A ISO Sensitivity Settings
The settings available depend on the option selected for Custom Setting
b1 (ISO sensitivity step value, pg. 292).
A Hi 0.3–Hi 2
The settings Hi 0.3 through Hi 2 correspond to ISO sensitivities 0.3–2 EV
over ISO 6400 (ISO 8000–25600 equivalent). Pictures taken at these
settings are more likely to be subject to noise and color distortion.
A Lo 0.3–Lo 1
The settings Lo 0.3 through Lo 1 correspond to ISO sensitivities 0.3–1 EV
below ISO 200 (ISO 160–100 equivalent).
Use for larger apertures when
lighting is bright. Contrast is slightly higher than normal; in most cases,
ISO sensitivities of ISO 200 or above are recommended.

*If possible, the current ISO sensitivity setting is maintained when the
step value is changed. If the current ISO sensitivity setting is not
available at the new step value, ISO sensitivity will be rounded up to the
nearest available setting.
