DEAR LIST MEMBERS WHO REALLY KNOW THEIR OPTICS.
    I have acquired an 8X10 enlarger merely for the cost of shipping which
wasn't cheap but better than paying a purchase price as well! It has no
lenses. I have everything I need up to 4X5 but need to get a lens for
enlarging my 8X10 negs. I know that anything between 300mm and 360mm would
be fine
    MY question: Can one use a process lens for enlarging. By "Process" I
mean a lens from a graphic arts camera that was used to make separation negs
before we had scanners. I understand they are flat field, often
Apochromatic to focus the seps at the same plane, and seem to work in the
correct magnification range. One might argue that they are/were more
expensive than enlarging lenses but with the conversion to digital prepress
there are quite a few of these lenses languishing on the shelves at printing
companies who would be happy to get some cash to invest in the next
generation of
digital prepress. They can be had very reasonably. Of course, nothing is
reasonable if it doesn't work.
    I think this is on topic because I will be using this enlarger to make
enlarged interpos/negs from 4X5, 5X7, and 8X10 negs for alt processes as
well as silver/gel enlargements. And, heck, it is an interesting
question...yes?
                                                            CHEERS!
