ABSTRACT:
In a wide range focusing camera, a cooperating engagement members are provided in moveable parts of a focusing mechanism and an aperture opening selecting mechanism so as to force the latter into selecting a smaller one of the aperture opening areas when the focusing mechanism is actuated into moving the lens to the position suitable for a close range shot. At the same time, a strobe light is enabled. Thus, the focal depth can be increased, and a clear picture of a close range object can be taken without regard to the condition under which the object is placed in relation with the surrounding objects. Also, a three-dimensional object having a depth can be photographed at close range with a satisfactory result. Because a number of settings required for such close-up shots are instantaneously set either manually by hand or automatically by an auto-focusing mechanism, it is possible even for an inexperienced photographer to take clear pictures of objects at close range.
