What happens to Big Whites when Mirrorless Takes Over?

The good thing about the Big Whites is that their colour keeps things cool, which will help a lot with the A9...
It's almost like Canon saw the A9 coming..!

I don't think the USM or STM lens motor has anything to do either reading or processing AF information, be it on sensor or off sensor. That is done in the camera and the lens motor doesn't have anything to do with it. All the lens motor does is adjust the lens in response to signals sent by the camera. So, I don't see how or why a lens motor would respond differently depending on whether the AF is off sensor (phase detect) AF on on sensor (contrast detection).

I said it on some other thread here a couple of weeks ago - I swear we could watch it happen over the last few years.
1) STM is launched and described as "great for video"
2) DPAF is launched and described as "great for video"
3) DPAF cameras are bundled with STM lenses with much ballyhooing over video
4) people assume that DPAF and STM must go together and USM doesn't work as well with DPAF
That last bit was never stated, but is a tempting conclusion, and once people starting saying it, it became entrenched as an assumption that low-information people accepted without question.

not true at all.
STM was better for Hybrid AF sensors that used PDAF points and CDAF to focus. CDAF required STM for relatively smooth focus because it would focus in short iterative steps.
with DPAF sensors they are phase detect only, which means that it really doesn't matter anymore. which is why any modern lens focuses just fine in liveview mode on a 5DIV, 1DX II, M5,etc.
with further maturing of DPAF sensors and the related DIGIC's to drive them, STM simply just becomes a cost saving approach. but with linear USM now, it could be that STM gets phased out all together.

"Normal folks" don't buy Great Whites even if they have a lot of money. Only complete, kookoo bananas, obsessive-compulsive, all-in photographers willing to spend hours chasing a few great shots while dragging around tons of gear through tick infested wilds...
In other words, shutter bugs on steroids.

Interesting. New to me. Curious and have Canon 300mm f/2.8 IS L and 100-400 IS L II. How does this work (not the iphone-thingy that's obvious, but the "scope" parts)?

Digiscoping is about using a phone (or originally, a P&S) on the back of a telescope, not a camera lens.
It was a very limited, cobbled-together way of getting more focal length onto a bird, before DSLRs and longer lenses started to become ubiquitous - no metering, no meaningful shutter-speed control, no AF, but it was enough to give the user at least a chance of an image that wouldn't be achievable with a P&S alone.
Digibinning is a similar idea, but putting the phone or camera behind the eyepiece of a pair of binoculars.
