ABSTRACT:
Providing a zoom lens system that can excellently correct aberrations over entire range from a wide-angle end state W to a telephoto end state T in spite of having a high zoom ratio including, in order from an object, a first group G1having positive power, a second group G2having negative power, a third group G3having positive power, a fourth group G4having negative power, and a fifth group G5having positive power. When zooming from the wide-angle end state W to the telephoto end state T, a distance between the first group G1and the second group G2increases, a distance between the second group G2and the third group G3decreases, a distance between the third group G3and the fourth group G4increases, and a distance between the fourth group G4and the fifth group G5decreases. Given conditions are satisfied.
