Anybody have one? A quick search of some reviews turned up some good remarks. I'm looking to shoot some close range shots, like around the house and stuff. The price looks really good and I don't expect it to perform like a 600 dollar lens, just better than my crappy kit lens. The kit lens is 18-55 and takes some mediocre at best shots, it seems to be very picky about motion while shooting. Does the IS make a big difference??
