ABSTRACT:
A view finder is disclosed which uses an optical or frame-type view finder and an electronic view finder in combination. In the view finder, the image forming surface of the optical or frame-type view finder and the picture image surface of the electronic view finder are maintained in an optically equal distance relationship with respect to an eyepiece, so that both an optical image incident onto the optical or frame-type view finder and a display image displayed by the electronic view finder can be guided to the eyepiece through a half mirror. For this reason, either of the optical image incident onto the optical or frame-type view finder or the display image displayed by the electronic view finder can be viewed selectively, and also both images can be viewed in a hybrid state.
