Says:Hi,I was wondering about the serial numbers of the Fujinon XF lenses. Looking at the ones I have, and ones I've seen others have, it seems to me that the first digit of the serial number is the last digit of the year of manufacture, e.g., my lenses begin with:21A - 201222A - 201232A - 201338A - 201345A - 2014The first digit = year of manufacture hypothesis matches perfectly so far.However, the second digit seems mysterious. I read some speculation elsewhere that it is the quarter of manufacture, i.e., 21A would be 2012 Q1, but clearly it doesn't hold for the 38A and the 45A.

Someone suggested that they've changed the second digit to reflect the month of manufacture, but even that cannot be true since the 38A was bought in July 2013 and especially the 45A I got today and it's only March.Anyone else been thinking about this? =)Originally posted at 2:14PM, 12 March 2014 PDTArkku edited this topic 66 months ago.says:Yes, I was wondering about that too. The quarter theory or the month theory don't stand for me neither. I just bought a 18-55 with the serial number 48A, and we are just beginning of May, 2014. This, though, could match your 45A from March if we would consider the second number refers to a manufacture batch or something like this.65 months agosays:On the other hand, if they're already at batch #8 in April, what happens after #9?65 months ago.
