ABSTRACT:
In a photographic camera, a film speed setting member is manually movable to a plurality of film speed related positions corresponding to various speed films to be used in the camera. When a rear door of the camera is opened to load a selected speed film in the camera, the setting member is automatically moved to a non-film speed related position in which it at least partially blocks a window of the viewfinder in the camera. This serves to remind the photographer to move the setting member to the film speed related position corresponding to the speed of the loaded film before taking the first picture.
