1. A universal device for the relative displacement between the optical plane and the focal plane of a lens and a camera, characterized in that it is constituted from a frame (1) that fixes the body of the camera (2), from whose sides emerge forks (5) that end in respective joints (6) for a bridge (7-7′), with an inverted “U” shape, so that the imaginary axis that joins the two joints (6) coincides with the focal plane or sensor of the camera (2); and wherein the joints (6) include means for regulating the inclination of the bridge (7-7′) as well as a first guiding means (9) for the axial displacement of a pair of side arms (7′) of the bridge, a beam (7) of said bridge having a longitudinal second guiding means (11) for guiding a carriage (12) disposed between the longitudinal second guiding means (11) and a rotating base (14), whose axis of rotation coincides with the focal plane or sensor of the camera (2), the rotating base (14) in turn having a third guiding means (16) for a support (17) on which the lens (18) is fixed.
