I have spent the last year waiting for the MF (Unicon 85 or Unicon 105) condenser for my Durst M700 to show up on eBay, and I'm thinking that I need to do something about it, instead of waiting. I'm thinking of getting my hands on a condenser lens from some other MF enlarger, and adapting it to my M700 by making a custom box to fit it into the head. I only want to be able to print 6x6 for now. Is this a bad idea? Do I need to worry about distances to the mirror or to the negative? Has anyone done this? I'd appreciate any input at all. Thanks!
