Lens for a photo or film camera and method for selectively attenuating certain spatial frequency ranges of the modulation transfer function of such a lens

There is provided a lens for a camera or film camera. The lens includes a first lens array (1), at least a second lens array (3) and at least one wave front manipulator (5). The first lens array (1) and the second lens array (3) (OA) of the lens along an optical axis spaced apart, so that between the first lens array (1) and the second lens array (3) an intermediate space (9) is present , The wavefront manipulator (5) is located in the intermediate space (9) between the first lens array (1) and the second lens array (3). It comprises at least two optical components (19, 21) perpendicular to each other in opposite directions to the optical axis (OA) of the objective are arranged displaceably and in each case at least one free-form surface (23, 25). The wavefront manipulator (5) has a zero position on where its optical components (19, 21) do not cause aberrations in the imaging properties of the lens, and operative positions in which the optical components (19, 21) in opposite directions perpendicular to the optical axis (OA ) of the objective lens from the zero position are displaced and in which the optical components (19, 21) comprises at least a spherical aberration in the imaging properties of the objective cause.
