Abstract
A first stop plate with a small stop opening is disposed behind a taking lens, and a second stop plate with a middle stop opening is disposed between a first and second lens, which comprise the taking lens. Upon moving a changeover knob to an ON position, a flash unit and the second stop plate are actuated such that the middle stop opening is retracted from an photographic light path PL. The small stop opening is retracted from the photographic light path PL when subject luminance is less than a predetermined value. In high-luminance condition, the small stop opening and the middle stop opening are set on the photographic light path PL, and in middle-luminance condition, the small stop opening is retracted. In low-luminance condition, the middle stop opening is retracted by operation of the changeover knob, so only a large stop opening is set on the photographic light path PL.
