PURPOSE:To enable displaying of whether set aperture value is proper or not to be made by comparing the operated information by a guide number and the output information corresponding to the set aperture value, and the distance information by an automatic distance measuring device. CONSTITUTION:A distance signal by the reflected light from an object is taken into a memory circuit 32 from a photodetecting circuit 31 including a photoelectric element and an amplifier circuit. Further, the distance signal having been stored into the memory circuit 32 is converted to digital signals a4-a1 by a distance signal converting circuit 33. These digital signals a4-a1 are compared with the digital signals b4-b1 of 4 bits corresponding to the photographable distance by conductor patterns 34-37 and sliding contact pieces 39-42, and warning displaying by a light emitting diode D1 or D2 is accomplished. |
