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.
Claims21
-20. (canceled)
A method for introducing optical aberrations in a camera lens comprising passing an optical image through an attachment configured for attachment with the camera lens, wherein the attachment comprises one or more lens elements configured to produce the optical aberrations without any significant image compression in any axial direction.
The method of claim 1, wherein before the step of passing, the attachment is operatively coupled to the camera lens.
The method of claim 1, wherein the optical aberrations are selected from the group consisting of astigmatism, coma, flare, and combinations thereof.
An optical attachment for use with a camera, the optical attachment comprising a housing including a lens group therein comprising one or more lens elements, wherein the housing is configured to couple with a lens of the camera, wherein the lens group is configured to induce optical aberrations in the camera lens without significant image compression in any axial direction.
An optical attachment for use with a camera having a lens comprising a lens group of two or more lens elements disposed in an attachment housing, wherein the attachment housing is configured to connect with the camera lens, wherein the lens group is configured to produce optical aberrations for image capture by the camera, wherein any image compression produced by the optical attachment is less than 1.09.
