Abstract
Abstract A camera objective lens mount includes a first circular member rotatably mounted on the front of the camera focussing barrel parallel to the camera focal plane and has a first circular eccentric opening with a spherical peripheral face. A second circular member with a spherical peripheral surface mates and rotatably and tiltably engages the first opening and the camera objective lens is eccentrically mounted in and projects through the second member so as to be universally angularly adjustable and universally movable in directions parallel to the camera focal plane.
