IMAGING APPARATUS AND LENS BARREL

摘要

An imaging apparatus moves a lens in the optical axis direction with respect to the initialization position, and images a subject. The imaging apparatus includes a first lens, a second lens, a driving unit, a first position detection sensor, a second position detection sensor, a third position detection sensor, and a control unit. The driving unit moves the first lens and second lens in the optical axis direction. The first position detection sensor detects the position of the first lens. The second position detection sensor detects the position of the second lens. The third position detection sensor detects the position of the first lens and the position of the second lens. On the basis of the output from the third position detection sensor, the control unit executes the initializing processing of determining the initialization positions of the first lens and second lens.
