About “A” (Auto) ISO Speed
If [8C.Fn II -3: Highlight tone priority] is set to [1: Enable], “L”
(equivalent to ISO 50), ISO 100/125/160, “H1” (equivalent to ISO 12800)
and “H2” (equivalent to ISO 25600) cannot be set (p.196).
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, horizontal stripes may appear as
noise.
With [8C.Fn I -3: ISO expansion] set to [1: On], “L” (equivalent to ISO 50),
“H1” (equivalent to ISO 12800), and “H2” (equivalent to ISO 25600) can also
be set (p.193).
