Sensitivity is automatically adjusted in response to shooting conditions according to combination of standard and maximum sensitivity and minimum shutter speed chosen for ASHOOTING SETTING > ISO. Choose from AUTO1, AUTO2, and AUTO3 (aAUTO). |
| 80–12800 | Adjust sensitivity manually. Selected value is shown in display. |
| L (40) H (25600) H (51200) H (102400) |
Choose for special situations. Note that mottling may appear in pictures taken at H, while L reduces dynamic range. |
Sensitivity is not reset when the camera is turned off.
If desired, you can use DBUTTON/DIAL SETTING > COMMAND DIAL SETTING to configure the camera so that ISO sensitivity can be adjusted using the front or rear command dial.
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
Choose the base sensitivity, maximum sensitivity, and minimum shutter speed for AUTO1, AUTO2, and AUTO3.
Options
| Item | Options |

Default
| Item | AUTO1 | AUTO2 | AUTO3 |
|---|---|---|---|
| DEFAULT SENSITIVITY | 80 | ||
| MAX. SENSITIVITY | 800 | 1600 | 3200 |
| MIN. SHUTTER SPEED | AUTO | ||
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.
If AUTO is selected for MIN. SHUTTER SPEED, the camera will automatically adjust the minimum shutter speed according to the focal length of the lens (the setting remains the same whether image stabilization is on or off).
