摘要： The image-pickup apparatus includes a controller that controls the energization of the actuator for driving the aperture stop. The controller receives from a lens apparatus information on a time period for controlling the energization of the actuator, the information being set corresponding to the type of the actuator. During an image-pickup period in a state in which the aperture stop has been driven to a target aperture position, the controller outputs to the lens apparatus an instruction for stopping the energization of the actuator or reducing the energization amount thereof in response to the elapse of the time period. This can reduce power consumption.

摘要： An optical apparatus is disclosed which can prevent displacement of subject images due to an initializing operation of the image stabilizing unit from being seen by a photographer through a finder. The apparatus comprises an image-stabilizing unit which includes a movable unit movable for image stabilization and balls movable in conjunction with the movement of the movable unit, and a controller which controls operations of the movable unit. The controller causes the movable unit to perform a specific operation for moving the balls to a specific position in response to mounting of the optical apparatus on another optical apparatus, the specific operation being a different operation from an image stabilization operation of the image-stabilizing unit.
