.Sensitivity
Adjust the camera's sensitivity to light.
Sensitivity can be set by lifting and rotating the sensitivity dial.
Sensitivity
| 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 64 to 51200. This range includes “extended” values of 64 to 100, 25600, and 51200. Note that “extended” values may reduce dynamic range or increase mottling. |
| 125–12800 | 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.
Options
| Item | Options |
|---|---|
| DEFAULT SENSITIVITY | 125–12800 |
| MAX. SENSITIVITY | 400–12800 |
| MIN. SHUTTER SPEED | 1/2000–30 SEC, AUTO |
Default
| Item | AUTO1 | AUTO2 | AUTO3 |
|---|---|---|---|
| DEFAULT SENSITIVITY | 125 | ||
| MAX. SENSITIVITY | 800 | 3200 | 12800 |
| 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 choose the minimum shutter speed automatically. The minimum shutter speed is not affected by the option selected for image stabilization.
