Abstract

PURPOSE:To simultaneously observe two finder images within the same finder viewfield and with the same eyepiece, by setting a reflector at a part of the luminous flux of an optical finder system and leading an electronic finder image toward the eyepiece via the reflector. CONSTITUTION:The pickup surface 12a of an image pickup tube 12, i.e., an electronic finder image is set at a position 10B conjugate the secondary focusing surface 10A on which an optical finder image is formed. The electronic finder image is led toward an eyepiece 11A via a fully reflective mirror 13. In such way, both the optical and electronic finder images 15a and 15b can be observed simultaneously and within the same viewfield through the eyepiece 11A.
