ISO 80. Where is it?

Not that I need it badly. But reading so much about it and being with K-5 only few weeks I am testing and learning my camera.
So where is the ISO 80. All I can see and access is ISO 100. Also manual does not say a word about ISO 80.

Go to your C menu, option 3. Expanded sensitivity ON. Will enable ISO 80-51200. It's also in the manual.

Yes! All I can get now is ISO 160 most of the modes.

Go to item 3 on the custom menu - expand sensitivity, select yes.

Turn off highlight correction in your D-range settings, otherwise you will only get ISO 160 as a minimum.

Sounds like you have Highlight Correction enabled in the D-Range Setting menu selected.

Sort of scary...I have had my K20D for almost three years and I am just now on page 12 of the manual....this might be a problem for me, you think? I may be here a lot asking questions, I was raised believing that real men don't need instructions or maps....any of you like that?
Best Regards!

What's the consensus on this? Would you rather have ISO 80 available, given plenty of light, of course, or highlight correction enabled?

I just LOVE low ISO, even in relatively low light, and don't much care about highlight correction I've mostly been shooting at 100-400. Haven't been down to 80 yet.

If there are some real bright highlights in the scene, highlight correction yields ~1 stop extra highlight range by flattening highlights on the tone curve. This has a subtle effect and can minimize clipping. OTOH, going from ISO 80 to 160 reduces overall DR by almost a full stop. So all things being pretty much equal it depends on whether you want to spend time in PP or have the camera do it.

Personally, I often enable highlight correction as a convenience.

I think I'd like to try shooting some sun-bursts with highlight correction enabled just to see what the results would be. Might be un-noticeable, might be un-desirable.

Straight into the sun, @ ISO 80, to give you an idea.
