@ikgroup: Thank you very much for your offer! You People are so kind here its amazing!!
Sadly since I live in Europe I guess its too expensive to deliver that board from Washington...but thousand thanks anyway!!!
@bryan Lee: I used the 75mm lens and it works perfectly for 35mm! but I can only enlarge as much as 18x25 (cm that is 7x10 cuz of my collumn) and I would like to go larger without having it projected to a wall!
To build my own lens board would be an alternative but I could get the SIRIOTUB 39 for just 16 and the only thing bugging me is the Diameter and if it fits into the Tube of my Durst!
So maybe I should have asked differenty
( the answer is 42 .. lol )
New question: can some of you guys measure the Diameter of your Durstīs lens boards (that should solve the question if they are compatible) cuz if they never changed the Diameter iīm pretty sure that recessed board would work for my enlarger + 50mm lens.
Thank you all very much!
