This lens was the first lens with IS, and AFAIK, is still basically the same design today, as when first introduced. The latest 70-200, for example, is now the third generation of IS, and, as one would expect, is superior. It is a good lens, and does the job. > > I have also been told that the IS function on this particular > IS lens does not > support panning, meaning that it will record the panning > movement as a > lensmovement and then try to compensate resulting in even > softer pictures than > this optical design already gives.

This offers a number of advantages, and when used with a 1.4 tc, gives a maximum focal length of 280mm. It obviously costs and weighs more. If you want IS on a lens of that range, and the your budget is limited, then it fits the bill. If you don't want the IS, then look at other alternatives. As far as the quality of the optics is concerned, you will only get significantly better by going for the L lenses, but even some of these are not better.
