Patent ID: 7068429

Claim:
A zoom optical system with a vibration correction function comprising, arranged along an optical axis in order from the object side as follows: a first lens group having positive refractive power and that is stationary during zooming; a second lens group having negative refractive power and that moves along the optical axis during zooming; a third lens group having positive refractive power that includes a stop and that is stationary during zooming; and a fourth lens group having positive refractive power that moves along the optical axis during zooming; wherein said first lens group includes, arranged along the optical axis in order from the object side, a lens element having negative refractive power, a prism for bending the optical axis, and at least one lens element having positive refractive power; and at least part of said third lens group is movable in a direction that intersects the optical axis in order to correct for blurring of an image due to vibration of the zoom optical system.
