A The ISO Sensitivity Menu
ISO sensitivity can also be adjusted using the
ISO sensitivity option in the shooting menu
(0 253).
A ISO Sensitivity Settings
The settings available depend on the option selected for Custom
Setting b1 (ISO sensitivity step value, 0 270).
A Hi 0.3–Hi 1
The settings Hi 0.3 through Hi 1 correspond to ISO sensitivities 0.3–1 EV
over ISO 3200 (ISO 4000–6400 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.

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