Notes
• [ISO AUTO] is selected when using the following functions:
– [Intelligent Auto]
– [Scene Selection]
– [Anti Motion Blur]
– [Sweep Panorama]
– [3D Sweep Panorama]
• The larger the number, the higher the noise level.
• When the exposure mode is set to [Program Auto], [Aperture Priority], [Shutter Priority], and [ISO] is set
to [ISO AUTO], ISO is automatically set between ISO100 and ISO1600.
• You can select up to ISO3200 for movie recording. When you start recording movies with an ISO higher
than 3200, ISO becomes 3200 automatically, and returns to the previous value when recording is
finished.
• The [ISO AUTO] setting is not provided in [Manual Exposure]. If you change the exposure mode to
[Manual Exposure] with the [ISO AUTO] setting, it is switched to 100. Set the ISO according to your
shooting conditions.
Adjusting ISO Sensitivity (Recommended Exposure
z
Index)
ISO setting (speed) is the sensitivity to light of recording media that incorporates an image
sensor that receives light. Even when the exposure is the same, images differ depending on
the ISO setting.
Sets the ISO sensitivity automatically.
Sets the sensitivity to light of the imaging sensor. Higher
sensitivities enable faster shutter speeds and/or smaller
apertures (larger F-values). The higher the sensitivity, the more
image noise can become visible.
High ISO sensitivity
With high ISO sensitivity, images will be captured with an
appropriate brightness even under insufficient exposure.
However, increasing ISO sensitivity will cause images to
become noisy.
Low ISO sensitivity
You can record smooth images. However, compensation for
low ISO sensitivity will be made by slowing down the shutter
speed. You should take camera shake or movement of subjects
into account, too.
