Cambo WRS lenses are either Schneider or Rodenstock. Since Schneider have exited this market, only Rodenstock lenses can be purchased new, whereas Schneider are only available in the pre-owned market. The price also depends if the lens is mounted on a Cambo Tilt/Swing panel or normal panel. The cost of a lens in T/S panel can be 1-2K higher than the same lens in normal panel.
In general the SK lenses are relatively less expensive when compared to Rodenstock lenses.
