Abstract:
1. A zoom lens comprising, as arranged sequentially from an object side: a first lens group having a positive refractive power; a second lens group having a negative refractive power; a third lens group having a positive refractive power; a fourth lens group having a positive refractive power; and a fifth lens group having a positive refractive power, wherein at least four lens groups including the first lens group, the second lens group, the third lens group, and the fourth lens group independently move along an optical axis to implement zooming, at least part of a lens group of the fourth lens group moves along a direction perpendicular to the optical axis to displace an image; and the zoom lens has a zooming range in which a space between the third lens group and the fourth lens group is gradually reduced from a wide angle end to a telephoto end.
