For example, the Canon 1Ds (version 1) has a big sensor, but the image quality at high ISO/longer exposure is not as good as, say the Canon 20D. One reason for this is because the CMOS chip used in the 20D consumes less power and generates less heat than the CCD sensor on the D1s. Heat is a noise generator for the sensor. (To optimize image quality on your digital digital camera, don't use the preview screen much !) The comparison in discusssion is a "system" comparison, from which conclusions about separate components are not always valid. My humble, biased opinion - Phong
