Genuine question, since I'm not part of the Apple ecosystem and my smartphones tend to be from the low end of the range.

Even my humble one takes great pictures and video, but the touch-screen UI is really limiting. Whereas professional movie camera work has smooth pan/zoom work that, at least until now, was done with appropriate controls. Do professionals using a slab phone have external pan/tilt/zoom/focus rigs that they can plug in as an accessory, or do they have to do all that via the touchscreen UI?

If you watch the video, you can see that they have a big rig with like a gimbal and external controllers and screens. So it's not "just an iPhone" but it's also not a $50k+ pro camera body.

How do the external controllers interface with the third party camera app? How.much do these controllers cost?

I think a lot use separate apps. I had a gimbal that I used to use with an old iPhone with buttons to move the gimbal and direct the phone, but also with buttons to start/stop recording, and do other things without touching the phone itself. This gimbal was in the $300-$500 range.

Look at pretty much any one of the pictures in the article for your answer.

No professional camera, iPhone or not, isn't in a rig/harness/on a trolley etc. That's for pan/tilt/push in/pull out. For controlling camera settings/zoom/focus, the article says they are using Blackmagic Camera.
