Disclosed is an autofocus device, particularly an autofocus device in which focus detection is effected repeatedly. A determination is made as to whether or not a determination of the in-focus state is made continuously for a predetermined duration upon repeated detection of focus after an initial in-focus determination is made. While the determinations of the in-focus state are being made for the predetermined duration after the initial determination on the in-focus state is made, the terminals of the motor are short-circuited to apply brakes to it, and after the aforementioned duration, the motor terminals are opened, thereby stopping the motor.
