I’m shooting a themepark (z8 advice)

[gethin]

Which is out of my jobbing comfort zone.  I’ve done it before but 10+ years ago and honestly kinda fluked it: like manually focus pulling on people zooming down slides.

They want stills and video.  There’s a bunch of things I need to test but thought I’d canvas opinion

I have Nikon ed 300mm f2.8 and vrii 70-200 f2.8. Using the zoom previously I found the autofocus a bit shit - especially with subject approaching camera, and that was with stills.  I’m assuming this is because it’s not native z mount (I have ftz1). Do I have a hope in hell of either of these handling video af with fast moving subjects?  Any advice on modes would be appreciated.  
 

Nraw:  Just seen premiere beta supports nraw.  I’m thinking of shooting raw and extracting stills from the 8k files.  Is this a terrible idea?  I have done this with 8k h265 but the stills are kinda nasty. (I’ll shoot high shutter speed/small shutter angle). I have no idea of raw workflow either.  

was planning on handing out insta 360 to people too to get some action and pov stuff but this footage looks super video-y. Are there any action cams that might cut better with z8?
