at what point in taking pictures do IS play a major role? if i'm taking pictures outside at moderately cloudy->sunny days, do the IS play a huge role w/ the zooms? i'm trying to justify 500~ vs 1000~ in price for the non-is vs is version and i'm coming up blank. how many of you bought the non-is and wish you had gotten IS instead, even at the double cost?
We'll see how much money I can save!
