Although very grainy the A570's ISO 800 output is by no means unusable; the light-handed approach to noise reduction preserves more detail (and looks a lot sharper) and would be fine for smaller prints where absolute image quality wasn't the be all and end all. By comparison the Casio's excessive noise reduction has a destructive effect on detail and the whole image has decended into a blurry mess. Neither camera is producing results you'd want to use for anything important, but the Canon effort is visibly better. The A570 IS also has an ISO 1600 mode, but this is much noisier and loses a lot more detail to noise reduction and, to be honest, is best avoided unless there's no alternative.
