Date code help please

hi john whats the code or sn number
 
Hi

I don't have a lens from which I can look at the date code. I'm thinking about buying a lens from calumet who say they don't have any history on the lens? When reading the classified section of the forum I noticed that some people who are thinking about buying a lens that's advertised ask the seller for this information - I therefore wondered if they could convert the code into a date of manufacture or age of the lens?

Many thanks

The Canon date code on L lenses is additional to the serial number. AFAIK, nobody else publishes date code information. Only the manufacturer can translate the serial number.

This doesn't seem to be the case Richard. When Canon moved to 10 digit serial numbers on lenses without the traditional UX 0110 type date codes, they started a new system. The first two digits of the 10 digit number represent the month of assembly. This started with 38 representing January 2008 and incremented by 1 each month until reaching 97 in Dec 2012.

That rings a bell now you mention it Bob, but I didn't realise the numbers had been de-cyphered. Thanks :) Found this link on TDP http://www.the-digital-picture.com/Canon-Lenses/Canon-Lens-Aging.aspx
