... there's also the Olympus E500. The users' pool on Flickr is not a great inspiration. Whereas the Nikon D70 group is a very lively one, with a lot of most excellent pictures. There's a point where a practical decision will also be a cultural or even an emotional one. My first proper camera, twenty-odd years ago, was a Nikon EM. (The circumstances in which I lost touch with that are a whole other story).
So history and peer pressure are leading me towards the Nikon just now.
