Assigning frequently used functions to buttons (Custom Key Setting)

still image, movie, slow&quick motion

You can use the custom key function to assign the functions you use most frequently to easily operable buttons. 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 and movie shooting mode.

  • Assignable functions vary depending on the buttons.

You can assign functions to the following buttons.

  1. MENU (Setup) → [Operation Customize][Custom Key Setting].
    • If you want to assign a function to recall while shooting movies, select [Custom Key Setting].
  2. Move to the [Rear] screen using the top/bottom side of the control wheel. Then, select [Center Button] and press the center of the control wheel.
  3. Select [Subject Recognition AF] using the top/bottom/left/right side of the control wheel, and then press the center.
    • If you press the center button while shooting and eyes are detected, [Subject Recognition AF] will activate and the camera will focus on the eyes. Shoot images while holding down the center button.


  • By pressing a button to which a function can be assigned on the custom key setting screen, you can go to the setting screen for the pressed button (except for some buttons).
  • You can also assign shooting functions to the focus hold button on the lens. However, some lenses do not have a focus hold button.
