Hi,

we are new to this forum, posting from Barcelona.

We recently bought a Durst 138 enlarger with a Laborator 138 light head, condensers Latico 240 and 130, old piece of art, but we got it to work. Comes with 210, 150 and 105 Schneider Kreuznach lenses. As there was no bulb inside, we mounted a 24V/250Watts Halogen Bulb (too strong?). So, Paola was working on our Durst CLS 450 until now with 6x6 negative format and as we put this negative into the 138, the resulting picture was pretty small. So we tried a 80mm and a 75mm lens from the other enlarger Durst CLS 450. They both fit into the lensboard and the resulting picture is big now, but we cannot get it to focus until we are very close to the lens, means very small picture again. For some focal length reason these lenses won't work on the 138. What is the reason? Wrong lens? Or can we adjust some settings on the enlarger to use these lenses? We are missing something....

Thanks a lot for helping us.
Cheers Paola & Lucian
