Does your 70-300IS have a serial number with 0 or 1 in the third digit?

They did it! A service bulletin to correct this error.

It only took four months!

Well, won't "KVDMBERG" be happy? Karin was real big on getting this trouble-making piece of... glass, despite its vertical malarkey.

Oh well... better late than... whenever!
