Abstract
An optical device has an optical member that includes the optical device, an operating ring which can be rotated about the optical axis of the optical member and is used to drive the optical member, a switching mechanism which transmits the drive force from a motor drive source to the operating ring, and can be switched between a state for motor-driving the optical member and a state for canceling motor driving of the optical member, and control means for switching the switching mechanism between the motor-driving state and the motor-driving canceling state, and the control means switches the switching mechanism to the state for canceling motor driving on the basis of manual operation of the operating ring when the switching mechanism is motor-driving the optical member.
