摘要： According to one aspect of the present invention, a zoom lens system includes, in order from an object along an optical axis, a first lens group having negative refractive power, and a second lens group having positive refractive power. A distance between the first lens group and the second lens group decreases when the state of lens group positions varies from a wide-angle end state to a telephoto end state. The second lens group is composed of, in order from the object, a first lens having positive refractive power, a first cemented lens having negative refractive power, and a second cemented lens having positive refractive power. The first cemented lens in the second lens group is constructed by a positive lens cemented with a negative lens. The second cemented lens in the second lens group is constructed by a negative lens cemented with a positive lens.
