Setting ISO
Sensitivity to light is expressed by the ISO number (recommended
exposure index). The larger the number, the higher the sensitivity.
Notes
• The recordable range of the brightness of a subject (dynamic range) is slightly
narrower for areas where ISO is less than 100.
• When the exposure mode is set to Auto Mode, Sweep Panorama, or Scene Selection,
ISO is fixed to [AUTO] and you cannot select other ISO numbers.
• When the exposure mode is set to P/A/S/M and ISO is set to [AUTO], ISO is
automatically set between ISO 100 and ISO 6400.
To change the automatic adjustment range in [AUTO]
When [AUTO] is selected, press B, select [ISO AUTO Maximum] or [ISO
AUTO Minimum], then select the desired range.
The camera automatically shoots multiple images continuously, combines
the images, reduces the noise, and records 1 image. In multi frame noise

• The larger the number, the higher the noise level.
• If you want to select [Multi Frame Noise Reduct.], display the setup screen
with B, and select the desired value with v/V.
• The number changes in increments of 1/3 of a step using the rear control
dial as with the multi-selector, and it changes in increments of 1 step using
the front control dial.
