Adjust the camera’s sensitivity to light.
Set sensitivity using A [SHOOTING SETTING] > [ISO].
|Sensitivity is automatically adjusted in response to shooting conditions. Different values for [DEFAULT SENSITIVITY], [MAX. SENSITIVITY], and [MIN. SHUTTER SPEED] can be chosen for each of [AUTO1], [AUTO2], and [AUTO3] (aAuto Sensitivity (A)).|
|160–12800||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.|
Sensitivity is not reset when the camera is turned off.
A B [MOVIE SETTING] > F [ISO] option is available in the movie shooting menu when F (movie) is selected for drive mode.
Sensitivity can be assigned to the front command dial using D [BUTTON/DIAL SETTING] > [COMMAND DIAL SETTING] (a[COMMAND DIAL SETTING]).
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)
Choose the base sensitivity, maximum sensitivity, and minimum shutter speed for [AUTO1], [AUTO2], and [AUTO3].
|[MIN. SHUTTER SPEED]||1/500–1/4 SEC, [AUTO]|
|[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 automatically choose a minimum shutter speed fast enough to prevent blur caused by camera shake or subject motion (the minimum shutter speed is not affected by the option selected for image stabilization).
