I am selling my 4x5 150mm f/5.6 Rodenstock Sironar-N lens as I have recently moved up to a lens that has wider coverage. I have had it in service for many years and it was always one of my favourite lenses. The lens still works well and is in good condition with Rodenstock caps; most recently it was used on my Linhof Technikardan. $360 OBO and domestic shipping only (I am based in NYC). Photos below and feel free to hit me with any questions that you may have.
Andrew.
