Mark III --- ISO selection --- can't shoot L-100 or 3200-H, even with C.Fn allows

C.Fn I: Exposure (3) = high iso H, low iso L ENABLED, but I can't select them when adjusting ISO. I can only select the native (200-3200) ISO. Is there another C.Fn that might interfere with this?

It was working before, I'm unsure what I did here...

Do you have highlight tone priority set?

Yes... interesting - why is it that tone priority nixes your high ISOs?

Also FWIW, the native ISO range on the 1D MKIII is 100 - 3200.

Because it can;t shift to the next highest or lowest ISO setting if your already at the max or minimum possible setting...
There's no more there there to move to.....
For it to work, it needs to go to the next level..

But highlight tone priority nixes iso 100...

Right, because that is the lowest NATIVE ISO. L (ISO 50) is not a NATIVE ISO.

A slight correction, here...

...This camera's native ISO range is the entire ISo100-3200 and ISo6400.

Per all my raw files archive, every ISO step (at least measured from ISO800), all the way to ISO6400 are pretty much and generated or derived from analog amplification. NO strange/crooked shadows-data in the bottom of the RAW files (no signs of "artificial" intelligence, that is).

Now, that the effective DR decreases by basically one (1) stop, going from ISo3200 to ISo6400, is another thing.

But rest assured that ISO6400 is not fabricated at a later digital stage, in the 1D3 (exactly same for 1DsMarkIII's ISO3200). Interestingly, the 5D MarkII that I got for inspection a few days ago, does fabricate ISo6400 and beyond, in the digital domain, indeed. (I did not measure/captured ISo4000 and ISo5000 frames, though).

By native we are referring to non-extended ISOs, no one said anything about being computer generated in camera.

Ah, understood!

...It is just that "h", in my world, simply means that the Turbo is about to spool up all the way to 40psi...
