shutter. The data also determines whether a flash unit is to be actuated depending on the subject distance as well as the subject brightness, so that the depth of field and hence the focusable range can be enlarged by stopping down the aperture and using a flash light. The data table memory further stores flash timing data for controlling the timing of flashing of the flash unit.
