Okay, so I actually got this today. The lens is a Schneider, and it's 50mm. So...need a 75 or 80. The negative carrier is the one that works for both 35mm and 6x6, so I should have no issues there. It has both the 35mm and 6x6 condenser, so I'm good there. And it WORKS, so that's another plus. I need a set of filters and the other lens and I can print.

WTB section, here I come!
