To overcome the following problem; when driving a lens by an oscillatory type motor, starting up the motor is delayed even if introducing a hybrid system AF, then, it takes a time to focus on a object.

In the second step drive control of the oscillatory type motor (driving a photographic optical system with fine resolution) by generating the traveling-wave oscillation of the oscillating body of the oscillatory type motor 15 based on the detection results by second focus detecting means 6 and 13 using a contrast detection system after performing the first step drive control of the oscillatory type motor (driving the photographic optical system with rough resolution) by generating the traveling-wave oscillation of the oscillating body of the oscillatory type motor 15 based on the detection result by a first focus detecting means 51 using a phase difference detecting system, an intermediate control of generating the standing-wave oscillation of the oscillating body before starting the second step drive control is performed after finishing the first step drive control.
