A focusing glass and photographic system employing the same are disclosed. The photographic system includes an objective lens operable to form a real image of an object. The focusing glass is adapted to be situated at the real-image position, and comprises a semitransparent region surrounding a fully transmissive photographic zone. The photographic zone defines a region of the field of view of the objective (the field of view being viewable on the focusing screen) defining the metes and bounds of a photographic image obtainable using the photographic system.
