Heh, the inter-galactic thread returns for another appearance. Some time after my 2007 post(!), I clicked my ePrey Bronica search bookmark just before shutting down the computer for the night. Behold - an f4.5 1:1 for $295, buy it now. It looked to be in excellent shape, so what the hey, "CLICK." I admit I haven't done a whole lot with it, but I was thoroughly impressed with it. It's a serious handful of metal and glass, slightly over two pounds (923 g).
I actually have a project in mind that would give it a workout, but I need some early spring lighting at my intended location. In general the Bronica lenses (and probably most similar beasties) don't focus down very close, so it's nice to have one you can just keep cranking in.
