The zoom lens system and camera using the same include, in order from an object side, a first lens group having negative refracting power and a second lens group having positive refracting power. Zooming is carried out at least by changing the distance between the first and second groups. The first lens group includes six lenses, a first lens which is negative meniscus lens having a concave surface toward an image side, a second lens which is negative meniscus lens having a concave surface toward the image side, a third lens which is negative lens having a concave surface toward the image side, a fourth lens which is positive lens having convex surfaces, a fifth lens having negative power and a sixth lens having positive power. The second lens group includes six lenses and the following condition is satisfied. 0.07<d12/f2G<0.30 where d12 is an air space on an optical axis between the first lens and the second lens in the second lens group, and f2G is a focal length of the second lens group.
