Hi everyone
I'm trying to know when my 17-40 f/4 L USM was made with its serial number which is UG0221.

Fun thing is that I find 1992 the "G" . How is it possible for I thought this lens was made by Canon since 2003 ?

Thanks a lot

That's a date code not a serial number. There is a separate serial number.

Your code is February, 2018.
