Abstract:
The zoom lens ( 1 ) includes an aperture stop (ST 1 ), at least three front side movable lens units (B 2  to B 4 ) disposed on an enlargement conjugate side further than the aperture stop and movable for zooming, and a front side fixed lens unit (B 1 ) disposed on the enlargement conjugate side further than the at least three front side movable lens units and fixed for the zooming. The at least three front side movable lens units include two first front side movable lens units (B 2  and B 3 ) movable to the enlargement conjugate side for zooming from a wide-angle end to a telephoto end, and a second front side movable lens unit (B 4 ) disposed on the reduction conjugate side further than the first front side movable lens units and movable to the reduction conjugate side for the zooming from the wide-angle end to the telephoto end.

Claim (Index 1):
A zoom lens comprising:\n a stop; at least three front side movable lens units that are disposed on an enlargement conjugate side further than the stop and that are movable for variation of magnification; and\n a front side fixed lens unit that is disposed on the enlargement conjugate side further than the at least three front side movable lens units and that is fixed for the variation of magnification, wherein the at least three front side movable lens units include: \n two movable lens units as first front side movable lens units that are movable to the enlargement conjugate side for variation of magnification from a wide-angle end to a telephoto end; and \n one movable lens unit as a second front side movable lens unit that is disposed on the reduction conjugate side further than the first front side movable lens units and that is movable to the reduction conjugate side for the variation of magnification from the wide-angle end to the telephoto end.
