An optical device includes a shooting optical system including an AF lens, an AF lens driving apparatus for driving the AF lens, a detection unit for detecting a defocus amount corresponding to a difference between an image pickup position of an object and an imaging position of the object which is formed by the shooting optical system, and a control unit for drive-controlling the AF lens driving apparatus to reduce the defocus amount. The control unit detects a shooting magnification of the shooting optical system and changes a method of controlling the AF lens driving apparatus to reduce the defocus amount based on the shooting magnification. |
