ABSTRACT:
Flash and camera apparatus integrally incorporating an electronic flashing device for firing a flash discharge tube and a photographic camera device with a fixed focus lens system. The apparatus includes an aperture change-over mechanism for changing the aperture to an appropriate value depending on the paticular mode of photography selected. The selectable modes include both far and near modes for objects which are within allowable range of the camera to achieve proper flash mode photography and also daylight mode photography. An indication element for indicating the existence of a condition under which the electronic flash device is able to fire in the flash mode and which indicates whether the distance to the object is far or near is also provided. Further provided is a switch mechanism for simultaneously performing the functions of operating the aperture changeover mechanism, operating the indication element and supplying power to the electronic flash device. In this manner, daylight and flash mode photography are simplified, the allowable distance to the object for proper photography can be increased, and the distance from the object, i.e. far or near, is indicated for identification.
