Under the [7Custom Functions (C.Fn)] menu, if [Highlight tone priority] is set to [1: Enable], the settable ISO speed range will be ISO 200 - 3200 (p.186).

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, light dots, etc.) may appear.

Under the [7Custom Functions (C.Fn)] menu, if [ISO expansion] is set to [1: On], ISO 6400 and “H” (ISO 12800) can also be set (p.184).
