A viewfinder device is arranged to have a pair of light deflecting members disposed in front and in rear of an objective lens, to drive the front light deflecting member to guide light of a left side area of a field of view and light of a right side area of the field of view alternately to the objective lens, and to drive the rear light deflecting member to guide light fluxes thus obtained from the objective lens alternately to the eye of a person taking a sight of the field of view. This arrangement enables the viewfinder device to make a wide range of field sightable and yet permits a reduction in size of the objective lens.
