At least one exemplary embodiment is directed to a zoom lens which
includes first to fourth lens groups, each moving and having negative,
positive, negative, and positive refractive power, arranged from an
object to an image in that order. The second lens group includes a second
A lens component composed of a single positive lens, and a second B lens
component composed of a negative lens and a positive lens with positive
refractive power as a whole, arranged from the object to the image in
that order. The second A lens component displaces images in a direction
substantially perpendicular to an optical axis by having a component of
it's displacement perpendicular to the optical axis, and the zoom lens
satisfies the following condition: 0.2
