Although it's obviously pushing the capabilities of this sensor to the limit, the increase in measurable noise from ISO 400 to 800 is not extreme. This is no doubt down to high levels of noise reduction - there is visible blotchiness and a serious loss of fine image detail. Usable, but only if you really need that extra stop of sensitivity.
