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 G1 having positive power, a second group G2 having negative power, a third group G3 having positive power, a fourth group G4 having negative power, and a fifth group G5 having positive power. When zooming from the wide-angle end state W to the telephoto end state T, a distance between the first group G1 and the second group G2 increases, a distance between the second group G2 and the third group G3 decreases, a distance between the third group G3 and the fourth group G4 increases, and a distance between the fourth group G4 and the fifth group G5 decreases. Given conditions are satisfied.
