Abstract

An imaging apparatus includes: an imaging optical system having a variable power lens and a focus lens; an imaging element that generates image data via the imaging optical system; a movable frame that holds the focus lens and is movable along an optical axis of the imaging optical system; a first driving unit that causes the movable frame to move toward an in-focus position along the optical axis direction; a focus sensitivity determination unit that, based on a zoom position of the variable power lens, determines whether a focus sensitivity indicating a ratio of a change amount of the in-focus position to a movement amount of the focus lens is equal to or smaller than a specified value; and a driving controller that drives the first driving unit to move the movable frame to the in-focus position if the focus sensitivity is larger than the specified value.
