Abstract:
A zoom lens consists of five lens groups including, in order from the object side, positive, negative, positive, positive, and positive lens groups. During magnification change, the first and fifth lens groups are fixed relative to the image plane, and the second, third, and fourth lens groups are moved to change distances therebetween. During magnification change from the wide-angle end to the telephoto end, the second lens group is moved from the object side toward the image plane side, and the fourth lens group is moved from the image plane side toward the object side. The fifth lens group includes at least two negative lenses, and satisfies the condition expression (1) below: 1.90
