I'm new to digital cameras, and sick of getting the bad shot, but not knowing till they are developed. I would like at least a 6x zoom and I would be taking sports, landscape and family pictures (a wide variety). I have looked at many cameras, but can't decide which would be good (Kodak 6490, Minolta Z2 or Z3, Canon S1 IS and more). Price range would be anywhere up to $400. I appreciate any input to help! Thanks!!
