I'm searching for a lens (135mm or so) for a Super Speed Graphic. I have been offered two. One is an immaculate Prontor SVS lens that came off came off a Polariod Pathfinder 110A. The other is the Rodenstock Optar, the 135mm that originally came with the camera. The Optar is not as pretty as the Prontor, but it is accurate and in good working order. Both are priced at $100. Pros and Cons? Help appreciated.
