AISO Sensitivity Settings

The settings available depend on the option selected for Custom Setting b1 (ISO sensitivity step value, pg. 292).

ISO sensitivity settings available

Lo 1, Lo 0.7, Lo 0.3, 200, 250, 320, 400, 500, 640, 800, 1000, 1250, 1600, 2000, 2500, 3200, 4000, 5000, 6400, Hi 0.3, Hi 0.7, Hi 1, Hi 2

Lo 1, Lo 0.5, 200, 280, 400, 560, 800, 1100,

1600, 2200, 3200, 4500, 6400, Hi 0.5, Hi 1,

Hi 2

Lo 1, 200, 400, 800, 1600, 3200, 6400, Hi 1, Hi 2

*If possible, the current ISO sensitivity setting is maintained when the S 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.

AHi 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.

ALo 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 lower than normal; in most cases, ISO sensitivities of ISO 200 or above are recommended.
