Ultra-wide zoom lens with a high zoom ratio. By having multiple lens groups move during zooming, the lens could be made compact and lightweight. The aspherical element suppresses distortion. High contrast is maintained at all focal lengths and sharp images are obtained.

Good sharpness and contrast; Quick focus and quiet USM
Hard to reuse accessaries as it is 67mm in diameter; Bad zoom creep
I bought this lens (used but in very good condition) on ebay for a £100 to replace the 18-55mm kit lens on the 350D. So please bear that in mind when you read this review.
The build quality:
The build quality is average. It has a metal mount as you can see in the picture. The zoom ring has a fairly narrow strip of soft black rubber but it provides the necessary grip so it isn't an issue for me. The manual focus ring is even narrower but if you intend to use AF 99% of the time, then it should not be a problem.
The zoom creep is pretty bad so if you are taking photos with the lens pointing at an angle upwards or downwards you would have to hold the zoom in place by hand (not ideal if you are using a slow shutter speed, as it might cause camera shake even on a tripod).
It is a 67mm diameter lens so be prepared to pay a bit more for filters and lenshood. It is not a popular diameter so you probably won't be able to reuse the accessaries on your other lenses.
The picture quality:
Very sharp throughout the zoom range as long as you are not shooting wide open at 24mm (a bit soft, not disasteriously so). For landscape, 24mm@f8 produces very sharp images still. f8-f16 will give you pin sharp images for the rest of the range.
Distortion is only slightly noticable at the 24mm and the 85mm end but you can usually sort this out with software afterwards.
The colour is punchy, so no complaints.
USM - very quiet and focusing is very fast
I like this lens quite a lot. The sharpness and colour you get from it is a total surprise. Obviously the build quality is not as good as an L lens but that is a given. I know 24mm is not as wide on a APS-C sized sensor but 24-85mm is a very useful range for an amateur like myself.
