Abstract:
An imaging apparatus comprises an optical system that includes a plurality of lens groups, each lens group including one or more lenses, at least one of the lens groups being independently movable with respect to the other lens groups and including a focus lens group for focusing the subject and a lens control unit that controls movement of the plurality of lens groups to bring into focus based on a feeding position of the focus lens group.
