Abstract
Providing a high optical performance zoom lens system with realizing a high zoom ratio and compactness suitable for a highly integrated electronic imaging device. The system includes, in order from an object along an optical axis: a first group Ghaving positive refractive power; a second group Ghaving negative refractive power; a third group Ghaving positive refractive power; a fourth group Ghaving positive refractive power; and a fifth group Ghaving negative refractive power. Upon zooming from a wide-angle end state W to a telephoto end state T, the second group Gand the fourth group Gare moved along the optical axis. The first group Gincludes, in order from the object along the optical axis, a front group Ghaving negative refractive power, an optical-path-bending element P for bending an optical path, and a rear group Ghaving positive refractive power. Given expression is satisfied.
