Abstract
A camera in which a T lens and a wide lens are respectively mounted on their respective lens holders which can be freely rotated and the T and W lenses are rotated to thereby switch over the T and w lenses to each other. The T and W lenses are supported such that they are freely rotatable. A CCD reference plate, on which a CCD can be mounted, is inserted over a lens support shaft and the mutual positional accuracy between the lenses and CCD can be enhanced through the lens support shaft. Also, the switching of the T and W lenses is executed in link with the movement of a plate cam, which is movable in a direction perpendicular to the lens support shaft for the T and W lenses, and a cam portion provided in the plate cam is used to move the T and W lenses in the axial direction of the lens support shaft to thereby adjust the focusing of the lenses. Further, an iris plate having a small diaphragm diameter is inserted into the optical axis of the T lens only in a macro photography to thereby increase the depth of field so as to allow the focusing in the macro photography.
