Quote from link: "This firmware update is for lenses equipped with firmware versions 1.0.5 or earlier. If the lens's firmware is already version 1.0.6, it is not necessary to update the firmware." (Emphasis added.)
I commend Canon for this fix, it was acknowledged very fast, so they pay attention to forums, ha! To punch out the firmware this fast is excellent service. Bravo!
And I suppose the world will never know if anything has been tweaked physically for the next production run...???
