Abstract
The zoom lens is a lens system that forms an intermediate image, and includes, in order from the magnification side: a first lens group that remains stationary during zooming; a plurality of movable lens groups that move during zooming; and a final lens group that has a positive power and remains stationary during zooming. Two or more movable lens groups are positioned to be closer to the reduction side than the intermediate image. The lens system closer to the reduction side than the intermediate image includes, in order from the magnification side, a front group and a rear group. The zoom lens satisfies predetermined conditional expressions (1) and (2) relating to the rear group.
