Well, the nice thing for us is that most of those applications went over to scanners (industrial grade drum scanners), making high-end process lenses quite affordable on the used market today. I cannibalized my own set of Apo Nikkors (not to be confused with El Nikkors) from a Japanese process camera 22 feet long, with a bellows big enough to walk through if it had been strong enough. I also kept the big precision vacuum easel. This copy camera was made for 1:1 copy from big art originals, and cost around $200,000 US when it was new back in the 70's. Processes lenses of that variety have to be corrected to a far higher standard than ordinary enlarging lenses; but they don't come in short focal lengths. I happen to do much of my color printing from 8x10 originals, either chromes or color negs, and sometimes print quite large, and expect optimal results. "Good enough" isn't good enough in that kind of work.
