Title: ZOOM LENS, IMAGING DEVICE, MOBILE BODY, AND SYSTEM
Abstract:
Provided is a zoom lens comprising, in the stated order from the object side: a first negative lens group having a negative refractive power; a first positive lens group having a positive refractive power; and a second positive lens group having a positive refractive power. When changing magnification from a wide-angle end to a telephoto end, an interval from the first negative lens group to an imaging element is fixed, an interval between the first negative lens group and the first positive lens group decreases, and the second positive lens group moves in a convex arc trajectory toward the imaging element.
