ABSTRACT:
The observation device includes: an optical unit on which an intermediate image of an object to be observed is formed; a display unit that displays an image of a subject to be photographed; and a display unit moving unit that causes the display unit to be inserted in and removed from an optical light path for observing the object without moving the optical unit. Also, the camera includes: a finder optical system and an image-capturing unit that captures an image of a subject. The finder optical system includes an eyepiece unit; a focal plane plate on which an intermediate image of an image of a photographic subject is formed; a display unit that emits light; and a display unit moving unit that causes the display unit to be inserted in and removed from a light path in a position closer to the eyepiece unit than the focal plane plate.
