The optical apparatus includes a focus signal generator generating a focus signal from a photoelectrical conversion signal of an optical image formed by an optical system including a first lens unit for zooming and a second lens unit for focusing, a memory storing data indicating a relationship between positions of the first and second lens units, the data being generated for each predetermined in-focus distance. The controller moves the second lens unit in infinite and close directions. The controller changes a movement amount of a center position of the movement of the second lens unit in the infinite and close directions according to at least one selected from information on an operation of the optical system, information on a state of the optical system, and information on a photoelectric conversion operation of the optical image. |
