slow motion test, gopro and Sony fs7 150 fps 1/400 (and later also dji3, sony A6500). And highlight/backlight white. (the tables in laboratory are really purple.)
Thanks Doug, yes you are right. And since it is 1920 x 1080 already cropping is no option. Happily I had another camera running in 4K, but also wide as it was unmanned (a A6500 that I rented). And I am happy it was in focus, but I know what you mean.
