ZOOM LENS AND IMAGING APPARATUS

Abstract: the zoom lens consists of a first lens group, a front group, a middle group, and a rear group, in order from an object side. the first lens group has a positive refractive power and includes a negative lens and a positive lens, successively in order from a position closest to the object side to an image side. the front group consists of one or more lens groups that move during zooming and has a negative refractive power as a whole throughout an entire zoom range. the middle group includes only one lens group as a lens group. the rear group consists of a plurality of lens groups. an aperture stop is disposed between a lens surface closest to the image side in the front group and a lens surface closest to the object side in the rear group. the zoom lens satisfies predetermined conditional expressions.
