Hi Steve,
All the folk who are football fans are likely mesmerized by the games on TV after as Thanksgiving dinner was planned, shopped for, prepared and post-prandial resting too.
In addition a considerable fraction of folk have sons and daughters home and there's enough to play with play station in High Resolution and play the teams they wish with them moves they want and a case of beer between them!
So just me for the while! The IDsII is going to allow you to take the same scene with more pixels and has likely a higher signal to noise ratio too, perhaps. With more pixels, when you down res to print that same scene, the noise will be less.
When you see the higher ISO settings on these cameras, you are looking at different gain settings and in each case you are multiplying the noise as well as the data.
What were the conditions in which you noticed noise was handheld differently and what were the differences. When the light is less and the ISO is increased, the proportion of noise in the final image is increased.
What the camera needs is light!
