An optical equipment comprises: a first lens for focusing and compensation for magnification variation; a second lens for magnification variation; position detection means for detecting positions of the first lens and the second lens; focus detection means for detecting a focus status; lens drive means for driving the first lens and the second lens; and control means for controlling the lens drive means in accordance with information from the position detection means and the focus detection means. The control means determines a drive range of the first lens in which a circle of confusion may be zero, in accordance with focal length information, and inhibits the first lens from being driven out of the range during the magnification variation of the second lens.
