Thanks Ty Pilot. I do take a somewhat sceptical view of blogger comparisons since there's no way of knowing whether any coin changed hands. But the comparison I referred to was this one - which allegedly shows footage from the DJI 4k/12MP camera:
It may well be that the Typhoon wasn't properly set up or that the Phantom footage was enhanced in post (if so, it needed more work on colour balance and saturation in my view) but, at face value and imho, the Phantom video focus looks much superior - especially in the sequence starting at 1m22s. Which is why I'm hoping that the current Typhoon models/camera/lens and firmware are better than they were then. If not, I will live with it…but I might just wait for the next Yuneec announcement in case it makes me jump off a bridge.
