Anyway, i did another quick test aka rush job, the same settings like previous, A7S fitted with 55mm f1.8, A6000 fitted with 35mm f2.8 aka FF equivalent 52mm. I set the shutter speed to 1/60, aperture at 2.8, ISO varies depends on comparison. Now for both cameras i set the HIGH ISO NR to LOW. And these are JPEGS OOC except for ISO6400 i brighten in post at 2 stops and ISO128000 brighten in post at 1 stop.
A6000 ISO6400, brighten in post 2 stops.
A7S ISO6400 brighten in post 2 stops
A6000 ISO128000, brighten in post 1 stop
A7S ISO128000 brighten in post 1 stop
A6000 ISO256000 OOC Untouched
A7S ISO256000 OOC Untouched
A7S still comes out better as expected. I like the grain structure of the A7S. Both cameras have color noise but its worst on the A6000 and the A6000 is smudgy as well.
I blog more when i have time now i gotta go. duty calls!
