An image stabilization apparatus comprises: a first optical correction unit; a second optical correction unit that is arranged at a position different from the first optical correction unit in an optical axis direction of the first optical correction unit; and a control unit configured to execute a first control mode in which camera shake is optically corrected by shifting the first optical correction unit in a direction that is different from an optical axis based on a camera shake correction signal calculated from output from a camera shake detection unit, and in which the second optical correction unit is shifted in a direction different from the optical axis to correct aberration that occurs due to shifting the first optical correction unit in a direction different from the optical axis.
