7Ds native ISO is 160 right? You get the cleanest images if you shoot at 160, 320, 640, 1250 etc.

Is the 60D the same? I assume it is.

Also, if the ISO's in between are being pushed or pulled via software. Then would the best ISO be the one just under native? If you overexpose a little and pull it back in PP you'll see less noise. So are the ideal ISO settings really a 1/3 stop below the native ISOs...125, 250, 500, 1000 etc.?

I just had this thought, but I haven't been able to test it. I honestly don't think I've ever used ISO 500 or 1000. I've been using 640 and 800 almost exclusively.

Way I'd always understood it was that the native iso's were 100,200, etc. That the 160/320/etc were pulled, and the 125/250/etc were pushed.

That was the reason for 160 looking better than 100, that it was actually 200, cut by a third in software, and why 125 looked worse than 200, because it was 100 pushed in software.

Using the 160/320/etc (if all of this is true of course) will mean a slight reduction in dynamic range since it's artificially been fiddled with.
