hey guys, as you can tell, im new here, and new to photography i'm currently a graphic design student, and whenever i wanna take some pictures to use in my design, my ancient sony P7 just ain't cutting it, especially for close up shots where everything just turn into a blur... So i'm looking for a new camera The one im interested in so far is the canon a640, both the price and quality seems pretty good, and the reviews i have read seems to be quite positive. But the thing is it doesn't come with IS, and i was wondering how much different would it make? I read that with a tripod everything should be fine, but i doubt i would be carrying a tripod with me all the time.... Basically i just want a camera that can take really good quality pictures whenever i see something interesting, so i won't always get the chance to hold the camera very still or use a tripod. So would IS be really important? and any other suggestions for other cameras are more than welcome!
