At 3:17 into Canon, Inc.'s Mario Nette video, the Canon EF 24-70mm f/2.8 L IS II USM Lens is credited for some of the scenes.
While the thought of a Canon EF 24-70mm f/2.8 L IS II USM Lens is very fun, it is surely just a typo. We have not even seen a version I Canon EF 24-70mm f/2.8 L IS USM Lens yet. (thanks Fredrik)
