Abstract

A zoom lens includes, in order from an object side to an image side, a first lens group having positive refractive power, a second lens group having negative refractive power, a third lens group having negative refractive power, a fourth lens group having positive refractive power, a fifth lens group having positive refractive power, and a sixth lens group having positive refractive power. The zoom lens satisfies the following conditions: (1) 25<TT/fw<27; (2) 8.5 mm<BFL<12.5 mm; and (3) (V2+V5)−(V1+V6)>60. TT is a distance from the object side of the first lens group to the image side of the sixth lens group, fw is a shortest focal length of the zoom lens, BFL is a distance from the image side of the sixth lens group to the imaging sensor, and V1, V2, V5, V6 are Abbe numbers of the first, second, fifth, and sixth lens group, respectively.
