ABSTRACT:
An automatic focusing camera having an indicator for producing an indication when the subject being photographed is too near the camera to be brought into focus. It also provides an inhibit signal if this situation exists thereby precluding operation of an exposure cycle. When the camera is operated in its flash mode, an indicator produces its indication if the subject is outside a predetermined range within which the shutter mechanism is capable of producing a properly exposed photograph under flash illumination and an inhibit signal is also provided in this situation to thereby preclude operation of an exposure cycle.
