As to the "fame" of the process, please: multi-coating was a JOINT effort of both Zeiss and Asahi, and Zeiss was first into the marketplace with the process, the "T*" coating first appearing on industrial and technical items produced by Oberkochen from 1969 onwards. We can argue all day whether Zeiss or Asahi first produced commercial camera lenses with multi-coating. I'm inclined to give the nod to Zeiss, by three months, but, at this remove, who cares? The two companies had pooled their research and results. Marc msmall@roanoke.infi.net FAX: +540/343-7315 Cha robh bas fir gun ghras fir!
