Abstract

A hybrid zoom lens system comprises a plurality of lens groups that provide optical zoom at specified increments, together with software enhancement between the optical increments to provide to the user the perception of continuous zoom. In an embodiment, at least one of the optical groups comprises two rotationally asymmetric, or free form, lenses where the optical zoom is effected by movement of the rotationally asymmetric lenses transverse to the optical axis. In some embodiments, software algorithms are applied to correct for distortion and aberration. In some embodiments, a at least one lens group of rotationally symmetric lenses is provided together with at least one lens group of rotationally asymmetric lenses, wherein the rotationally symmetric group cooperates with the rotationally asymmetric lens group to provide a change in optical power to assist with focusing, zoom, or both.
