U = Utsunomiya, Japan F = Fukushima, Japan O = Oita, Japan The second letter, "R", is a year code that indicates the year of manufacture.Canon increments this letter each year starting with A in 1986 and prior to that, A in 1960 without the leading factory code.
Determine the age of a Canon lens based on the 10-digit serial number To age a Canon lens using the 10-digital serial number, we dissect the serial number as follows: These dates should be viewed as approximations and should be used for your amusement as the estimates are not guaranteed correct. Note that Canon EOS DSLR camera body serial numbers, at least for 2013, do not follow this chart.Also please note that future dates shown in the table are predictions/expectations.The first letter, "U", indicates that the lens was made in Canon's Utsunomiya, Japan factory.Prior to 1986, this letter is moved to the last position of the date code.In part, the numbers might be shifted by a month or so. Special thanks go out to friend-of-the-site Norbert for his role in the development of this chart.
To determine the age of a pre-10-digit serial number Canon lens bearing a date code Until phasing out the practice starting in 2008, Canon included a date code beside the rear lens element of many (but not all) lenses (note that some 2012-manufactured lenses retain the date code).The remaining digits in the serial number, SSSSSSS, are a uniquely-identifying number of the lens – likely within the production month.Please note that, while the overall chart is holding out nicely with the lenses we've checked (including several late-2014 models), it is a work-in-process.This is a Canon internal code (that is occasionally omitted).You now know the manufacture date for your lens - But - You cannot know how long the lens was in inventory, in shipping transit and on a shelf until it was originally purchased (without having the original receipt or a reputable person accurately informing you).This month, we look at one part of the world which is defying the recent slowdown in trade growth, South East Asia.
