interesting reading though, is the entry for "digital camera" in wikipedia, with lots of information about the importance of sensor size, as opposed to pixel count... i learned a bit about this trying to work out why my new 10 megapixel samsung is so rubbishy compared to my old canon 2megapixel... the size of the sensor affects directly the ability of the camera to capture undistorted pictures, and the older digital cameras had much bigger sensors relative to the original 35mm film format... modern "cheap" sensors are around 6x6mm, and the camera uses all sorts of digital techniques to compensate for fish eye effects... anyway, `nufff bla bla, i have alll my old cameras still, maybe if i get time i`ll set up a similar train to yours, and make a comparison between "old" and "new" digicams.
very interesting subject tho, if it dosent already have a thread, maybe photography should get one here, then we can really go into things like coulour(liveries) and how differently people percieve them, and what factors influence that perception!
