I have a nice Componon-S 135mm enlarging lens that has a 42mm thread.
I am trying to mount this on a Saunders recent model 4500 series enlarger lens board mount.
Unfortunately, Saunders doesn't seem to make a lens board with this thread- only a 39mm, 50mm, or 52mm.
Do you know if there is a 42mm ring that would adapt this lens to a 50mm lens board, or 52mm lensboard, or know of any other options?
I hate to lose the use of my nice Componon-S lens!
Thanks for any response, even a negative one, so I can end my quest,
