Zoom lens and imaging apparatus using zoom lens

Abstract

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 lensincludes a first lens group Ghaving a positive refractive power, a second lens group Ghaving a negative refractive power, a third lens group Ghaving a positive refractive power, a fourth lens group Ghaving a positive refractive power, and a fifth lens group Ghaving 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 Gthe second lens group Gthe third lens group Gand the fourth lens group Galong an optical axis. Image stabilization for mitigating camera shake is performed by the movement of the fourth lens group Galong the direction perpendicular to the optical axis.
