The optical apparatus including a motor to move an optical element, a position detector configured to detect a position of the optical element, a controller configured to control drive of the motor by using a position detection signal from the position detector, and a memory configured to store a reference movement amount of the optical element corresponding to a moving speed and a moving time period of the optical element moved by the motor. The controller is configured to acquire a correction value for reducing a difference between (a) an actual movement amount of the optical element obtained by using the position detection signal when the optical element is moved by the motor and (b) the reference movement amount, and then to control the drive of the motor by using the correction value.
