[QUOTE="Vincent, post: 347266, member: 15675"] From an other thread again: First remark video is not stills (so video does not deliver a lot of info on usable stills). But it seems to be in line with the expectations from the tests, it is mainly between 16000 ISO and 51200 ISO that the A7s outperforms the D4s or Df. (I still doubt that you get a lot of useful things but some seem to be OK for 80000 and exceptionally 102400 ISO). However: 1) that is only doing a bit more then doubling your shutter speed (or 5* for the very optimistic; = 1 to 2.5 stops gain) 2) I have been scanning the pictures taken with the A7s, I'm convinced less then 5% is taken above ISO16000. Maybe that is habit, something like I always go out with a tripod also with the A7s, so why do ultra high ISO? It seems more to me this is normal, but it also means you will not have a lot less shots having another high ISO camera. [/QUOTE]
