yes about the 160 iso, but the best we have now is by 100's unfortunatly for video, but at least its not to far off from 160, it is very interesting however how 320 and 640 are cleaner then 100 being that there higher numbers but yet 300 and 600 are worse, intersting why this is like this for video, i will do some tests with my lightning at 160 and 320 on stills to see if this is the same on stills, in my line of work of photography i grew up learning the higher the iso the more the grain, very cool info about this video though, thanks for sharing 8]
