This is at about or slightly beyond the limit of what the image stabilizer lenses can do for you, as the shot I took at 0.7s without a tripod shows. This particular shot is sharp because it was shot with a tripod, though in retrospect I probably should have tried it by hand just to see how bad the blur was. Still, it's significant that this is getting exposure similar to a 4 second shot also at f/5.6 in only half a second.
