ABSTRACT:
A camera includes a photographing optical system in which at least one of a plurality of reflecting surfaces is disposed between a plurality of lenses and the optical path is bent by two reflecting surfaces including the at least one reflecting surface so that an image of an object falls on a film surface substantially facing the object; and an observing optical system of real image type in which one of the two reflecting surfaces is configured as a movable or path splitting surface to conduct light outside the photographing optical system so that the image of the object can be observed. Thus, the height as well as the entire length of the camera is reduced and compact design of the camera can be attained.
