ABSTRACT:
A zoom lens camera equipped with a flash unit including a flash unit and zoom lens. The illuminating angle of the flash unit varies with a change in the magnification of the zoom lens so as to effectively direct the flash light of the flash unit to an object to be photographed. Further, when the flash unit includes a light sensor sensing the light reflected from the object, the sensing angle of the light sensor also varies with a change in the magnification of the zoom lens so as to effectively control the quantity of the flash light directed to an object to be photographed.
