Abstract: PURPOSE:To realize the zoom lens which has high performance with a small number of lenses while suppressing deterioration in various aberrations by using >=2 aspherical surface for the 3rd lens group in the zoom lens consisting of three positive, negative, and positive elements. CONSTITUTION:The zoom lens consists of the 1st lens group LI with positive refracting power, the 2nd lens group LII with negative refracting power, and the 3rd lens group LIII with positive refracting power, and the air intervals of the groups LI - LIII are varied to vary the focal length of the whole system. Specially, >=2 aspherical surfaces are included in the 3rd lens group LIII and the conditions shown by inequalities I and II are satisfied. In the inequalities I and II, phi1 is the refracting power of the 1st lens group, phi3 is the refracting power of the 3rd lens group, and phiw is the refracting power of the whole system at the wide-angle end. Consequently, the compact, low-cost zoom lens in a 36 - 105 mm focal length class is obtained which consists of a small number of lenses while high optical performance is maintained.
