Abstract
A control apparatus for use with an optical apparatus includes an acquiring unit configured to acquire focus information from the optical apparatus, and a control unit configured to control, according to the focus information, movements of a first focus lens and an element that are independently movable in an optical axis direction. The control unit performs first driving that moves the element so as to reduce an image-plane moving amount caused by a movement of the first focus lens in simultaneously moving the first focus lens and the element.
