Providing a zoom lens system having excellently correcting various aberrations with accomplishing to be compact, lightweight, and slim upon being retracted. The system is composed of, in order from an object, a first group having negative refractive power, and a second group having positive refractive power. Upon zooming from a wide-angle end state to a telephoto end state, a distance between the first group and the second group varies. The first group is composed of two lens elements which are, in order from the object, a negative lens having a concave surface facing an image, and a positive lens. The second group consists of three lens elements or less and includes, in order from the object, a positive lens, an aperture stop for defining an f-number, and a negative lens component including a negative lens and disposed to the image side of the aperture stop. Given conditions are satisfied.
