i see.. so i need a lens that is 23.5mm thread (looking at the meopta site) and I've seen a schnieder lens that is 22 or 29mm ... does anyone know which lens i could get that is a 23.5mm thread?
It is maybe better solution for you to buy enlarger's lens board for 39mm thread lenses. Just because lenses with 39mm thread are easier to find. And enlarger lens boards are also easy to find (or to make). If you don't do that, then you need to find lens with 23.5mm thread.
As I said before I use Meopta Opemus 5 and Magnifax 4, and I use for both enlargers lenses with 39mm thread. I got Magifax with 39mm board. But, I bough Opemus 5 with 23.5mm thread lens board, and I just bought directly from Meopta lens board with 39mm thread for that enlarger. I belive it costed me about 10 USD, it was almost 10 years ago...
If you decide to go with 23.5mm lenses, Meopta's Anarets are maybe easiest choice.
