I found a Calumet monorail in 4x5 with a Rodenstock APO Sironar N f/5.6 and a Polaroid back that takes type 52. The store is pretty motivated to move it because it has been collecting dust for so long. They quoted me $600 for everything including a nice tripod which I forgot to mention earlier. I did some checking on the lens and it is supposed to be a nice performer, but does anyone have any first hand experience with it, and how does that price stack up? Here is a picture I snapped.
