Abstract

PURPOSE: To make the zoom lens compact and to decrease aberrational variation by giving relatively low negative refracting power to a 5th lens element which is fixed at the time of power variation.
CONSTITUTION: A 1st lens element consists of one positive tablet composed of a negative meniscus lens and a biconvex lens and a positive meniscus lens which is convex to the object side in order from the object side and a 2nd lens element II consists of a negative lens which has a large-curvature surface on the image side and a negative tablet composed of a biconcave lens and a positive lens in order from the object side and a 3rd lens element III is one positive lens or a positive tablet composed of one positive lens and a negative meniscus lens; and a 4th lens element IV includes at least a negative lens having a large-curvature surface on the image side and one positive lens in order from the object side and the 5th lens V is composed of a single negative lens which has relatively weak refracting power. Consequently, the zoom lens is made compact, various aberrations are compensated excellently, and variation of the various aberrations due to power variation is reducible.
