Abstract

An optical instrument of the present invention has a first lens group and a second lens group capable of moving in an optical axis direction in order to perform optical zooming, and comprises a storage section for storing first position information relating to positions of the first lens group and positions of the second lens group corresponding to identical focal lengths that fall within a focal length region range in which zoom operations of the optical instrument are carried out, and second position information relating to positions of the first lens group and positions of the second lens group corresponding to different focal lengths that fall within the focal length region, and establishes a second optical state of a higher shooting magnification than a first optical state, when establishing substantially the same focal length as a focal length of the first optical state based on the first position information.
