If On is selected, photographs taken at shutter speeds slower
than 8 s or at ISO sensitivities over ISO 400 will be processed to
reduce noise.
The time required for processing is roughly equal
to the current shutter speed; during processing, “lm” will
blink in the viewfinder and photographs can not be taken.
In
continuous release mode, frame rates will slow and the capacity
of the memory buffer will drop.
Noise reduction will not be
performed if the camera is turned off before processing is
complete.
If Off is selected, noise reduction will only be performed at ISO sensitivities over ISO
800; the amount of noise reduction is less than that performed when On is selected,
and does not apply to noise caused by slow shutter speeds.
If On is selected and lighting is poor, the built-in AF-assist
illuminator (0 43) will light to assist the focus operation in
single-servo AF (AF-S selected for focus mode, or single-servo AF
selected in AF-A focus mode) when e Auto-area is selected for
AF-area mode or when c Single point, d Dynamic area, or
f 3D-tracking (11 points) is selected and the center focus
point is used.
If Off is selected, the AF-assist illuminator will not
light to assist the focus operation.
The camera may not be able
to focus using autofocus when lighting is poor.
