Also, with [ISO AUTO] (
) selected, you can set the maximum ISO speed, or select the rate of change.

4. If the following icon is shown, the setting is complete (if setting [ISO Speed] to 400).
CAUTION
- Raising the [ISO Speed] increases the shutter speed and allows the flash to reach subjects at far distances. Therefore, it is possible to shoot images with less subject blur or camera shake even in dark places.
- However, the higher the [ISO Speed], the more the noise stands out (more uneven areas in an image).
- Lowering the ISO speed results in sharper images, but there may be an increased chance of subject or image blurring in certain shooting conditions.
NOTE
- If [ISO3200] () still is not enough to suppress camera shake, the [Low Light] () mode allows ISO speed settings of [ISO4000] (
), [ISO5000] (
), [ISO6400] (
), [ISO8000] (
), [ISO10000] (
) and [ISO12800] (
). - To select [Low Light], set the [Mode Dial] to the [Low Light] () mode.
- In [Low Light] mode, depending on the scene, the [ISO speed] is set higher and the shutter speed is set faster than in [AUTO] (
) mode so that you can shoot in dark places with reduced camera shake and subject blur. This mode is recommended for shooting in candlelit or similarly lit scenes. - When [Low Light] mode is set, recording pixels are fixed to (
) size (1824 x 1368 pixels).
