mmm... I'm not sure because I haven't seen it yet, but the enlarger I bought should have three lens adapters; one is where the Componon 80 is placed. The other ones have a M39 mount as well. The 150mm and the 180mm you're talking about are threaded in such way or they require a larger hole?

Durst suggests to use a specific lens in combination with specific condensers. Does image quality changes a lot if I use a different lens but same set of condensors? Or shall I change also those as well if I use another lens than the one suggested?

thank you
