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.
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 AUTO1, AUTO2, and AUTO3 can be stored separately; the defaults are shown below.
|MIN. SHUTTER SPEED||1⁄500–1/4 SEC, AUTO||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 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.
