Hi Steven, this would interest me as well! It would be interesting to know somebody with an early kodak DSLR! I will try to ask at local agencies how their first Nikon D1 were doing now. I think there are few things to look out in aging: 1) colour dyes. Change over time AND change with exposure to light. I really don't know what the mosaic colour filters are made of, although Kodak might have revealed it in one of their technical PDFs. 2) the "transistors" themselves in the CCD/CMOS. In analogy to computers, whose CPUs can develop something like hotspots over time (especially if overclocked or ran at higher voltages). These hotspots are areas of worse conductivity? I am not an expert, and it's been a while since I read that article. So the imaging chip itself could age as well, with hard usage. 3) the chips responsible for the image processing and other "computer" tasks - well, the first computerised cameras (AE1?,T90, F4, even LX has some little chips inside, no?) are still working, so this shouldn't be much of a problem if they are designed properly. 4) the other things are just the same as in film cameras - shutter, AF, ... If somebody with more technical expertise knows about the first two points, tell us please! When things get more comlex, just more bad can happen... I want a Luddite digital!!! :) Frantisek
