IS technology is impressive on the new super teles (I rented an EF300 2.8L IS), and 70-200 2.8L IS zoom when used within its' limits. But IS just can't give me back the two stops of shutter speed I need to freeze subject motion that a faster lens can and IS seems to slow down AF capture speed and tracking. So for ME, more often than not IS stays switched off.
------------------------------------------------------------------ Yes Chip, Sometimes though after 1/2000 seconds it is pointless using higher speeds unless you need the wider aperture. I think your view of IS is very myopic. IS can save you when you at times when you need something called depth-of-field and slower shutter speeds (brides in churches) when you cannot run back to your car for a tripod. Newer IS telephoto lenses also have a special setting for panning. I use this with focus tracking and results are excellent. Let me also give you an example of where you benefit from an IS lens. I was on a small plane tracking another propeller-driven plane (B24 & B17) and the IS lens allowed me to stabilize the image and use 1/250 secs to blur the propeller. A colleague had a non-IS and had to use 1/500 seconds and higher to avoid blur which of course froze the propeller in the image. A funny looking shot that way. IS is the true differentiator between EOS and others SLRs.
