i: Setting the ISO Speed

Set the ISO speed (image sensor's sensitivity to light) to suit the
ambient light level. Regarding the ISO speed during movie shooting,
see pages 224 and 226.
ISO Speed Guide
ISO Speed
L, 100 - 400
400 - 1600
1600 - 51200, H1, H2
* Higher ISO speeds will result in grainier images.
If [z2: Highlight tone priority] is set to [Enable], you cannot select "L"
(equivalent to ISO 50), ISO 100/125/160, "H1" (equivalent to ISO
102400), and "H2" (equivalent to ISO 204800) (p.150).
Shooting in high temperatures may result in images that look grainier.
Long exposures can also cause irregular colors in the image.
When you shoot at high ISO speeds, noise (such as dots of light and
banding) may become noticeable.
Shooting long exposures at high ISO speeds may result in irregular
colors in the image.
When shooting in conditions that produce an extreme amount of noise,
such as a combination of high ISO speed, high temperature and long
exposure, images may not be recorded properly.
