Page 50: The Fn Button
The role played by the Fn button can be selected using the Fn BUTTON option in the shooting menu. The options available include multiple exposure, depth-of-field preview, the self-timer, sensitivity, image size, image quality, dynamic range, film simulation, white balance, AF-mode, movierecording, RAW/JPEG toggle, and customsettings.
* The Fn BUTTON menu can also be displayed by pressing and holding the Fn button (1 sec+)
