Abstract
A photographic camera comprising a principal objective lens assembly including an objective lens mount and a focus adjusting ring carried by the camera body through a fixed barrel for rotation through first and second predetermined focusing angle. The focus adjusting ring is operatively coupled to the objective lens mount such that rotation of the focus adjusting ring results in linear movement of the objective lens mount in an axial direction parallel to the optical axis of the objective lens. An optical converter lens is supported for movement between an inoperative position, in which the converter lens is out of alignment with the optical axis of the objective lens, and an operative position in which the converter lens is aligned with the optical axis of the objective lens. This optical converter is brought into the operative position when the focus adjusting ring is rotatable through the second focusing angle while it is brought into the inoperative position when the focus adjusting ring is rotatable through the first focusing angle.
