Thanks for sharing the observation, Aaron. Nice footage too. I noticed that initially they were keeping an eye on the Anafi! There was only a few minutes elapsed between the first & second parts of this video. They were very quick to settle in for a snooze.
There's a weird anomaly that occurs at 0:48 where the image is disproportionately distorted. That's in the footage & is the first time I have ever seen it happen with the Anafi. It looks like she gets buffeted by a gust of wind & is thrown off-course slightly at that moment, so it could possibly be the image sensor's yaw stabilisation kicking in weirdly. Maybe?
