Abstract
An objective lens for a still or film camera includes a first and second lens-element arrangement, and a wavefront manipulator. The first and second lens-element arrangement are spaced mutually apart along an optical axis of the lens such that an interstice is present therebetween. The wavefront manipulator is in the interstice and includes two optical components displaceable counter to one another, perpendicular to the optical axis, and which each include a free-form surface. The wavefront manipulator has a zero position, wherein the optical components do not cause any image aberrations in the imaging properties of the objective lens, and effective positions, wherein the optical components are displaced counter to one another, out of the zero position perpendicular to the optical axis, and wherein the optical components cause a spherical aberration in the imaging properties of the objective lens.
