Oftentimes I find myself framing an image, pre-setting the focus and then physically moving in closer or further away as I try to get the most interesting part of the subject in focus. That's pretty much impossible to do with a tripod, and the IS definitely helps.
I never understood, what is the specific advantage of this hybrid IS?insanitybeard said:Also, I don't think this has been mentioned so far, apologies if it has, the 100L macro has the hybrid IS which is supposed to be more effective than normal IS in macro photography for correcting lens shift.

In flight insects?? IS won't help you with moving objects - so what if you can shoot @ 1/30? - image of live insect will be useless. Even flowers move in the wind, so again IS won't help. The L uses larger filters and needs an expensive adapter to mount the MR or MT flashes. If your primarily interested in macro, save your money and get a good flash and learn how to use it for handheld shots. If not, the IS may be of value. I've had the USM version almost from introduction and I've always been very pleased with the results and never wished it had IS, but I use it almost exclusively for macro [1:3 - 1:1 and beyond with tubes]. I have other lenses [w/ IS] for other shooting situations.
