Doesn't "process" indicate that the lens was intended for copy work at limited reduction. I think on an 8x10 camera it will be fine for any use. Do you make mostly contact prints? I have used a modern coated Wollensak Raptar 105mm surplus lens originally made for a copy machine mounted in an old Wollensak shutter (perfect fit) for 35 years on my 4x5 camera. I use for wideangle architectural photography. In my office we have 16" x 20" color enlargements made from transparencies that have amazing detail. Just because a lens was originally intended for a specific use doesn't mean that it will not work for other applications. Try it out.
