An image capturing apparatus with an image sensor converting the image of a subject and an optical member in front of the image sensor. First and second piezoelectric elements at respective ends of the optical member are independently driven by respective first and second driving units. A detection unit has first and second detecting piezoelectric elements adjacent to the respective first and second piezoelectric elements for detecting vibration of the optical member. A first control unit controls the first and second driving units and the detection unit to vibrate the optical member by vibrating the first piezoelectric element and detect vibration of the optical member using the second detecting piezoelectric element, or vibrate the optical member by vibrating the second piezoelectric element and detect vibration of the optical member using the first detecting piezoelectric element.
