While the advantage of IS is certainly most pronounced at slower shutter
speeds, its use guarantees a greater percentage of all shots taken will be
keepers, provided the rest of the technique is there. Even a 1/500 shot can
be irritatingly unsharp. IS will not cure all ills but it can give a
working pro a higher percentage of keepers in dynamic situations.
A 70-200 f2 would be too large and unwieldy to use in the same way the
current lenses are. It would, however, make for a much more interesting
f4.5 with the 2x converter! Then again, the promise of DO could let both of
us have our cake and eat it too: a 70-200 f1.8 DO IS would probably size
out similar to today's lens. Of course such a lens is pure and
poorly-informed conjecture on my part. I'm still loyal to my trusty 80-200
f2.8L! ;>
