AAuto ISO Sensitivity Control

Noise is more likely at higher sensitivities. Use the High ISO NR option in the shooting menu to reduce noise (see page 205). When a flash is used, the value selected for Minimum shutter speed is ignored in favor of the option selected for Custom Setting e1 (Flash sync speed, 0 222). Note that ISO sensitivity may be raised automatically when auto ISO sensitivity control is used in combination with slow sync flash modes (available with the built-in flash and SB-900, SB-800, SB-700, SB-600, and SB-400 flash units), possibly preventing the camera from selecting slow shutter speeds.
