Pentax k-5 iso issue

Hi guys!

I am relatively new to Pentax. Recently I noticed that my k-5 does not go lower than iso 200 with normal iso setting and 160 in extended sensitivity setting.
Maybe this is just a simple setting but I cannot find the solution.

Any advice is welcome.

Thanks a lot.

no, just press the "info" button and desactivate the higlight / shadow compensation.

Turn off Highlight and/or Shadow Correction in D-Range Setting.

It goes to 100 or 80 on extended sensitivity setting. You've got either the highlight or shadow correction set (record menu 3 Dynamic Range). When set the minimum ISO goes to 200 and 160 respectively. Turn off both of those and your ISO will behave as expected.

Thank you very much guys for responding this fast. The highlight correction was the "problem".
Thanks again.
