    Commercial Ektar serial numbers

    I understand Kodak's serial number code on Commercial Ektar lenses can be used t o determine what year the lens was manufactured. Can anyone share how the serial number code works?

    Commercial Ektar serial numbers

    Ron, I think this may be what you were thinking of: Starting in 1939 or 1940 the serial numaber has a two letter prefix. These stand for the last two digits of the year. The code word is: C A M E R O S I T Y 1 2 3 4 5 6 7 8 9 0 For example, a lens with the letters ES was made in 1947, one marked RC in 1951. roger

    Ron... there is a good discussion of the numbering system that Roger describes available on the web. The website also has a lot of good information on many classic and modern lenses. Info such as coatings, coverage, image quality, etc. The website is at Many other topics pertaining to large format photography are also discussed...- Dave
