Amen to that! One "little" detail that many seem to forget! One comment to add to the "shooting indoor/low light, etc." situation is that this will also depend on what you're shooting. If its moving then IS isn't going to be of any value.
I own the non-IS 70-200 f/2.8 and love it. It's considerably lighter and easier to fit into my shooting bag than the IS version would be. My main subects for that lens are motorsports events, so the IS would be of no value there. Price is also a consideration, that IS II model is really expensive!!
I disagree. The photo I posted above the couple was moving towards me. I could not have shot that photo without IS as there is no way I can hand hold a 200mm lens at 1/80 sec and get a sharp image.
This is a wedding photo forum so low light is part and parcel of what we do. Moving subjects are hard enough to capture at slow shutter speeds but it can be done and IS makes the job possible.
