Correct. The chip technology itself is always changing which generally requires totally different technology around it to make it work. For sharpness CCD chips are going from front illumination to rear illumination because it eliminates the illumination hardware in front of the CCD pixel which the light has to filter through. However rear illumination has its own physical difficulties because to reach the same light recording levels the separation of the light has to be as little as possible, meaning the CCD array needs to be only around 10 microns thick. The only upgrades I've seen for CCD hardware is in the design and manufacture of a new version of the same chip array with some new performance like increased sensitivity to various light levels and reduced noise. Like going from the regular to the Kodak E CCD chips. Kent Gittings

The possibility of an earlier camera being upgradeable is very close to zero. --Mike - This message is from the Pentax-Discuss Mail List.
