I don't have a macro lens yet, but my understanding from reading others' posts here is that IS would be very important for handheld macro work, and still may not make enough difference. I preemptively got a good tripod this week just in case. You may want to consider the same tactic.


This also leads me to suggest the Canon 100mm f/2.8 L IS, since it has the most advanced hybrid IS system in any Canon lens to date, a precursor to IS in future lenses.
