Abstract
An image pickup apparatus on which an interchangeable lens is removably mounted, includes an image pickup element configured to perform a photoelectric conversion of an optical image formed via the interchangeable lens, and a controller configured to control a power supply to the interchangeable lens mounted on the image pickup apparatus. When the mounted interchangeable lens is a first type interchangeable lens and a power is turned off, the controller performs an aperture control so as to change a first aperture state set in the interchangeable lens to a second aperture state and then stops the power supply to the interchangeable lens. When the mounted interchangeable lens is a second type interchangeable lens and the power is turned off, the controller maintains the power supply differently from a case where the mounted interchangeable lens is the first type interchangeable lens.
