Noise Reduction G button ➜ C shooting menu Select On to reduce noise (bright spots, randomly-spaced bright pixels, lines, or fog). Noise reduction takes effect at all ISO sensitivities, but is most noticeable at higher values. The time required for processing at shutter speeds slower than about 1 s or when the camera's internal temperature is elevated and ISO sensitivity is high roughly doubles; during processing, "l m" will flash in the viewfinder and photographs can not be taken.

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.
