Abstract
Apparatuses, systems, and methods for producing non-rotationally symmetric optical aberrations. Such aberrations may be created by a removable attachment that may be attached to another lens, such as a spherical lens. Aberrations that appear to reproduce an anamorphic effect may be produced, yet the underlying camera system may remain a spherical camera system, and the capture mode may remain non-anamorphic.
Claims20
An attachment for use with a camera system, wherein the attachment comprises a lens group including lens elements, the lens group being configured to induce non-rotationally symmetric optical aberrations in a lens of the camera system without producing compression in any axial direction of greater than 1.09, and wherein the lens group is configured to be positioned between an object space and the camera lens.
A camera lens system comprising:
- a camera comprising a lens;
- and
- a removable attachment including:
- a lens group including at least two lens elements, the lens group being configured to induce non-rotationally symmetric optical aberrations in the camera lens without producing compression in any axial direction of greater than 1.09;
- and
- a housing coupled to the lens group and configured to removably attach to the camera lens with the lens group interposed between an object space and the camera lens.
A method for inducing an optical effect in a lens comprising:
- providing an attachment that includes a lens group connected with a housing, the lens group comprising lens elements, wherein the housing is configured to attach to a lens such that the lens group is positioned between an object space and the lens;
- and
- inducing, with the lens group, a non-rotationally symmetric aberration in the lens without producing compression in any axial direction of greater than 1.09.
