Sensitivity (ISO Equivalency)
Photographs taken at slow shutter speeds are prone to blurring. If sensitiv-
ity is raised above the default value of ISO 200 equivalent, the same expo-
sure can be achieved at faster shutter speeds, preventing blur. Sensitivity
can be set to values between ISO 200 and ISO 1600 in steps of 1 EV.
Controls used:
➤ Shooting menu ➤ ISO
The ISO Button
If the monitor is off, sensitivity can be set by press-
ing the
(ISO) button and rotating the command
dial until the desired value is displayed in the control
panel.
Sensitivity
“Sensitivity” is the digital equivalent of fi lm speed. The higher the sensitivity, the
less light needed to make an exposure, allowing higher shutter speeds or smaller
apertures. Just as higher speed fi lms tend to be “grainy,” pictures taken at high
sensitivities are prone to mottling.
