Re: 5DMKII base ISO

I found the base ISO is 160, not 200, and I get better noise behavior when I shoot at multiples of 160...

50, 100, and 125 straight, and 200 and 250 with HTP, are "base ISO" in the sense that they use the camera's smallest gain, all the same gain, just different logistics.

160 has more "footroom" than 100, but that is only because it is borrowed from the headroom. It's just the ISO 200 setting, labeled and exposed for 160.
