Abstract
A compact folding camera having a mirror in its exposure optical path includes a self-erecting and folding viewfinder. Major camera components include a base housing section having a film plane therein, a pivoting lens housing near one end of the film plane mounting an objective lens and front viewfinder lens, a pivoting mirror assembly near the opposite end of the film plane, a foldable bellows, a cover section, and a rear viewfinder lens mounted on the trailing end of the base section for movement between erected and storage positions. When the camera is erected, the rear lens assumes its upstanding erected position in optical alignment with the front lens for forming a direct viewing viewfinder. As the camera is folded, the lens housing folds back down over the base section so as to overlie the film plane and movement of the cover section toward its storage position overlying the base section causes viewfinder erecting structure to pivot the rear viewfinder downwardly to its storage position.
