How to Determine the Age of a Canon Lens Updated - How is the Lookup Table Working for You?

With the Canon TS-E 90mm f/2.8L and 135mm f/4L Tilt-Shift Macro Lenses in house, I took a fresh look at the site's How to Determine the Age of a Canon Lens page. The answers in the serial number table lookup appear to be plausible for both lenses. So, I added the new year to the chart.

If you have acquired a new Canon lens in the last year or so, please take a moment to look up its date of manufacture. Then let us know if the answer appears to be correct for your lens. Or, at least approximately so as a few months of difference in the age of a lens is usually completely irrelevant unless there is a service notice issued and in that case, specific serial number ranges are provided.
