It's strange, my N80 feels very natural to me because I've been shooting digital slrs for so long. My Nikkormat feels very natural to me because I grew up shooting a Pentax K1000. The FE feels less natural to me because it has some exposure automation like the N80 but has the manual focus of the manual camera.
I think the key is to find a way of creating a photograph so that the camera is a natural extension of the photographer's vision. Not a rigid interpretation of what is correct or incorrect.
