dual pixel cmos autofocus
machine translated, but it seems that this is a completely new autofocus technology that works on the whole sensor surface. if it works well and software is implemented well (not like @ eos m first), it'd be awesome.
seems like both conventional and live view autofocus will be effective.
According to that link, the computational power required to use this new type of live view AF means that the Rebel series won't get it for a while. Sounds promising for the mirrorless crowd.
