ABSTRACT:
It is provided an imaging apparatus including a plurality of motors configured to be driven to move lenses in synchronous with a drive pulse, a position detection unit configured to detect one of positions of the lenses moved by the driving of the plurality of motors, an operation unit configured to perform an output corresponding to an operation in response to the operation by a user, and a controller configured to receive the output from the position detection unit and control the plurality of motors. The controller supplies the number of drive pulses calculated based on a target position for moving the lens calculated based on the output from the operation unit and a lens position detected by the position detection unit.
