ABSTRACT:
A real image viewfinder includes an objective lens, a variator, an image reflecting optic unit, and an eyepiece lens that define a first optical path in which a first real image plane is located between the objective lens and the eyepiece lens, and can be viewed through the eyepiece lens. The reflecting optic unit is movable to compensate for variations in the position of the first real image focal plane such that the real image focal plane moves simultaneously with movement of the reflecting optic unit and also is adapted to define a second optical path through the viewfinder such that a second real image plane is located at the focal plane of the eyepiece lens, where an information display can be located.
