    摘要: A zoom lens consists of, in order from an object, a first lens group having a negative refractive power, a second lens group having a positive refractive power, a third lens group having a negative refractive power, and a fourth lens group having a positive refractive power. Zooming is performed by changing respective distances between the first and second lens groups, the second and third lens groups, and the third and fourth lens groups. The first lens group consists of, in order from an object, a negative lens, a negative lens and a positive lens, the second lens group consists of five lenses, and the third lens group consists of a bi-concave negative lens.

    摘要: A first lens group having a negative refractive power, a second lens group having a positive refractive power, a third lens group having a negative refractive power, and a fourth lens group having a positive refractive power are provided in order from an object. The first to fourth lens groups move on an optical axis so that zooming is performed by changing each distance between adjacent lens groups. The first lens group comprises, in order from the object, a negative lens arranged closest to the object, a negative lens and a positive lens, and when an air interval between the third and fourth lens groups in the wide-angle end state is denoted as D3T and an air interval between the third and fourth lens groups in the telephoto end state is denoted as D3T, the following condition is satisfied: 0.30
