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),
“H2” (equivalent to ISO 25600) and “H3” (equivalent to ISO 102400)
cannot be set (p.215).
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.) or irregular colors may appear. Also, if you shoot with the ISO
speed range upper limit expanded to H1, H2 or H3 with [8C.Fn I -3: Set
ISO speed range] (p.208), noise and irregular colors may become more
visible.
With [8C.Fn I -3: Set ISO speed range], the ISO speed range can be
expanded from ISO 50 (L) to ISO 102400 (H3).
