ZOOM LENS AND OPTICAL EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a zoom lens capable of efficiently reducing chromatic abberation of magnification. SOLUTION: The zoom lens comprises, in order from the enlarging side, a first lens unit (L1) having a negative optical power, a second lens unit (L2) having a positive optical power, a third lens unit (L3) having a positive optical power, a fourth lens unit (L4) having a positive optical power, a fifth lens unit (L5), and a sixth lens unit (L6) having a positive optical power. When the focal length of the entire system at the wide-angle end is fw and the focal distance of the third lens unit is f3, the following condition is satisfied: 0
