Firmware changes:
Firmware Version 1.1.1 incorporates the following enhancement:

Good thing that Canon is doing this.
On the other hand.....what is going on with the Quality Assurance at Canon?

I wouldn't necessarily call it a quality assurance issue. Canon has just developed a brand new 61pt AF system and drive in their new pro bodies that has some advanced capabilities not previously used. Seeing as all of these lenses were designed and announced well before the 1D X was even announced, let alone released, its not surprising they have an update to these lenses that would fully support their new AF system.

+1. At least Canon is willing to update/fix these issues when new technologies/products are introduced. 3rd party manufactuers can also run into these issues as well, but how often would they acknowledge and fix the issue?
