Sony has released a demo video from the new Sony A7s – Sony A7s: Low Light Demonstration (ISO 1600 to 409600)- on SonyHowTo YouTube channel and the results are spectacular.
The noise levels at ISO40960 are obviously not acceptable for a professional work but you literally record a video in total darkness, I am sure some people will find ways to utilize this capability.
