Determining the Age of a Canon Lens Based on Serial Number

To age a Canon lens using the 10-digital serial number Canon lenses, we dissect the serial number as:


The DD is the key to the date of manufacture of the lens – the date code. The long, narrow Canon lens date code chart is shown on the right side of this page.

They have posted what they predict to be the future date codes for Canon lenses. Please keep in mind that this is a work in progress and may not yet be definitive.

Canon Doing Away With Date Codes?

Where have they gone?
There have been reports from folks that Canon has removed standard date codes from their lenses. Chuck Westfall, Canon USA’s tech guru confirms the reports.

The new 70-200 f/2.8L IS II is reported to have a 10 digit serial number for some people. All of my stock at Lens Rentals Canada has a 6 digit serial number. Would the 10 digit number have a date code system? We’re still waiting to hear.
