Abstract:
1. An optical apparatus comprising: a base member; a holding member which holds a first optical member, and is arranged so as to be movable in a direction perpendicular to an optical axis with respect to the base member; a diaphragm base member which holds a diaphragm blade, and is arranged so as to be movable in a direction perpendicular to the optical axis with respect to the base member; a first driver which drives the holding member in the direction perpendicular to the optical axis; a second driver which drives the diaphragm base member in the direction perpendicular to the optical axis; a vibration detector which detects vibration of the optical apparatus; and a controller which controls the first driver and the second driver in accordance with an output of the vibration detector, wherein the controller drives the second driver in a direction which is the same as the driving direction of the first driver.
