Variable magnification optical system and image-taking apparatus |
摘要 |
A variable magnification optical system includes: a plurality of lens groups for imaging a ray from the object side onto the light-receiving surface of an image sensor; and an optical prism for deflecting the optical path of the ray guided by these lens groups. The variable magnification optical system further includes an anamorphic lens element, which alters a beam of rays so that the beam becomes nonaxisymmetric to the optical axis.
