Abstract:
Comprising, in order from an object side: a first lens group G 1  having positive refractive power; a second lens group G 2  having negative refractive power; a third lens group G 3  having positive refractive power; a fourth lens group G 4 ; a fifth lens group G 5 ; and a sixth lens group G 6 ; upon zooming from a wide-angle end state to a telephoto end state, a distance between the first lens group G 1  and the second lens group G 2 , a distance between the second lens group G 2  and the third lens group G 3 , a distance between the third lens group G 3  and the fourth lens group G 4 , a distance between the fourth lens group G 4  and the fifth lens group G 5 , and the distance between the fifth lens group G 5  and a sixth lens group G 6  being varied; and a predetermined conditional expression being satisfied, thereby providing a variable magnification optical system which has a high variable magnification ratio, is compact in size and has high optical performance, an optical apparatus, and a method for manufacturing the variable magnification optical system.

Claim (Index 1):
A variable magnification optical system comprising, in order from an object side: a first lens group having positive refractive power; a second lens group having negative refractive power; a third lens group having positive refractive power; a fourth lens group; a fifth lens group; and a sixth lens group;\n upon zooming from a wide-angle end state to a telephoto end state, a distance between the first lens group and the second lens group, a distance between the second lens group and the third lens group, a distance between the third lens group and the fourth lens group, a distance between the fourth lens group and the fifth lens group, and a distance between the fifth lens group and the sixth lens group being varied; and the following conditional expressions being satisfied:\n 5.500< f 1/ fw< 10.200 \n 0.057<(\u2212 f 2)/ ft< 0.200 \n where fw denotes a focal length of the variable magnification optical system in the wide-angle end state, ft denotes a focal length of the variable magnification optical system in the telephoto end state, f1 denotes a focal length of the first lens group, and f2 denotes a focal length of the second lens group.
