PURPOSE:To attain a change to an exposure mode with an easy operation by providing a means mutually/forcibly changing the exposure mode by the operation of an electronic dial. CONSTITUTION:Two automatic exposure modes of a normal program exposure mode and a hyperprogram exposure mode which can be changed to an exposure factor priority automatic exposure mode only by the operations of the electronic dials 17 and 19, are provided. When the hyperprogram exposure mode is selected, one of the electronic dials 17 and 19 is operated, so that the exposure mode is forcibly changed to one of the corresponding hypershutter speed and hyperdiaphragm priority exposure modes. Further, after this change, the other of the electronic dials 17 and 19 is rotationally operated, the exposure mode is forcibly changed to the other of the corresponding hyperdiaphragm and hypershutter speed priority automatic exposure modes. Moreover, when the exposure mode is forcibly changed, shutter speed or a, diaphragm value is changed by the rotational operations, of the electronic dials 17 and 19. |
