A zoom lens formed of a plurality of lens groups and performing zooming by changing separations between predetermined lens groups. A lens group closest to an object side is fixed in both optical axis directions during zooming, and has a reflecting member for folding an optical axis approximately 90 degrees. A final lens group positioned closest to an image side and fixed in both optical axis directions during zooming has a lens part group SG having positive refractive power and a lens part group RG arranged adjacent to the image side of the lens part group SG and having negative refractive power. A blur is corrected by shifting the lens part group SG in either direction perpendicular to the optical axis.
