ABSTRACT:
A camera or camera system includes a depth of field preview device for stopping down an aperture of an objective lens mounted on the camera to a predetermined aperture value in response to a manual operation prior to its photographing operation, and an AE lock device for storing a light measuring signal indicative of the brightness of object in response to another manual operation. In the camera or camera system, proper exposure can be obtained even if the depth of field preview device and the AE lock device are intended to be operated together, with compensating and correcting exposure error which would be produced by operation of both devices.
