Abstract

By the present invention it is possible to provide a variable magnification optical system an optical device having the optical system and a method for manufacturing a variable magnification optical system the variable magnification optical system being provided with optical performance whereby fluctuation in aberration during variation of magnification is reduced and it is possible to respond to fluctuation in aberration during camera shake correction by satisfying predetermined conditions by a configuration in which the variable magnification optical system has in order from the object a first lens group (G1) having a negative refractive power a second lens group (G2) having a positive refractive power a third lens group (G3) having a negative refractive power and a fourth lens group (G4) having a positive refractive power an interval between the first lens group (G1) and the second lens group (G2) changes an interval between the second lens group (G2) and the third lens group (G3) changes and an interval between the third lens group (G3) and the fourth lens group (G4) changes during variation of magnification from a wide angle end state to a telephoto end state and at least one single lens of the second lens group (G2) is an anti vibration lens group (VL) for moving so as to include a component in the direction orthogonal to the optical axis.
