It's on-demand, just like the K-3. It adjust the focus much more slowly during recording.

it's dual pixel(PDAF on sensor...sort of thing)
so it can AF smoothly(with silent lens motor and firmware tune up) while mirror locked up in video mode
just my 2 cents!

To achieve decent AF with a Dslr lens you need phase detect AF (the ability to detect direction required to focus).

Afain all current Sony/toshiba sensor 3rd party implementations do not have hybrid AF capability therefore all Nikon/Pentax cannot focus quickly in Video mode as the sensor is CD only.

Sony use a translucent screen so do not need to remove the 'mirror' during live capture so PD is available in their dslr's and Canon have on chip hybrid AF.

So for video with full time AF (consumer IQ) Sony and Canon have the best solutions, But with Canon you need to ensure your model supports hybrid AF.

My opinion is that Samsung NX1 have better video AF than Sony and Canon.
Better or equal speed and precision with smoother in focus/out of focus transitions.
Sony is sometimes erratic and Canon is not so fast and precise as Sony.
This opinion includes A6300 but not 80D which is probably not better than 7Dm2 in terms of video AF.

The NX-1 is not a dslr it has CD optimised lens (and hybrid sensor) so is not related to this discussion.

Though very expensive for what it is , it is an impressive camera 15fps , -4ev , 205 PD points etc etc

Probably the best current crop CsC but with Samsung on the label will not rival sales of the Sony CsC's

I thought Ricoh recently patented some sort of dual-pixel af design...
