Hey Chris,
I know this is very late, but I hope it is informative. I have never hiked the entirety of the AT, but I have hiked many sections of it. I can say from personal experience, the less weight the better. After a few weeks of hiking (especially in the Smokies), too much weight will give you a great reason to give up.
When I hike, I generally take a small digital p/s, mostly kept in a plastic bag. The camera is light and you can carry numerous SD or CF cards with almost no weight. I would say that film or an SLR is out of the question.
Hope this is helpful.
