Abstract:
1. An image-taking apparatus comprising: an image-taking optical system which includes an offset lens unit being movable in a direction orthogonal to an optical axis of the image-taking optical system, the image-taking optical system being capable of variation of magnification; an image-pickup element which photoelectrically converts an image of an object formed by the image-taking optical system; and a memory which stores adjustment data, wherein the adjustment data is data on a movement amount of the offset lens unit to prevent substantially an object point image-formed at a center on the image-pickup element by the image-taking optical system from moving in a direction orthogonal to the optical axis during the variation of magnification, wherein the image-taking apparatus satisfies the following condition: where βi represents a paraxial lateral magnification of the offset lens unit, βr represents a paraxial lateral magnification of the lens system placed further on an image surface side than the offset lens unit of the image-taking optical system, and the βr is equal to 1 in a case of not having the lens system.
