Sort of, what he omitted to say was that the sensor noise is by far the largest noise source in the system. A 22 or 12 bit ADC should theoretically be able to record the full output range of the CCD used in the K10D, there may be advantages going out to 16bits but in reality 22 bits is more of a marketing tool. The 22 bit ADC chip is a modular component which is designed to be used in all sorts of systems with many types of image sensors. In the case of the sensor used in the K10D it's pretty severely under utilized. The real advantage of the system wasn't actually discussed. If you want to read a detailed explanation about the supposed advantages of the ADC chip employed see: http://www.nucoretech.com/nu3/images/80_downloads/pres_technology.ppt.us.pdf Cheers, -- Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://home.swiftdsl.com.au/~distudio//publications/ Pentax user since 1986, PDMLer since 1998 -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
