This function reduces the noise that is generated duringlong exposures.[Auto]: Noise reduction is only performed at slow shutterspeeds.[On]: Noise reduction is performed with every shot.[Off]: Noise reduction off.• Noise reduction requires about twice the time needed torecord the image.• Noise reduction turns off automatically during sequentialshooting.• This function may not work effectively with some shootingconditions or subjects.27Noise Filter Choose the amount of noise reduction performed at highISO sensitivities. —ISO Set ISO sensitivity. This is the same as the live controlsetting. 56ISO Step Select the increments available for choosing ISO sensitivity. —ISO-Auto Set Choose the upper limit and default value used for ISOsensitivity when [Auto] is selected for ISO.[High Limit]: Choose the upper limit for auto ISO sensitivityselection.[Default]: Choose the default value for auto ISO sensitivityselection.—ISO-Auto Choose the shooting modes in which [Auto] ISO sensitivityis available.[P/A/S]: Auto ISO sensitivity selection is available in allmodes except M. ISO sensitivity is fixed at ISO200 in modeM.[All]: Auto ISO sensitivity selection is available in all modes.—Metering Choose a metering mode according to the scene. 54AEL Metering Choose the metering method used for AE lock (P. 79). [Auto]:Use the currently selected metering method. —BULB/TIME Timer Choose the maximum exposure for bulb and timephotography. —Live BULB Choose the display interval during shooting. Somerestrictions apply. The frequency drops at high ISOsensitivities. Choose [Off] to disable the display. Tap themonitor or press the shutter button halfway to refresh thedisplay.—Live TIME —Anti-Shock z Choose the delay between the shutter button beingpressed and the shutter being released. This diminishescamera shake caused by vibrations. This feature isuseful in situations such as microscope photography andastrophotography.
