jeanette-

Generally speaking when the CCD or the camera's imager is somewhat larger, there is less potential for noise in low light level shooting conditions at high ISO settings because the pixel density is lower, providing all of the other design parameters were properly attended to in the camera design.

However, in this case, as I read it, you are talking about two differnet imagers of varying pixel counts. I will let the mathematicians work out the mathematics of pixel density in each of these imagers. So for right now, you know the theory involved, we will have to await the results of the pixel density calculations on each imager. I hope this helps.

SX100 sensor is 1/2.5" in size but G7' is 1/1.8" - much larger and so is better

Correct! A630, A640, A650, G7 and G9 have large sensors, while the others have small ones.
