I was playing around, and took all of these without a flash. Also, that ornament below was taken this morning, with flash. So I'm already happy about this camera. It's SOO much better than our old digital, it's not even in the same league.
These last two are in low light, with a high ISO setting. But they aren't blurry! A little grainy, but definitely not blurry or streaky. I've even got foliage and firework settings!
