Currently I'm working on a 75mm view-rokunar f/3.2, but can't get infinity - bellows is too long, and the tubes also (which is strange: 75mm - 45.46 register = 29.54mm so I thought I could get reasonably long focus... have managed maybe 2 feet so far.)
I have been tempted to try the enlarger lens with my bellows, but only have a 50mm Componon-S. I would definitely like to see the results from a longer lens!
