U

Choose whether to reduce noise in pictures taken at slow shutter 
speeds.

Photographs taken at high ISO sensitivities can be processed to 
reduce “noise.”

Photographs taken at shutter 
speeds slower than 8s are 
processed to reduce noise. 
While photographs are being 
processed, “l m” will blink 
in the shutter speed/aperture 
displays for a period of time 
approximately equal to the 
current shutter speed.  In 
continuous release mode, frame 
rates will slow and the capacity of the memory buffer will 
drop.  Photographs can not be taken until processing is 
complete and “l m” has cleared from the displays. 
Noise reduction will not be performed if the camera is 
turned off before processing is complete.

Off (default) Long exposure noise reduction off.

S High

Noise reduction is performed at ISO sensitivities of 
ISO 500 and higher.  While photographs are being 
processed, the capacity of the memory buffer will drop. 
Choose the amount of noise reduction performed from 
[High], [Normal], and [Low].

T

Normal
(default)

U Low

Noise reduction is only performed at sensitivities of 
Hi 0.3 and higher.  The amount of noise reduction is less 
than the amount performed when [Low] is selected for 
[High ISO NR].
