Minimum ISO

My K-5 IIs arrived yesterday and I'm getting acquainted with it but I've run across one thing so far that I haven't been able to figure out. When the camera is in Auto ISO mode, I cannot set the minimum ISO below 200; I would prefer it at 100. Is this normal or am I missing a setting somewhere?

you'll need to select expanded sensitivity from the menu

got to menu, C, and point 3 should probably say extended sensitivity (my camera is in Dutch so I don't know the exact translation). If you turn that on you can go as low as ISO 80.

Did that and now I can get down to ISO 160 but it refuses to move below that. I tried a couple of different lenses and it's the same with both.

OK. I probably should have done this as soon as I got since it was a used camera: I just did a reset to defaults and it's working as expected now. Something in some obscure menu was probably set. Now I'm starting with a clean slate. Thanks for the quick responses.

If i'm correct turning on highlight and shadow compensation changes the min/max ISO values. Try turning these functions off.

That may have been what it was. Those were turned on. At any rate, it's working good now. Thanks.

Highlight protection, if on, doubles minimum ISO - so 200 or 160 with expanded ISO on
