ZOOM LENS AND IMAGING APPARATUS

摘要

A zoom lens is constituted by, in order from the object side to the image side: a positive first lens group; a positive second lens group; a negative third lens group; a negative fourth lens group; and a positive fifth lens group. The first lens group and the fifth lens group are fixed with respect to an image formation plane while the second lens group, the third lens group, and the fourth lens group move to change the distances among adjacent lens group when changing magnification. Conditional Formula (1) below is satisfied.;2.1
