When I work with my Minox subminiature cameras, ISO 100 is high ISO... I have the K10D set to Auto ISO with the range constrained to 100-400 most of the time. Differences in performance are near to invisible in that range. I go to 800, and very rarely to 1600, when I need more sensitivity. Those are high ISO settings, and I have the camera set to display the ISO warning when I'm there as they cost in dynamic range and image quality.
