K5ii will not go below 200iso

OK, I must be doing something silly. For the last two days I can not figure out why I can not set the ISO lower than 200 on my K5ii. I went in the menu to ISO AUTO Setting, and it is at 200-3200. It will not let me go lower than 200, and ofcourse I cannot go below 200 when hitting the ISO button either. I've been using it in M mode, don't know what gives?

You probably have highlight or shadow correction on. Those settings will limt the ISO range.

Shut off highlight correction, go to the auto ISO and use the two scroll wheels to set maximum and minimum ISO. Does it work?

I wonder why camera doesn't disable Highlight and shadow correction by default when RAW mode is selected.

Hiho!

Because it works also for RAW? At least that was my understandig. Am I wrong? Any link to read some more information would be much appreciated.

So long, Finster.

Highlight correction affects RAW - basically it underexposes by up to a stop and then adjusts the brightness in software so that the brightest highlights are nearly clipped (histogram shift). Shadow correction only acts when converting to JPEG in-camera, essentially it brightens the shadows somewhat.

....(histogram shift)
As far as I know, mathematically it's not a histogram "shift".

The left border of the histogram is shifted, the right border not.
To fit in the now smaller range, the histogram gets compressed.

If highlights are still clipped, you can combine it with (-EV) and shaddow correction.

All I can go by is what my K-7 does. Quick snaps (handheld so not 100% identical scene, but very close), RawDigger RAW histograms with (7313) and without (7314) highlight correction. This is what I always see.
