Abstract: An optical system including: a first movement group moving along an optical axis direction at the time of focusing from an object at infinity to a short-distance object; and a second movement group provided on an image side of the first movement group and moving to an object side by an amount of movement different from an amount of movement of the first movement group at the time of focusing from the object at infinity to the short-distance object. The optical system further includes an image stabilization group.
