    • A zoom lens includes: a first lens group having a positive refractive power and statically positioned along an optical axis when a power of the zoom lens is varied or the zoom lens is focused; a second lens group having a negative refractive power; a third lens group having a positive refractive power; a fourth lens group having a positive refractive power; a fifth lens group. The second and fourth lens groups are moved for varying the power of the zoom lens and the fourth lens group is further moved for focusing the zoom lens. The first lens group includes a reflective optical element for bending an optical path. The second lens group includes a cemented lens including a positive lens and a negative lens. The fourth lens group includes two positive lenses, and the fifth lens group includes one positive lens having at least one aspherical surface.
