Yes. I can understand that. But what I'm trying to say is that I'm not sure I quite see how this affects only high ISO values (which everyone seems to be talking about.) Shouldn't these improvements mean there is less noise across the entire range - since the signal always has to travel though these circuits? (Or doesn't it?)
