Image stabilization; who has the best?

I don't know about you and EinsteinsGhost, but in my experience, there is almost always some kind of action when I use long focal lengths. Apart from the occasional moon shot, I can't remember using long focal lengths for still subjects.

And if there is action, I need some rather high shutter speed anyway, no matter how good the image stabilization is. I pretty much agree that 2 stops of stabilization help is all I can utilize without getting motion blur from subject movement.

So that leaves the short focal lengths. I sometimes shoot non-moving subjects at short focal lengths, but most of the time it is only slow-moving objects like living humans or leaves in trees. With a 2 stop improvement it should be possible to hand hold an APS-C camera at around 1/10 of a second at 28 mm focal length. If the shutter speed get slower than that, even a slow-moving subject will be blurred.

So yes, if you are taking photos of really non-moving subjects, you may be able to utilize more than 2 stops of stabilization improvement. But if you shoot action or slow-moving subjects, I doubt it.
