Hi Michael: My lens had the usual instruction pamphlets in different languages, but also a separate notice about 2"x3" in size (also in several languages) advising to update the firmware "for optimum use of this lens".Interesting... I didn't see a note about that with my new 16-35. I'm sure my FW is 1.01, because it hasn't been updated. Seems to be working fine, but I'll update the FW on the camera.
Thanks for the note on this.

So at age 78, maybe it was not just dummy me that had firmware update problems.
Thanks all.
