Noise is more likely at higher sensitivities. Use the High ISO NR option
in the shooting menu to reduce noise (see page 259). 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, 0 281).
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 58-900,58-800,58-600, and 58-400
flash units), possibly
preventing the camera from selecting slow shutter B
speeds.
