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 (aCOMMAND 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).
