I'm kind of humbled by the various voices here. I don't know, I had spoken with some people who talked about the various qualities of different lenses, and seemed to suggest that it would be worth having different brands. It's classic GAS, and I went with it. Probably a mistake, and my hunch is that I'll keep it in the back of my mind that one of them has to go. Probably the Rodenstock, because I paid more for it.
I probably let auction fever drive up what I paid for all three lenses, I was so excited to get my enlarger setup that I wanted to get some lenses that I was pretty confident would be issue free. Of course, that is still to be seen, and I'll be pretty picky with these given what I paid.
