Many thanks for all the replies and videos, much appreciated. I don't think it changes my view though. I absolutely get the geomapping and search/rescue thing, no debate.
And if all you're interested in is general landscape views with an acceptable angle of view, then again no argument.
I don't buy the issue of it solving the problems of jerky movements; adjust your stick movement, use tripod or spotlight or just edit them out. The "case closed" video didn't persuade me either. It was only two clips transitioned and could easily have been done with spotlight and recreating your height and distance for the second run, although I am assuming/guessing that you can store and repeat missions? If so, that would make for a much longer,more interesting and wider ranging season to season comparison video which could be great, but that's a very specific case I think.
Broadly all that puts me off is the lack of accurate control over camera position, field of view etc.. which are critical to a photographer.
One question out of interest, what happens with a drone that needs focussing like the Pro I believe does? Do you just have to prefocus before it sets off?
