- My CALUMET catalog lists the Caltar 210mm f5.6 for $550. CALUMET says
- their house brand is Rodenstock and the 210mm f5.6 is a SIRONAR-N.
- CALUMET offers a free lensboard and drilling and mounting with a new lens
- purchase, CALUMET or CAMBO lensboards only. I just ordered one. Should
- be here today.
