I've got a Kodak DC120, had it for years, taken it round the world four times. I know it's built like a brick but I'm strong enough to carry it What I'd like to do is upgrade it from its 1.2 megapixels to 4 or more megapixels. I know, it sounds daft but does anyone know if it's possible? I don't need advice on buying something more up to date, I have a couple of those but I just prefer the bulk of the DC120. V.
