It’s an interesting idea and a direction that all digital camera makers are obviously headed in. Every generation of digital camera will have higher ISOs with less noise than the previous batch. Now imagine just a little ways in the future when you can get the equivalent of ISO 12800 (3 stops faster than ISO 1600) with no noise. I could’ve used it today for sure. Three stops is the difference between shooting indoors under fluorescent lighting at 1600 and 200. High ISOs will never be a substitute for quality lighting but it’d sure be handy.
