I wonder how big the image circle is on that lens? I used to run a process camera in a print shop, and we could expose film up to either 16" or 20" wide (can't remember which, it's been 18 years). That camera used a Nikkor 480mm f/9 Apo. I'd assume a ~625mm process lens would have serious coverage and could possibly be used on a camera larger than an 8x10.
