p.s. about your comment regarding lines, scales, and detents... I actually have avoided cameras with too many. I think they are distractions and, except for some scientific purposes, undermines photography by giving too much data to worry about. I don't see it as a manufacturing issue, but more of a natural human tendency to worry about what we know (specifically, worry too much when we get too much data) and not worry so much about what we know less details about.
