I was under the impression that a CCD was inherently less noisy than a CMOS sensor, in an apples for apples comparison. As I understand it, the reason to use CMOS was cost and power consumption. The reason why Nikon has better ISO noise performance is their use of a CCD but they also have much shorter battery life.


Is the 75% noise reduction a function of the noise generated by the chip (which would be very good) or is it noise reduction algorithms (which is not so good since this reduces image quality).


Happy to be corrected.
