To provide a zoom lens which attains high zoom ratio and high optical performance over the entire zoom range, enables vibration control and miniaturization, and is compatible with a solid-state imaging device with a large size and a large number of pixels, the zoom lens 10 includes a first lens group G 1 having a positive refractive power, a second lens group G 2 having a negative refractive power, a third lens group G 3 having a positive refractive power, a fourth lens group G 4 having a positive refractive power, and a fifth lens group G 5 having a positive refractive power, which are sequentially arranged in that order from the object side. Zooming is performed by the independent movement of the first lens group G 1, the second lens group G 2, the third lens group G 3, and the fourth lens group G 4 along an optical axis. Image stabilization for mitigating camera shake is performed by the movement of the fourth lens group G 4 along the direction perpendicular to the optical axis.
