the Canon EF 24-105mm f/4L IS lens that ships as part of the optional Canon 5D Mark II kit in the US has much better build quality than most kit lenses bundled with SLRs these days (such as the 18-55mm that shipped with the Canon Rebels), and has a longer zoom range as well. On a full-frame body like the 5D Mark II, it's wider than the 18-55mm, performed very well in our tests on SLRgear.com, and comes with image stabilization, a very worthwhile feature to have. This easy-to-use standard zoom lens can cover a large zoom area ranging from 24mm wide-angle to 105mm portrait-length telephoto, and its Image Stabilizer Technology steadies camera shake up to three stops. Constructed with one Super-UD glass element and three aspherical lenses, this lens minimizes chromatic aberration and distortion. The result is excellent picture quality, even at wide apertures. Canon's ring-type USM gives silent but quick AF, along with full-time manual focus. Moreover, with dust- and moisture-resistant construction, this is a durable yet sophisticated lens that meets the demands of advanced amateur photographers and professional photographers alike.
