摘要： A compact zoom lens of high magnification comprises four lens groups. In succession from the object side, the first lens group has a positive refractive power and a focusing function, the second lens group has a negative refractive power and a magnification changing function and consists, in succession from the object side, of a negative lens having its concave surface of sharper curvature facing the image side, a negative doublet lens consisting of a biconcave lens and a positive lens, and a negative lens having its concave surface of sharper curvature facing the object side, the third lens group has a positive refractive power and is reciprocable to correct the movement of the image point resulting from zooming, and the fourth lens group has a negative refractive power. Correction of aberrations is well accomplished by suitably selecting the focal length of the doublet lens in the second lens group and the curvature radii of the third, fourth and sixth lens surfaces in the second lens group as viewed from the object side.
