Abstract

A parallax correcting mechanism for a camera having a zoom lens. An objective lens is placed in the optical path of a viewfinder and is movable perpendicular to the optical axis of the viewfinder in cooperation with the focusing mechanism of the associated camera. A movable lens is also placed in the optical path of the viewfinder and is movable along the optical axis of the viewfinder in cooperation with the zoom adjustment of a zoom lens associated with the camera. The movement of the objective lens corrects for any parallax error between the viewfinder and an image seen by the zoom lens of the camera. The movement of the movable lens insures that the field angle of the viewfinder will correspond to that of the zoom lens.
