ISO Sensitivity

Select ISO sensitivity from the Quick settings display to adjust the setting (A 48). Photographs taken at slow shutter speeds are prone to blurring. If ISO sensitivity is raised above the base setting of ISO 100, the same exposures can be achieved at faster shutter speeds, preventing blur. ISO sensitivity can be set to values between ISO 100 and ISO 1600 in steps of 1EV, with a further high sensitivity setting of Hi 1 available for an ISO equivalent of approx. 3200.

Digital Vari-Program modes also offer an Auto setting that allows the camera to automatically raise sensitivity when lighting is poor or lower sensitivity when lighting is bright.

BHigh Sensitivity Setting of Hi 1

Photographs taken at a sensitivity setting of Hi 1 are prone to be grainy and exhibit mottling.

CISO Sensitivity Setting

Rotating the mode dial from a, b, c, or dto a Digital Vari-Program mode automatically restores the default ISO sensitivity of Auto.

CISO Auto

Use Custom Setting 10 (ISO auto; A 111) to enable automatic ISO sensitivity control in a, b, c, and dmodes. When Hi 1 is selected, automatic ISO sensitivity control is disabled.

CMore Information

For more information about reduce noise at high sensitivities, see Noise reduction in the shooting menu (A 108).

DSensitivity

ISO sensitivity is the digital equivalent of film speed. The higher the ISO sensitivity, the less light needed to make an exposure, allowing higher shutter speeds or smaller apertures. Just as higher speed films tend to be “grainy,” photographs taken at high ISO sensitivities are prone to mottling.
