The build quality of the Canon lens is slightly better compared to the typical low-end/"budget" class zoom lenses by Canon. The plastic quality is quite decent and the lens feels pretty "tight" in terms of build tolerances. The mount is made of metal.

Mid-way between a standard kit lens and a do-it-all superzoom, the Canon EF-S 18-135mm f/3.5-5.6 IS USM offers a good zoom range, decent optical performance and super-fast autofocus.
