ABSTRACT:
Disclosed is a finder system for a camera. The finder system has real-image type first and second optical systems apart by a predetermined base length. Light passed through the first and second objective optical systems are combined and superimposed images are formed which is defined within a finder field. The second objective optical system is provided with a rotatable mirror which varies a direction of an optical axis of the second objective optical system with respect to the optical axis of the first objective optical system to vary degree of coincidence of the superimposed images. A rotation angle of the rotatable mirror is controlled based on information related to an object distance and a position within the finder field.
