PROBLEM TO BE SOLVED: To provide a camera capable of executing a precise focusing operation even in the state where the power voltage of a camera drops, prolonging the life of a battery to save resources, and preventing the missing of a shutter chance caused by a battery exchange operation, for instance. SOLUTION: This camera incorporates a range finder consisting of a light emitting/receiving device capable of executing three-point focusing and an AFIC 36 and a power source monitor 33 for checking the consumed state of a battery 41. At this time, in the state where the battery is not consumed yet, normal three-point focusing is executed, but the consumed state of the battery, the number of the points of multipoint focusing is limited to one, to suppress the consumption of power and increase the number of photographable films. |
