P.Fn-01: AF-assist beam firing method (AF-assist beam projection method)

You can select the AF-assist beam projection method.

  • 0: Infrared AF-assist beam (Infrared AF-assist beam)

  • 1: Intermittent flash firing mode (Intermittent flash firing method)

    Fire the AF-assist beam using the intermittent flash firing method ().

Caution

  • The AF-assist beam is not projected during live view shooting.
  • If a color filter is attached (), the Speedlite will not fire intermittently to provide an AF-assist beam.
  • For the EOS R series, an AF-assist beam is projected by the intermittent flash regardless of the projection method of the AF-assist beam and whether a color filter is fitted. Note that this beam may be emitted by the camera instead of by the Speedlite, depending on ambient brightness. Also, when a color filter is fitted and the setting is set to [1: Intermittent flash firing mode (Intermittent flash firing method)], an AF-assist beam is projected by the camera.
  • For the EOS M series, an AF-assist beam is not projected by the flash.

P.Fn-02: Quick flash (Quick flash)

You can set whether to fire the flash (Quick flash) when the flash-ready lamp is still blinking in red (before fully charged), so there is less time to wait for recharging.

  • 0: ON (Enabled)
  • 1: OFF (Disabled)

Caution

  • Using Quick flash in continuous shooting () may cause underexposure, due to the reduced flash output.

P.Fn-03: Flash firing during linked shooting (Flash firing during linked shooting)

You can set whether to fire the Speedlite attached to the camera in linked shooting (). Set for each Speedlite used in linked shooting.

  • 0: OFF (Disabled)

    The Speedlite does not fire during linked shooting.

  • 1: ON (Enabled)

    The Speedlite fires during linked shooting.

Caution

  • Firing multiple Speedlites together in linked shooting may prevent suitable exposure or cause uneven exposure.

P.Fn-04: Changing the settings with the dial (Change settings with dial)

You can select whether to allow direct configuration of the kinds of functions shown in the lower figure simply by turning Select dial on screens such as this one that are accessed by pushing the joystick straight in.

  • 0: OFF (Disabled)

    Normal method of operation.

  • 1: ON (Enabled)

    Enables selection of setting items (for the flash exposure compensation amount, manual flash output, firing group control, flash ratio, flash modes in group firing, receiver firing groups, and FEB) with the joystick and direct configuration simply by turning Select dial.

    When the flash mode is set to MULTI, you can set the "flash frequency" and "number of flashes" directly, and when it is set to Ext.M, you can set the "ISO speed" and "aperture value" directly.

Caution

  • To select a setting item on the setting screen when P.Fn-04 is set to [1], press the joystick vertically or horizontally.

P.Fn-05: FEM (FE memory)

You can select whether to update, based on ETTL flash output, the flash output maintained in manual mode.

  • 0: OFF
  • 1: ON
  • 2: ON / MODE ETTL/M

Note

  • When P.Fn-05-2 is set, even if you push the joystick down to choose MODE, the mode will not change to a mode other than ETTL or M. To select another mode, push the joystick straight in to display the setting screen, press it vertically or horizontally or turn Select dial to select an item, then select the mode.

P.Fn-06: Beeping (Beeping)

You can enable beeping after the Speedlite is fully charged.

  • 0: ON

    In normal shooting (on-camera flash photography), the Speedlite beeps after it is fully charged.

    With the Speedlite set as a sender in radio transmission wireless flash photography, the sender beeps after all Speedlites (senders and receivers) are fully charged. Sender beeping enables you to confirm recharging of the entire wireless system. On receivers, P.Fn-06 can be set to [0] or [1]. With the Speedlite set as a sender in optical transmission wireless flash photography, or with Speedlites set as radio or optical wireless receivers in linked shooting (), each Speedlite set to [0] beeps after it is fully charged.

  • 1: OFF

    The Speedlite does not beep.

Caution

  • Also when set to [0], the Speedlite beeps if high flash head or battery temperature has restricted firing ().

P.Fn-07: Fan (Fan)

You can set whether to operate the fan.

  • 0: ON
  • 1: OFF

Caution

  • If the fan breaks down or the rpm is high, a warning is displayed and the fan stops.

  • When shooting a video with the flash connected to the camera, the fan actuation sound may be recorded.
  • You can force the fan to stop when P.Fn-07-1 is set.
  • When P.Fn-07-1 is set, the number of continuous flashes is lower than when the fan is moving and the required rest time until the warning icon is cleared is extended.
  • When P.Fn-07-0 is set, the fan will start when the firing or modeling lamp is lit. The fan may start even if the flash is not fired depending on the internal temperature of the flash.
  • When the fan breaks down, the number of continuous firings () will be the same as when the fan is stopped regardless of the P.Fn-07 setting.

P.Fn-08: MODELING LAMP (brightness, color) (Modeling lamp (brightness, color))

You can set the color and brightness of the modeling lamp.

Use the joystick to select LAMP brightness or LAMP color. Turn Select dial to select an option, then push the joystick straight in.

(1) Selected cursor position

(2) Default indicator

  • LAMP brightness: Press the joystick horizontally or turn Select dial to set modeling lamp brightness.
  • LAMP color: Press the joystick horizontally or turn Select dial to set the color temperature of the modeling lamp.

Note

  • You can either push the joystick to the left or right when the modeling lamp is lit, or turn Select dial and push the joystick vertically to change the brightness and color temperature.

P.Fn-09: MODELING LAMP (period of illumination) (Modeling lamp (period of illumination))

You can set the period of illumination of the modeling lamp.

  • 0: 5 min
  • 1: 30 min
  • 2: Unlimited
