1600 - 6400, H
If [8C.Fn II -3: Highlight tone priority] is set to [1: Enable], ISO 100/

125/160 and "H" (equivalent to ISO 12800) settings cannot be set
(p.225).
Using a high ISO speed or shooting in high-temperature conditions may

result in more grainy images. Long exposures can also cause irregular
colors in the image.
When you shoot at high ISO speeds, noise (horizontal banding, dots of

light, etc.) may appear.
With [8C.Fn I -3: ISO expansion] set to [1: On], "H" (equivalent to ISO
12800) can also be set (p.222).
