The invention makes a suitable selection from zoom modes and lens elements so thin that the thickness of each lens group can reduced, thereby slimming down a zoom lens with great thoroughness and, hence, an electronic image pickup system. The electronic image pickup system a zoom lens and an electronic image pickup device located on the image plane side of the zoom lens. The zoom lens comprises, in order from the object side, a first lens group G 1 comprising two lens components and having generally negative power and a second lens group G 2 comprising two lens components and having generally positive power. The focal length of the zoom lens can be varied by varying the air separation between the first lens group G 1 and the second lens group G 2 . The zoom lens should satisfy at least one of conditions (a) to (n).
