A zoom lens system for use in a compact camera with a lens shutter, having a zooming ratio about X2 and comprising a front lens group including a first lens group having a negative refraction power, a second and a third lens group, each having a positive refraction power, and a rear lens group including a fourth lens group having a negative refraction power. The front and rear lens groups are axially moved to change the distance therebetween and the second lens group is moved toward and away from the first lens group during the zooming operation. Numerical data are given for certain design features of the lens components which comprise the first to fourth lens groups, so that better correction of aberrations is attained.
