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 sensitivitie.
Use SHOOTING 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 AUTO 1, AUTO 2, and AUTO 3 can be stored separately; the defaults are shown below.
| Option | Default | ||
|---|---|---|---|
| AUTO 1 | AUTO 2 | AUTO 3 | |
| DEFAULT SENSITIVITY | 100 | ||
| MAX. SENSITIVITY | 800 | 1600 | 3200 |
| MIN. SHUTTER SPEED | 1/60 s | ||
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.
