Abstract
A lens barrel includes a detecting unit that detects a position of an optical element in an optical axis direction, a driving unit that drives so as to change the position of the optical element in the optical axis direction, and a memory that stores setting information about the position of the optical element in the optical axis direction. The lens barrel is switchable between a storage mode for storing setting information about a first position of the optical element in the memory, and a reproduction mode in which the driving unit transfers the position of the optical element to the first position. Setting information about a position of the optical element is repeatedly storable in the memory in the storage mode. Setting information about a position of the optical element is prohibited from being stored in the memory in the reproduction mode.
