It's pretty obvious that the 7D2 is for fast action stills shooters first and foremost...not cinematographers.
With that said, this camera finally gives fast action still shooters the ability to capture video (that isn't constantly out of focus) using the dual pixel AF capabilities.
This camera is great for sport/action photographers that want to add some quality video to their coverage of a game/event....and this is all it's supposed to be. Go elsewhere if you're a dedicated video shooter.
And if they'd included, or especially added to the 3x digital video crop mode that's already in the 70D, it would have been even better for sports and wildlife videos.
The lack of it has me considering whether I want this camera for the speed and focusing or the 70D for its video features and WiFi (which I'd use for camera control).
3X crop mode would have been nice for sports..you're right.
