Abstract
A camera having an electronic flash light apparatus capable of performing a phototaking with an optimal exposure both for an object and its background when a flash light phototaking is performed on the wide angle side of the camera with a backlight is provided with an electronic flash light apparatus for illuminating an object with ignition, driving means for varying the illuminating angles of the electronic flash light apparatus between the direction of the telescopic side and the direction of the wide angle side, driving means for moving a phototaking lens to the telescopic side and to the wide angle side, photometering means for photometering a principal object and the circumference of the main object respectively, luminance comparison means for comparing the luminance of the main object photometered by the photometering means and the luminance of the circumference of the main object, and control means for shifting the illuminating angle to the telescopic side by the electronic flash light apparatus driving means if the luminance comparison means determines the light to be a backlight when the phototaking lens is on the wide angle side.
