I bought this lens as a kit together with a 550D and I can really recommend to invest a bit more and choose this lens rather than going for the 18-55mm kit version. From my perspective, the focal length of the Canon EF-S 18-135mm covers really a wide range of shooting situations.

Consistent Output; Durable; Quick Focus; Sharp Focus

I have had this lens for about a month now and used it quite a lot, I am taking photos almost every day. I also had the previous version of this lens which was OK but didn't get that much use.

For 90% of my photos this will replace my 18-55 and my 55-250 lenses

I have owned a Canon EF-S 18-135 for 18 months. I would categorize this lens as "adequate" as a kit lens, but not worth purchasing separately. The build quality is reasonably good but not great, and the image stabilization very good, but unfortunately the other features are limited and the optical...

I purchased the 18-135mm f/3.5-5.6 IS around 12 months ago in time for a family trip to the USA as a step up from the standard 18-55mm lens. The appeal was the greater zoom range and I figured it would be a great walkabout lens.

Easy to use

Poor build quality

If you are going to buy your first Canon DSLR like the 1100D, 550D or even the 60D then do opt for the better kit lens, that is the Canon 18-135. Why? Well you will outgrow the 18-55 soon. Optically this one is far better than the 18-55 kit and you will have this on your camera for a longer time.

Works fine as expected.

very good lens, very sharp and smooth ,great carry around lens, leave it on my canon 500d always unless want the 55-250is for distance.

Very versatile, the quality of this lens is superb, giving me clean, clear shots under all lighting conditions in the field...in any terrain, and from most angles. The range (18-135mm) enables me to easily frame the old barns and sheds I photographin the way I want to frame them.

Consistent Output; Easily Interchangeable; Fast / accurate auto-focus; Lightweight

I've been using an EF-S 18-55mm F3.5-5.6 lens on my old Rebel, which was the crappy one that came with the camera, forever. It's taken me years to decide on a general purpose lens that would take the place of the one I'm employing.
