ABSTRACT:
This invention provides a camera of a simple structure installed with an electronic flash. The shutter speed is fixed and the opening of an iris diaphragm alone is variable. Values of the iris diaphragm opening are indicated by pictures so that an appropriate value can easily be selected. Pictures include two kinds, namely pictures of weather marks indicating the weather condition and pictures of distance marks indicating the distance to an object to be photographed. These picture marks are interchanged by "on" and "off" operations of a switch of a power source of the installed electronic flash. More specifically, when the switch is put off, weather marks alone can be seen, and when the switch is put on, distance marks alone can be seen.
