Abstract
A viewfinder device having an optical path for viewing a photographic image includes a plurality of visual field frames. Each of the plurality of visual field frames define a photographic range. In addition, each of the plurality of visual field frames is positioned on one of a plurality of visual field frame display units. The plurality of visual field frame display units have overlapping regions and are positioned on a viewfinder mask member. The viewfinder mask member is movable in the optical path. The overlapping portions of the visual field frame display units reduce an amount of movement necessary to move the viewfinder mask member to position the visual field frames within the optical path.
