Unable to go to ISO 100 on my Pentax k-7.

**Tonytee** · 01-06-2022, 03:13 AM

For some reason, I am unable to set ISO 100 on my K-7. I can go higher from ISO 200, but cannot back down to ISO 100.

Thanks very much for all assistance.

If it's anything like the K5, which I think it is, you set the range of allowable ISO in the ISO AUTO Setting in the Camera 3 Menu.

Update: It's in the Camera Mode 1 menu on the K7. However, note that if you have set Highlight Correction to On in D-Range Setting (Camera 1 menu), the minimum sensitivity is ISO 200. That is likely your issue.

Hello Paul,

Thanks a million for the help. The D-Range was the issue. Now I can remove the noose from around my neck. Phew!! That was close.
