Claim:
1. An imaging apparatus comprising: a focus lens; a motor for driving the focus lens; an origin detection unit for detecting an arrival of the focus lens at a reference position; a drive amount detection unit for detecting an amount of drive of the focus lens driven by the motor; and a controller for recognizing a position of the focus lens based on an output from the drive amount detection unit, and for controlling the position of the focus lens, wherein the controller: (i) determines the occurrence of the step-out of the motor when a difference between the position of the focus lens detected by the origin detection unit and the position of the focus lens recognized by the controller is out of a predetermined range, and (ii) only when the occurrence of the step-out of the motor is determined, sets the position of the focus lens recognized by the controller to the reference position.
