From Imaging Resource & SLRGear
The folks at Imaging resource have come up with their own way of testing the effectiveness of image stabilization in lenses. There first test subject? The 70-200 f/4L IS.

There is all sorts of charts and graphs and fun stuff to read.

The Verdict? At best, the 70-200 f/4L IS came away with a maximum improvement of 2.8 stops with IS turned on. That's pretty impressive. Canon claims “4 stops”, but we all know about the validity of manufacturer claims.

Yes, you'll get 30mpg if you're driving down a hill, newly paved, with the wind behind you on racing slicks and the engine off.

I'd like to see a good comparison of this lens and Sony's 70-200. What's better, in-body or in-lens? Get it done IR!
