Canon EF 24mm f/2.8 IS USM
Most people tend to think of image stabilization as being mainly for telephoto lenses. While it's true that their longer focal lengths tend to magnify the effects of camera shake, image stabilization can provde a very useful assist at wider angle focal lengths as well; anyone who's ever tried to blur the image of a waterfall, while keeping the surrounding landsape tack-sharp knows exactly what I'm talking about.
We see a pretty impressive amount of performance with the image stabilization system of the 24mm ƒ/2.8 IS USM; at least three and a half stops of hand-holding steadiness, with the potential to get stable shots as slow as half a second (and even some at a full second!).

IS systems tend to provide more benefit to less-stable shooters than very steady ones, so most users will see the same or greater amounts of shake reduction as we measured here. You can read more about our IS test methodology here: SLRgear IS Test Methodology, v2.
