When looking at the photos carefully I noticed that the focus track slides through a shorter "keeper" track attached to the bed of the camera. The focus track is held in place only by a short 3-4 inch metal piece up front with a dovetail inner shape. On the Chamonix and I think the Phillips that sort of piece runs the length of the bed, all the way back to near the focus knob.
Seems like the front standard and lens and focus track might sag downward at the front as the weight of it are extended outward - kind of pivot on a too short "keeper" at the front of the bed.
Any thoughts?
