PROBLEM TO BE SOLVED: To obtain a zoom lens having a vibration compensating function capable of maintaining good optical performance over a whole variable power region in which the vibration compensation is performed in spite of the comparatively simple constitution. ;SOLUTION: This zoom lens is composed, in order from an object side, of a first lens group L1 having a negative refractive power, a second lens group L2 having a positive refractive power, a third lens group L3 having a positive refractive power and a fourth lens group L4 having a positive or a negative refractive power, power variation from a wide-angle end to a telescopic end is performed by moving the first, second and third lens groups on an optical axis, the fourth lens group L4 is a fixed zoom lens and the blurr of a photographied image when the zoom lens L4 is oscillated is compensated by moving the third lens group L3 in the direction almost perpendicular to the optical axis.;COPYRIGHT: (C)1999,JPO
