Advanced Camera Settings - The Shooting Menu Fixed Aperture I This option keeps the aperture from shifting when zooming. This function is available only when the dial mode is set to E. J Off (default setting) I On Aperture changes with the zoom position. Aperture is kept as close as possible to the f/-number selected by you or the camera. To prevent the selected f/-number from exceeding the exposure range at the new zoom position, select an aperture from f/5 to f/7.3. Noise Reduction o At slow shutter speeds, "noise" in the form of randomly-spaced, brightly-colored pixels may appear in pictures, particularly in shadowy areas. When you take pictures under low levels of light, this option reduces noise. p Off (default setting) Turns Noise reduction off. o On Noise reduction takes effect at slow shutter speeds which "cause" noise. When Noise reduction is on, it takes longer to store pictures in the internal memory or on the memory card. Note on Noise Reduction When using Continuous mode (P.80) or when AUTO BRACKETING (P.83) is set to Auto bracketing or WB bracketing, Noise reduction (P.88) has no effect even if set to On. 88
