Zusammenfassung:A zoom lens and a photographing apparatus having the same. The zoom lens includes a first lens group having a positive refractive power, a second lens group having a negative refractive power, a third lens group having a positive refractive power, and a fourth lens group having a positive refractive power that are sequentially arranged from an object side to an image plane side. An interval between the lens groups adjacent to each other varies when the zoom lens zooms from a wide angle position to a telephoto position. The zoom lens satisfies the following inequality: 1.8
