Adjust the camera’s sensitivity to light.
Press the sensitivity dial lock release, rotate the dial to the desired setting, and press the release again to lock the dial in place.
|Sensitivity is automatically adjusted in response to shooting conditions according to option chosen for [SHOOTING SETTING] > [ISO AUTO SETTING]. Choose from [AUTO1], [AUTO2], and [AUTO3].|
|Adjust sensitivity manually. Selected value is shown in display.|
|Choose for special situations. Note that mottling may appear in pictures taken at [H], while [L] reduces dynamic range.|
Use [BUTTON/DIAL SETTING] > [ISO DIAL SETTING (H)] to choose the sensitivity assigned to the [H] position.
Use [BUTTON/DIAL SETTING] > [ISO DIAL SETTING (L)] to choose the sensitivity assigned to the [L] position.
If [COMMAND] is selected for [BUTTON/DIAL SETTING] > [ISO DIAL SETTING (A)], sensitivity can also be adjusted by setting sensitivity to [A] and rotating the front command dial.
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.
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 [AUTO1], [AUTO2], and [AUTO3] can be stored separately.
|[MIN. SHUTTER SPEED]||1⁄500–1/4 SEC, AUTO||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]. If [AUTO] is selected for [MIN. SHUTTER SPEED], the camera will automatically choose a minimum shutter speed approximately equal to the inverse of the lens’ focal length, in seconds (for example, if the lens has a focal length of 50 mm, the camera will choose a minimum shutter speed in the neighborhood of 1⁄50 s). The minimum shutter speed is not affected by the option selected for image stabilization.
