i am not sure if you plan on shooting paper or film.
i lean towards paper for my 8x10 and bigger cause my kids
ate all the money i would have spent on film ... and i don't mind
long exposures ortho type grey rendering &c.
you mention older lenses ... you might consider one of reinhold's wollaston lenses !
he makes them big and small and from all reports they are a thing of beauty. ( he is a apug member ! )
the lenses come with waterhouse stops so you can stop down and get a sharp image if you want
or you can shoot wide open and get fun soft exposures. he also makes an adapter for a packard shutter
if you need an instantaneous exposure and he is developing a drop / guillotine shutter as well.
not expensive but ... gold
good luck !
