Abstract
Provided is an interchangeable lens including: a lens position detection unit configured to detect a position of a lens; a motor configured to move a movable lens frame to which the lens is fixed; a driving state detection unit configured to detect a driving state of the motor; and a control unit configured to decide a driving speed of the motor based on a difference between a target speed, which is based on a difference between a target position of the lens acquired from an imaging device and the position of the lens detected by the lens position detection unit, and a speed according to the driving state detected by the driving state detection unit.
