* High ISO speeds will result in grainier images.

Under [54: Custom Functions (C.Fn)], if [2: ISO expansion] is set to [1: On], “H” (equivalent to ISO 25600) can also be set (p.294).

Under [54: Custom Functions (C.Fn)], if [3: Highlight tone priority] is

set to [1: Enable], ISO 100 and “H” (equivalent to ISO 25600) cannot be selected (p.295).
