(At the bottom of his "Tech Tips" column there's a link to send him an email...and a couple of days later he replied!) I think he's stopped doing the "Tech Tips" (I can't any since early this year) but obviously he still receives emails.
Well, he did. I e-mailed him and that was his reply:
Bryan contacted me directly via e-mail. Here is what I told him:
"I can confirm that the serial numbers for L-series lenses have shifted to a new 10-digit style as of 2nd-Half 2010 production. However, Canon is not releasing any further information on this topic."
I'm not at liberty to comment any further on the new style of lens serial numbers.
