ABSTRACT:
A shake-preventing correction optical system has in order from the object side a lens unit (Gf) fixed in a direction perpendicular to the optical axis and a shake-preventing correction lens unit (Gv) including a decentering lens unit arranged as movable in a direction substantially perpendicular to the optical axis, wherein the lens unit (Gf) has a first lens unit (G1) having a positive refractive power, a focusing lens unit (G2) having a negative refractive power and arranged to move along the optical axis to effect focusing to a near object, and a lens unit (G3a), and wherein the shake-preventing lens unit (Gv) includes the decentering lens unit (G3b) having a positive lens and a negative lens. The shake-preventing correction optical system has the decentering lens unit composed of a small number of constituent lens or lenses and has good imaging performance even upon shake-preventing correction.
