Abstract

A variable-exposure-size camera has an aperture member which defines an aperture through which a photographic film positioned behind the aperture member is exposed to light passing through a taking lens, and a pair of mask members which are disposed between the aperture member and the taking lens and are moved up and down toward and away from each other to change the effective upper and lower edges of the aperture, thereby narrowing the effective opening area of the aperture. The lower edge portion of the upper mask member and the upper edge portion of the lower mask member are bent toward the film surface so that the extreme edges of the edge portions which respectively define the upper and lower edges of the effective opening area of the aperture are positioned near the film surface.
