ABSTRACT:
A camera which incorporates a supplemental lens that may be selectively used in combination with a normal picture-taking lens by moving a selector device projecting externally of the camera. Movement of the selector device results in the supplemental lens being moved either into or out of the optical path of the picture-taking lens. An objective lens which is positioned in the optical path of the view finder system is operable so as to be movable with respect to the view finder optical path upon movement of the supplemental lens to automatically compensate for parallax when the supplemental lens is positioned in the optical path of the picture-taking lens for modified photography.
