Right so the starlings have started coming in over the reedbed near me, couple of thousand most nights maybe more, and every year I go down and every year I come home with mush, the light goes so fast that by the time they're doing the good shapes I'm at ISO 12800 on the R7 and its just a grey smudge with black dots in it, or I go slow to keep ISO down and its blurry dots
the 100-400 is f/8 at the long end which doesnt help tbf, I usually end up nearer the wide end anyway because the flock is huge
what are people doing, am I just there too late, or is it accept the noise and denoise it, or go the other way and do a proper slow blur on purpose
