摘要
PURPOSE: A zoom lens system and a photographing apparatus including the same are provided to optimize the space of the zoom lens system by bending an optical path using an optical unit.;CONSTITUTION: A first lens group(G1) includes positive refractive power. The first lens group includes a first lens(1), optical units(2, 3) changing the optical path of light transmitted through the first lens, and a second lens(4). A second lens group(G2) includes negative refractive power. The second lens group includes a third lens(5), a fourth lens(6), and a fifth lens(7). The third lens group(G3) includes positive refractive power. The third lens group includes two or three lenses. A fourth lens group(G4) includes positive refractive power. The fourth lens group includes a ninth lens(11) and a tenth lens(12). The second lens group and the fourth lens group are moved in a zooming process. The first lens group and the third lens group are fixed in the zooming process.;COPYRIGHT KIPO 2011
