NEX 6 A few Questions

Hi Folks,

I am looking to get a NEX 6 and subsequently have a few questions :

1. Does it have any Cross Type Sensors; if so, how are they spread out?

2. If it has Cross Type Sensors, how do they work with the flexible focus that you move around the VF?

3. Can older Nex Lenses be patched to work with Nex 6?

Many thanks,

Dan
