CCD have better basic image quality but are much more expensive to make and, since they use more current, tend to run hotter and hence noisier and use up batteries faster than cmos. The fact that as they heat up noise gets worse rather rules them out for live view too. cheers, Frank On 1 Mar, 2010, at 03:17, Jayanand Govindaraj wrote: > George, > If I remember right, CCD sensors have better noise characteristics than > CMOS > ones.
