Adjust the camera’s sensitivity to light.

Sensitivity can be set by lifting and rotating the sensitivity dial.


Option Description
A(auto) Sensitivity is automatically adjusted in response to shooting conditions according to option chosen for ASHOOTING SETTING > ISO AUTO SETTING. Choose from AUTO1, AUTO2, and AUTO3.
C(command) Rotate the front command dial to choose from values of from 80 to 51200. This range includes “extended” values of 80 to 125, 25600, and 51200. Note that “extended” values may reduce dynamic range or increase mottling.
160-12800 Adjust sensitivity manually. Selected value is shown in display.

Adjusting Sensitivity

High values can be used to reduce blur when lighting is poor, while lower values allow slower shutter speeds or wider apertures in bright light; note, however, that mottling may appear in pictures taken at high sensitivities.

Auto Sensitivity (A)

Use ASHOOTING SETTING > ISO AUTO SETTING to choose the base sensitivity, maximum sensitivity, and minimum shutter speed for the A position on the sensitivity dial. Settings for AUTO1, AUTO2, and AUTO3 can be stored separately; the defaults are shown below.

Item Options Default
MAX. SENSITIVITY 400-12800 800 1600 3200

The camera automatically chooses a sensitivity between the default and maximum values; sensitivity is only raised above the default value if the shutter speed required for optimal exposure would be slower than the value selected for MIN. SHUTTER SPEED.

If the value selected for DEFAULT SENSITIVITY is higher than that selected for MAX. SENSITIVITY, DEFAULT SENSITIVITY will be set to the value selected for MAX. SENSITIVITY.

The camera may select shutter speeds slower than MIN. SHUTTER SPEED if pictures would still be underexposed at the value selected for MAX. SENSITIVITY.
