Abstract: In a digital camera system comprising lens-barrels 12, 13 having an optical system including an objective 14, a finder 17, a monitoring liquid crystal display 18, a release button 19 and a controller 22 having a power supply, a ring flash 15 is provided on the lens-barrel so as to surround the objective, a metering sensor 26 is provided below the front end portion of the lens-barrel, and a light receiving surface 28 is inclined at an angle of 20 to 85 degrees with respect to the surface which is perpendicular to the optical axis of the optical system. Accordingly, the metering sensor reliably receives the reflected light from a subject, and the amount of light emission of the ring flash can be accurately controlled, so that it is possible to obtain clear images.
