Abstract
An imaging apparatus on which a lens unit having a photographic optical system including a focus lens and capable of controlling driving of the photographic optical system based on information received from the imaging apparatus is mountable includes a filter driving unit configured to insert or retract an optical filter on an optical path of the photographic optical system, a detection unit configured to detect an insertion state of the optical filter, and a control unit configured to calculate, based on a change of the insertion state of the optical filter detected by the detection unit, a movement amount of an image forming position of an object image, and to transmit information on the movement amount of the image forming position of the object image and information indicating the insertion state of the optical filter to the lens unit.
