Changing Shooting Settings
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.
B High Sensitivity Setting of Hi 1
Photographs taken at a sensitivity setting of Hi 1 are prone to be grainy and exhibit mottling.
C ISO Sensitivity Setting
Rotating the mode dial from a, b, c, or d to a Digital Vari-Program mode automatically restores
the default ISO sensitivity of Auto.
C ISO Auto
Use Custom Setting 10 (ISO auto; A 111) to enable automatic ISO sensitivity control in a, b, c,
and d modes. When Hi 1 is selected, automatic ISO sensitivity control is disabled.
C More Information
For more information about reduce noise at high sensitivities, see Noise reduction in the shooting
menu (A 108).
D Sensitivity
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.
E ISO Sensitivity
ISO sensitivity can also be set using the ISO sensitivity option in the shooting menu (A 100).
F 11 — F/G Button (A 112)
ISO sensitivity can also be set using the command dial.
