I put UK in heading because where I live distance and height are not relevant. Unlike North Americans with great distances as I have seen on this forum I live in an urban sprawl. Hence I set the height to 55m which for me is enough. I have adopted a routine where I set the exposure in Auto and then switch to manual so it does not change when I tilt down. Did a couple of short tests at 120 FPS and a panning/move test. Finished video showed no jerkiness. Video is untouched picture wise. But there is an ND4 filter on the H.
