Even more impressive, on this theme, I saw a friend's pano he took from a Mavic Pro (1) at night of a bridge with it's lights. It was obviously a reasonable long exposure of up to 15 seconds from memory as the photo was really well exposed and pin sharp. As you say, to take a shot like that would have taken a very steady tripod, yet this drone was hovering in the breeze, at night and doing a long time exposure. Is that insane or what???
