ABSTRACT:
In an automatic exposure control camera in which exposure is controlled based on an output of an arithmetic unit, the F-value information of the taking lens of the camera in the arithmetic unit is compensated by use of a distance information from a distance detector, and the exposure is controlled based on the compensated F-value, whereby the exposure is compensated in close-up photography.
