Option Description



Sensitivity is automatically adjusted in response to shooting conditions according to option chosen for [SHOOTING SETTING] > [ISO AUTO SETTING]. Choose from [AUTO 1], [AUTO 2], and [AUTO 3].



Sensitivity can be set by rotating the front command dial. Choose from values of from 100 to 12800 or select “extended” values of ISO 50 or of ISO 25600 or higher.



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 sensitivitie.

Auto Sensitivity (A)

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]
[MAX. SENSITIVITY] 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].
