When shooting with a digital camera, image noise (image roughness 

or unevenness) becomes noticeable in the following situations. 

• when shooting with a high sensitivity setting

• when shooting with long exposures

• when the temperature of the CMOS sensor is high

You can reduce image noise by using Noise Reduction.

Reduces noise at high ISO sensitivity settings. 

1

Select [High-ISO NR] in the [A Rec. Mode 3] menu, and press 

the four-way controller (5). 

The [High-ISO NR] screen appears. 

2

Press the four-way controller (5), 

and use the four-way controller 

(23) to select a setting. 

Reducing the Image Noise (Noise Reduction)

Pictures cannot be taken while the camera is performing a noise reduction 

process. In particular, if you use [Slow Shutter Speed NR], it may take more 

time to process.

High-ISO NR

Auto

Applies Noise Reduction at optimally calculated 

levels throughout ISO range. (default setting)

Low/Medium/High

Applies Noise Reduction at constant chosen level 

throughout ISO range. 

Custom

Applies Noise Reduction at user-defined levels for 

each ISO setting. 

Off

Does not apply Noise Reduction at any ISO setting.
