The only 4x5 camera I have owned is the Chamonix 045N-2. Its a really nice camera but I sometimes wonder having the focus knob in the centre just underneath the rear standard is a good idea. The more I look at the traditional rack an pinion design where your arms are out side the dark cloth to focus just seems a little more natural but I may be wrong.
The only thing I don't like about this setup, or any other LF camera that focuses only via the front standard, is that the sheer function of setting correct focus can change your composition; more critical when doing close-up work. Since I like to pay close attention to what's happening along the edges of my frame, I much prefer rear standard focus.
