Panasonic 42.5mm f/1.2 ASPH POWER OIS LEICA DG NOCTICRON
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.

The Panasonic 42.5mm f/1.2 Nocticron's Power O.I.S. system was useful, but not overly so. We saw about a 1-2 stop improvement with IS enabled for slower shutter speeds, however we don't have a stated manufacturer spec for how many stops the IS system is supposed to compensate.
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.
