I'm starting to realize how slow LF cameras are, especially considering the weak DOF at moderate apertures, plus the fact that there's not Delta 3200 available (wouldn't that be awesome?). Once upon a time, these things used to be used with flashguns and flashbulbs. How were they sync'd up? Did you have to run a separate PC cord from the flash gun up to a PC terminal on the leaf shutter (assuming it had one)?
Also, is there some trick to focusing on the ground glass? I was setting my infinity stops using a simple loupe, and even at f/4.5 it seemed like finding the point of critical focus required a lot of interpolation. I could see the fresnel clearly in the loupe and the ground glass image seemed pretty course and of course, small. If one was blowing up big prints, I can imagine the best possible focus could be important.
