Abstract: A zoom lens includes, in order from an object side to an image side: a first lens group that has a positive refractive power; a second lens group that has a negative refractive power; a third lens group that has a positive refractive power; and a fourth lens group that has a positive refractive power. During zooming from a wide-angle end to a telephoto end, the first lens group is stationary relative to an imaging surface, and the second lens group is moved to the image side in an optical axis direction so as to decrease a space between the second lens group and the third lens group. The third lens group includes a positive lens, a negative lens, and a cemented lens. The zoom lens satisfies ?0.95<fg3_neg/fg3<?0.5. Here, fg3_neg is a focal length of the negative lens of the third lens group, and fg3 is a focal length of the third lens group.
