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].
