About “A” (Auto) ISO Speed
If [8C.Fn II -3: Highlight tone priority] is set to [1: Enable], the
settable ISO speed range will be ISO 200 - 3200 (p.177).
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.
With [8C.Fn I -3: ISO expansion] set to [1: On], “H1” (equivalent to ISO
6400) and “H2” (equivalent to ISO 12800) can also be set (p.174).
