And The hybrid IS will shine on the standard zoom since it's wasted on real macro lenses like the 100L - the IS is nearly useless at very close distances.
By that logic, though, the Hybrid IS is equally useless on the 24-70/4L IS. The translational motion compensation, which is the 'hybrid' part of H-IS, is only effective with very close subjects; regular IS compensates for angular motion, which dominates for subjects beyond a couple of feet from the camera. That's why H-IS isn't used on other lenses. To get to the near-macro 0.7x mag with the 24-70/4 IS you're at the MFD of 20 cm, and the MFD of the 100L macro is 30 cm - further out than the new lens.
I wonder, is there any chance that this Hybrid IS is simply the non-mode-selectable type of IS I have on the new 28 IS? I seem to recall (sorry, no reference) reading something to the effect of the new 24 and 28 IS having a new mode of IS that simply auto-switched between a panning IS and a standard (all-purpose) IS based on the lens' movement. Any chance that is what Canon means with the new lenses' IS?
And for those not fond of the Hybrid IS with the 100L macro, though I agree that at macro focus distances the IS is less effective, two things I'd share from my use of that lens:
1) In my hands, it seems to work just fine in keeping slower shutters stable as traditional IS would, and
2) The 100L is not remotely a dedicated macro lens -- it's a fully functional 100mm prime. The 180L macro is
such a slow focuser that it's effectively a specialist lens (though I'm sure our forum's creative users have found neat ways to use it for more than as a macro). But to relegate the
100L to strictly macro work is a big miss, IMHO. One quick switch on focus range and it becomes a solid 100mm prime for portraiture, concerts, etc. Remember that not everyone owns the pro portrait staple lengths of 85 and 135, so the 100 is a great option for some.
