ISO setting

I've just got a replacement K5 and away from home.
I can't get the camera to change to ISO 100 and don't have my manual with me.
I have the Pentax 16-50mm DA* lens
I can only get 200 ISO and above

Can anybody steer me in the right direction?

Try menu C3-1: Expanded Sensitivity, turn On.
To get ISO 80, be sure Highlight Correction (Under Rec.3 D-Range Setting) is also set to Off.

Link to manual is here.

Hmm I think you should go to the custom settings tab number 1 and there will be the option called 'Expanded Sensitivity'. Change to number 2.

Many thanks for quick reply - spot on on both counts
I hadn't realised D-range setting had this effect
And thanks for the link to the manual

Are you in Green mode? If so, ISO can't be changed - remains in Auto mode, so if you've set lower ISO limit to 200...

If you are in Green, change to another mode. Press and hold ISO button and change ISO with rear e-dial. Release both; ISO set.
