Cons: Build quality in accordance with price - low, that is. Slow and slightly soft at the long end. Manual focusing is painful. Filter thread rotates (think polarizers...).

Pros: Best value for money in Canon lineup. Very good image quality across the range, save for 55mm. Useful stabilization. Very compact and lightweight.

Summary: This lens came as kit lens with my 450D (XSi). It's size and weight makes it a perfect companion for travel and hiking. The focal length range is well adapted for general use. I recommend to get this lens with your XXXD body at first. You may then find out where you need more range or more light and invest accordingly. You can sell this lens at almost no loss.

Cons: I am having a problem with this lens. The auto-focus stoped working afer 2,5 years! After some research. I found that this problem is commun. There's a flexible flat cable that breaks with use. The cable is not expansive but the repair is dificult for beginers.

Pros: Versality. Price. This lens is not expensive.

Summary: Good lens for the asked price. The "cable proble" will get you sooner or later.

Cons: * Not the sharpest * Okay build for a kit lens, very plastic. I dropped it with the camera (XSi), the mount broke, but no effect on IQ which is not bad.

Pros: * Very cheap * 3 stop IS * Slightly less sharper than its 17-55 counterpart * MTF resolution across all zoom and all f-stop is crazy-good

Summary: Highly highly recommend!!

Cons: Awful toy-like build quality, awful manual focus ring, very unsharp after 40-45mm, rotating filter thread, slow apertures which need to be further stopped down, noisy and slow autofocus, washed colours, pics always need to be edited via software.

Pros: Almost inexpensive when bought as a camera kit or second-hand, very sharp in the 24-35mm range at f/5.6, IS system, autofocus is precise.

Summary: Pics are very good only in a quite narrow sweetspot, you will very likely want to replace it as soon as possible with a more useful lens. Second-hand market often offers good bargains.

Cons: rotating front element, precise zooming near 18mm is difficult, very soft at 18 & 55mm wide open

Pros: light, cheap, sharp at 35mm, good beginners lens

Summary: I have owned this lens since January 2011, and I have taken around 3,000 shots with it so far. The lens is OK for most every-day photography, but I have have ruined a few (20 or so) shots with the lens being so soft at 18mm. Cromatic abberation (color shift) is also a slight annoyance at the wider end of the zoom range. I think this lens is very good for a begginer who has just bought this lens with a camera, but eventually you will want to upgrade to a better lens. My advice is to use this lens as a backup to a better lens. The image stabilization is wonderfull and works well at 1/8 sec upwards (18mm) and 1/13 sec upwards (55mm). Overall, I am fairly pleased with the lens, but if I had bought a camera body only and had the choice of buying a different lens, I would be a fair bit happier with a different lens.

Cons: Great Price/Performance factor Quite ok Macro performance for such class lens Small and light

Pros: Rotating AF Ring, which makes CPL Filter usage painfull Plastic everywhere Lens is not very bright Motor is slow

Summary: Lens does it's job for it's money very well, but if you need to use filters frequently, or shoot in low light conditions, then upgrade to non-rotating and faster lens is needed.
