A zoom lens includes, in order from the object side, the first lens unit consisting of one negative lens component in which a plurality of lens components are cemented to one another and the second lens unit including one negative lens component and having positive refracting power as a whole. In this case, the zoom lens satisfies the following condition: <?in-line-formulae description="In-line Formulae" end="lead"?>0.15<t<SUB>1</SUB>/fw<0.6<?in-line-formulae description="In-line Formulae" end="tail"?> where t<SUB>1 </SUB>is the thickness, measured along the optical axis, of the first lens unit and fw is the focal length of the entire system at the wide-angle position of the zoom lens.
