Abstract
An image capture apparatus includes: a zoom lens; and an image pickup device converting an optical image formed by the zoom lens into an electric signal. The zoom lens includes, in order from the object side, a first lens group with a negative focal length, a second lens group with a positive focal length, a third lens group with a negative focal length, and a fourth lens group with a positive focal length. During zooming from a wide-angle end to a telephoto end, the first lens group moves along a locus having a convex shape toward an image side while decreasing an air space between the first and second lens groups, and the second and third lens groups move toward the object side while increasing an air space therebetween.
