About Auto ISO

This mode sets the ISO speed automatically between ISO 100 - 800 to suit the shooting mode and ambient light level. For flash and <a> (manual) exposures, ISO 400 is set. When you press the shutter button halfway, the automatically-set ISO speed is displayed in the viewfinder and on the LCD monitor.

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.

Under the [7Custom Functions (C.Fn)] menu, if [Highlight tone priority] (p.156) is set to [1: Enable], the settable ISO speed range will be ISO 200 - 1600.
