Adjust the camera’s sensitivity to light.
Sensitivity can be set by lifting and rotating the sensitivity dial.
|[A](auto)||Sensitivity is automatically adjusted in response to shooting conditions according to option chosen for A[SHOOTING 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.|
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 A[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 [AUTO1], [AUTO2], and [AUTO3] can be stored separately; the defaults are shown below.
|[MIN. SHUTTER SPEED]||1/500-1/4 SEC||1/60 SEC|
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].
