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.

Announced at the beginning of September, this new Canon standard zoom lens was designed to complement the EOS 7D body on which we tested it. Providing a focal length range equivalent to 29-216mm in 35mm format, the EF-S 18-135mm f/3.5-5.6 IS covers both wide enough angles for landscape photography...

The Canon EF-S 18-135mm f/3.5-5.6 IS Lens is designed as a step up from the standard-at-review-time 18-55mm IS kit lens. The 18-135's most attractive features are a wide (7.5x) focal length range , a low price , a relatively light weight/small package, and a very nice IS (Image Stabilization)...

The Canon EF-S 18-135/3.5-5.6 IS is a wide to telephoto zoom and gives the same angle of view range as a 28-216mm lens would on a full frame 35mm camera. This range covers a lot of applications from landscapes at the 18mm wide end, through portrait shots in the 50-80mm range and on to sports and...

Bundled often as a kit with the Canon EOS 7D and 50D, this APS-C format zoom ($450, street) is for shooters who want more than a bare-bones 18–55mm kit lens without paying $575 (street) for the extra reach of Canon's 18–200mm IS superzoom.

My experience with Canon's lenses over the past 15 years have been nothing but excellence. And, they keep on improving their lenses, as well.

Light; Image Stabilizer(off or on); quick and responsive; FAST! Wide and Zoom

A great EF-S APS sized zoom lens that covers a mild wide angle to telephoto range. The 4 stops IS marketing fluff is true. It tested it down to 1/4 of a second and the images come out crisp and clean as against IS being turned off where camera shake and blur really shows.

A wonderful image range of 18-135mm (29-216mm), REAL Image Stabilization rated at 4 stops; 3 stops rating on other reviews, but hey, 3 to 4 stops is great feature, The difference between a non IS and IS on a 70-200mm white lens is over a thousand dollars.

It looks like a plain cheap cylinder, not a sexy lusty lens; It doesn't demand attention as the more sexy L and white lenses, Soft at the wide angle end, for the pixel conscious; Set to F8 and sharpness improves dramatically

Bad lens.

erratic AF; awful CA; really short sharpening

good use range; good color; fast AF ***
