I've been teaching myself digital camera jargon in preparation for a *istD. Finding that some cameras have CMOS sensors, and others have a CCD, I did some searching and found some useful web pages:
http://electronics.howstuffworks.com/digital-camera3.htm http://www.kodak.com/US/en/corp/researchDevelopment/technologyFeatures/cmos.shtml To summarise: the *istD is CCD, which is the longer-established technology. It's expensive and uses a lot of power, but best for sensitivity and noise, at present. --- John Dallman [EMAIL PROTECTED]
