[Fast AF-ON] has been added to the roles that can be assigned using Custom Setting g2 [Custom controls] (g2: Custom Controls).

  • If [AF-ON] is selected in focus mode AF-C, the camera will focus at the speed selected for Custom Setting g6 [AF speed] (g6: AF Speed) when the control is pressed. If [Fast AF-ON] is selected, the camera will focus at maximum speed, regardless of the option chosen for Custom Setting g6.

  • Assigning [AF-ON] and [Fast AF-ON] to different controls gives you a choice of two focus speeds.
