PROBLEM TO BE SOLVED: To provide a super compact zoom lens having the angle of view of about 2ω=74.1 deg. to 11.8 deg., having a variable power ratio of about 6.6, made small in diameter and small in size to a possible limit, constituted of small number of lenses, made excellent in cost performance and realizing high performance and high magnification. SOLUTION: This zoom lens has a 1st lens group G1 having positive refractive power, a 2nd lens group G2 having negative refractive power, at least one lens group and a lens group Gm having positive refractive power in this order from an object side, and power is varied by changing a distance between the 1st and the 2nd lens groups G1 and G2. Then, the lens group Gm is constituted of a positive lens component L1 whose convex surface faces to an image side and a negative lens component L2 whose concave surface faces to the object side in this order from the object side, and satisfies a specified condition.
