I bought this lens with the Canon 60D, and I use it on a 40D for the imaging company I work for. My work needs a zoom and I chose this over the 17-85mm that I sold recently. My backup lens to the 18-135mm is actually the 18-55mm.

Zoom range; image quality; versatility; price

Slow aperture

I read the reviews and thought I'd take a chance. You certainly get what you pay for. I won't ever use this lens and now I need to save up for a real lens before I can make money with my camera. Disappointment does not begin to describe my feelings.

Easily Interchangeable; Consistent Output; Durable

Only for baby pics; Lens Creep; Poor in Low Light

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

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

I do portait, indoors and outdoor photography. This lens allows me to be in many places at one time sort of speak. Tt's range and ease make it so I can shoot in good light and in semi low light conditions. With great results.

I purchased this lens for my SLR camera and i must say that i did try a few different lens and this 1 seemed to come out on top, It has a more imprssive exposure than most of its competiters and helps give the crisp and clean effect most people want from they're pictures.

Brilliant clear exposure

no diadvantages yet

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'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.

Its optics are great, and it has unusually great handling. It is a very sturdy lens; almost the entire body is the zoom ring, and zooming and focus are a breeze. Close focus is only 1.5 feet (0.45 meters), so if you can see it, you can shoot it!
