Select On to reduce noise (randomly-spaced bright pixels, lines, or fog), particularly in photographs taken at high ISO sensitivities or shutter speeds slower than 8 s. The time required for processing is roughly equal to the current shutter speed; during processing, “l m” will blink in the viewfinder and photographs can not be taken. 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 high ISO sensitivities; the amount of noise reduction is less than that performed when On is selected.
If On is selected and lighting is poor when photographs are | AF-assist illuminator |

dDynamic-area AF, or f3D-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.
