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.209).

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.206).
