I'm looking to buy a wide angle lens for my Canon T2i. I'm pretty sure I want something like the Canon 10mm-22mm or the Sigma 10mm-20mm 3.5 or 4-5.6. I'm wondering, though, since these lenses don't have IS, will they provide shaky video footage when handheld. I have a very steady hand, but all video cameras I've used have either optical stabilization or sony style stabilization.
I figure with such a wide angle, it may not be as noticeable if its a bit jumpy. But I can't seem to find a wide angle lens that has IS.
