Are you asking at what point the signal-to-noise ratio becomes more
importatant than pixel count?
Sounds like a pretty simple question, but it is not. A small sensor 2mp
camera is adequate for web use. An astronomer wants a camera that is not
going to generate a noise pixel when the point sources he is
photographing may only be one pixel wide (I believe they work around
that by comparing multiple images taken a few minutes apart. The stars
seem to move the noise usually doesn't). I think that right now in
consumer grade sensors a 6mp APS size sensor is about optimum which may
explain why the makers don't seem to be in any great hurry to increase
megapixel counts on the semipro cameras.
