To provide an imaging lens which constitutes a vibration insulation system in which both lens diameter and weight are small using a liquid lens for the imaging lens, with which successful optical performance is obtained even at a vibration insulation state and the whole apparatus is minimized and to provide an optical equipment using the same.

In the imaging lens having a plurality of lens groups to perform light guiding of an object image on the surface of a solid-state imaging device in a camera apparatus, it is constituted that a first lens group having negative focal distance, a second lens group having positive focal distance and a third lens group having positive focal distance are arranged in order from the object side, a diaphragm which integrally moves with the second lens group is provided on the object side of the second lens group and the liquid lens is equipped to a prescribed part in the second lens group as a movable lens which moves in the approximate perpendicular direction to a light axis of the imaging lens so as to compensate handshake when the handshake is generated at the time of photography.
