Pao,
I do not have one, but had a long discussion with may good friend, Will Thompson, who is our resident technical Canon speicalist and guru:
Better auto ISO implementation control
Can specify minimum shutter speed, (like 7DMark II, 5DS, 1DxMarkII)
Higher pixel count
30MP versus 20MP in 5D II and 5D III
Dual Pixel Advantages
- Tracking
- Dual Pixel focus to f11 in live view
- In video holds the focus as it is happening.
That's a start!
