25600:
You can reduce image blurring in dark locations or with moving subjects by increasing the ISO sensitivity
(select a larger number).
Note
[ISO AUTO] is selected when using the following functions:
[Intelligent Auto]
[Superior Auto]
[Scene Selection]
[Sweep Panorama]
When [ISO] is set to a value lower than ISO 100, the range for recordable subject brightness
(dynamic range) may decrease.
The higher the ISO value, the more noise will appear on the images.
When shooting movies, ISO values between ISO 100 and ISO 12800 are available. If the ISO value
is set to a value smaller than ISO 100, the setting is automatically switched to ISO 100. When you
finish recording the movie, the ISO value returns to the original setting.
When you use [Multi Frame NR], it takes some time for the product to perform the overlay processing
of images.
Hint
You can change the automatically set ISO sensitivity range for the [ISO AUTO] mode. Select [ISO
AUTO], press the right side of the multi-selector, and set the desired values for [ISO AUTO Maximum]
and [ISO AUTO Minimum]. The values for [ISO AUTO Maximum] and [ISO AUTO Minimum] are also
applied when shooting in [ISO AUTO] mode under [Multi Frame NR].
