ABSTRACT:
The photographic camera has an optical direct viewfinder based on the inverse Galilean optical principle. The direct viewfinder is vertically extendible out of the camera body relative to the optical axis of the camera and is retractable back into the body. The direct viewfinder is designed as a one-piece U-shaped component enclosing the camera body and guided therein, with integrated front lens and integrated eyepiece lens. The extension movement is preferably effected by a compression spring exerting a corresponding force on the direct viewfinder.
