Assigning frequently used functions to buttons (Custom Key Setting)

still image, movie

You can use the custom key function to assign the functions you use most frequently to easily operable keys. This lets you skip the process of selecting items from MENU, so you can recall the functions more quickly.

You can separately assign functions to custom keys for the still image shooting mode, movie shooting mode, and playback mode.

  • Assignable functions vary depending on the keys.

You can assign functions to the following keys.
