Pentax K-r iso issue


I'm an owner of a Pentax K-r and my ISO is stucking on a range of 400 to 12800.

I want to set it to 100 to 25600, but i can't find the option in the menu bars. :/

Need help! D:

1. Disable the expanded dynamic range option via the info screen/main menu
2. Enable the expanded ISO range option in the custom settings menu

Ensure that the highlight and shadow correction are both turned off and you set the auto ISO to 100-25600. It is likely that both these settings are on and by how they work, they take a stop of ISO from both ends to allow for the correction. Also ensure that ISO expansion is set to on in the menu setting. This enables you to go down to 100 and up to 25600
