Interesting.
Joze, did you squeeze the poor Sigma? Sat on it? Stood on it, you nasty boy? I didn't, but I was going to think it could be a low tide of the drop's inner structure, caused by one of the moons of Jupiter. As explanation not much more fantastically than squeezing a glass lens.
I saw the effect only on the outer sides of the fountain. Therefore my guess about speed. It turned out, one of the 1/8000 shots showed the effect, too, just much less than the longer shuttertimes. Also, the longer the FL, the more likely those shapes become visible.
