[a6300] Dual Pixel AF (Canon) vs 4D Focus (Sony)?

Now that the a6300 is released, it has added to my headache of replacing my 2-yo 6D.

Sony seems to have upgraded their AF system in the a6000 and made it way better (faster+more accurate) in the a6300. Here are my questions:
1. How is the a6000's AF vs a7Rii's AF in terms of accuracy, consistency and speed? (asking a6000 since a6300 not available for order yet)
2. How does Canon's Dual pixel AF (e.g. 70D) compare to a6000 when it comes to video and stills? Same parameters apply - accuracy, consistency and speed

I'm leaning towards video more and more these days, and highly reliable AF-tracking will be useful in terms of video-ing running kids and stuff without me having to fiddle with AF point selection or manual focus. Looking forward to the comments!
 
I can't comment on the Sony AF but I have the 70D and have used its AF for tracking moving subjects in video a lot. It's the easiest AF to use I've come across, particularly because of the touch screen. My C100 II has the same AF (DPAF) and also works very well but isn't quite as easy to use because it lacks the touch screen. Obviously there are times in video when manual focus is preferred but if you're tracking the subject matter you mention it works very well. If possible I recommend you try them both and see which suits you best. I know from using a Sony NEX7 as well as my Canons that there is quite a difference in the colour of the videos. IMO the biggest issue is figuring out which camera feels right to you.
 
just curious - is the AF point area resizeable (just like on the GH cameras?) on all the sample videos I've seen, the AF box is so huge that it covers the entire face, rather than being useful enough for 1 specific point.

I'd figure Canon wins in the color science department?

From what Ive seen from people who have used it on youtube, it seems like individual AF points are not selectable. Strange omission, but not surprising since the a6000 is the same way.

When you have 19 AF points or whatever the 70d has it's not too cumbersome moving between them, with 400+ it's not as quick to scroll through them. On the A7rII you can move the AF box anywhere in the AF point coverage and you can change the size, I've never found not being able to select individual points to be an issue, but that's just me.

sounds like the a6xxx series is intentionally crippled then. I can't imagine having to MF on my adapted Canon 24-70ii or rely on face auto-detect, which is not reliable as its native options.

By the way, is there a native 24-70 f2.8 option for Sony's APS-C line? or do we have to get the GM lenses instead?
 
there is no 2.8 zoom lens especially for APSC, only for FF (g lenses).
If you want native zoom there are 2 APSC lenses, 16-70 f/4 OSS and 18-105 f/4 OSS (i have the 18-105 and i am very happy with it).
