Abstract
A camera having a camera system which is capable of reducing the influence that vibration generated in conjunction with driving of an actuator has on other component members of the camera system. The camera includes a lens barrel having a fixed cylinder, a focusing lens group moving mechanism, an actuator, such as an ultrasonic motor, to supply a driving force to the lens group moving mechanism, a vibration detection device to detect vibration, and a camera vibration compensation mechanism to compensate for the detected vibration. The camera system includes a component member having multiple reinforcing sections and a characteristic frequency which does not overlap with a drive frequency band of the ultrasonic motor or with the vibration frequency band of the vibration generated in conjunction with the driving of the ultrasonic motor. The component member may be a stator retaining member which supports a stator of the ultrasonic motor, or a sensor fixed cylinder which secures the vibration detection device.
