ISO (still image/movie)
Sensitivity to light is expressed by the ISO number (recommended exposure index). The larger the number, the higher
the sensitivity.
Menu item details
ISO AUTO:
Sets the ISO sensitivity automatically.
ISO 40 – ISO 409600:
Sets the ISO sensitivity manually. Selecting a larger number increases the ISO sensitivity.
Hint
You can change the range of ISO sensitivity that is set automatically in [ISO AUTO] mode. Select [ISO AUTO] and press the right
side of the control wheel, and set the desired values for [ISO AUTO Maximum] and [ISO AUTO Minimum].
The higher the ISO value, the more noise will appear on the images.
The available ISO settings will differ depending on whether you are shooting still images, shooting movies, or shooting slow-
motion/quick-motion movies.
When shooting movies, ISO values between 80 and 409600 are available. If the ISO value is set to a value smaller than 80, the
setting is automatically switched to 80. When you finish recording the movie, the ISO value returns to the original setting.
The available range for ISO sensitivity varies depending on the setting for [Gamma] under [
Picture Profile].
The available ISO sensitivity range changes when outputting RAW movies to another device connected via HDMI.
Note
[
ISO] is set to [ISO AUTO] in the following shooting modes:
[Intelligent Auto]
When the ISO sensitivity is set to a value lower than ISO 80, the range for recordable subject brightness (dynamic range) may
decrease.
When you select [ISO AUTO] with the shooting mode set to [P], [A], [S] or [M], the ISO sensitivity will be automatically adjusted
within the set range.
If you point the camera at an extremely strong light source while shooting images with a low ISO sensitivity, highlighted areas in
the images may be recorded as black areas.

You can also select MENU →

You can change the value by 1/3 EV steps by turning the front dial as well as by turning the control wheel. You
can change the value by 1 EV steps by turning the rear dial.
