I was curious as to how much gain is being applied at each ISO on the RX10-II.
I shot some test footage with the RX10-II and went up the ISO ladder and stopped for a few seconds on each setting. I then took the card and placed it in my AX100 and played back the file. As you might know, the AX100 will display the gain amount data in real time as you play back the file .
This is gain metadata inside the .mp4 file so I suspect it should be accurate. Here are the results:
0db - 200 ISO
3db - 250 ISO
3db - 320 ISO
6db = 400 ISO
9db = 500 ISO
9bd = 640 ISO
12db = 800 ISO
15db = 1,000 ISO
15db = 1,250 ISO
18db = 1,600 ISO
21db = 2,000 ISO
21db = 2,500 ISO
24db = 3,200 ISO
27db = 4,000 ISO
27db = 5,000 ISO
30db = 6,400 ISO
33db = 8,000 ISO
33db = 10,000 ISO
36db = 12,800 ISO
I don't have my original RX10 anymore. I sold it a few months back. So, I can't compare them side by side. However, just looking at these RX10-II files, it seems that either this new sensor is a bit cleaner or the noise reduction has been modified? (maybe?) At least compared to my memory of the original RX10 but it's hard to say for sure unless you test them both together.
I can do some side by sides with the AX100 which I believe uses the same sensor as the original RX10.
Anybody have both RX10's (original and new?)
