External Flash Units

External flash units are more powerful than their built-in counterparts. Some can function as commanders controlling remote units via optical wireless flash control.

You may be unable to test-fire the flash in some circumstances, for example when a setup menu is displayed on the camera.

Red-Eye Removal

Red-eye removal is available when an option other than [OFF] is selected for F[FLASH SETTING] > [RED EYE REMOVAL] and a [FACE DETECTION ON] option is selected for G [AF/MF SETTING] > [FACE/EYE DETECTION SETTING]. Red-eye removal minimizes “red-eye” caused when light from the flash is reflected from the subject’s retinas.

The Sync Terminal

Flash units requiring a sync cable connection cannot be used.

[SHOE MOUNT FLASH]

The following options are available when an optional shoe-mounted flash unit is attached and turned on.

To prevent the built-in flash firing when a shoe-mounted flash unit is attached, select [OFF] for F [FLASH SETTING] > [Built-In Flash].

Setting	Description
AFlash control mode	The flash control mode selected with the flash unit. This can in some cases be adjusted from the camera; the options available vary with the flash. [TTL]: TTL mode. Adjust flash compensation (A). [M]: The flash fires at the selected output regardless of subject brightness or camera settings. Output in some cases can be adjusted from the camera (B). [Multi]: Repeating flash. Compatible shoe-mounted flash units will fire multiple times with each shot. D(OFF): The flash does not fire. Some flash units can be turned off from the camera.
BFlash compensation/output	The options available vary with flash control mode. [TTL]: Adjust flash compensation (the full value may not be applied if the limits of the flash control system are exceeded). In the cases of the EF‑X20 and EF-X500, the selected value is added to the value selected with the flash unit. [M]/[MULTI]: Adjust flash output (compatible units only). Choose from values expressed as fractions of full power, from 1/1 (mode [M]) or 1/4 ([MULTI]) down to 1/512 in increments equivalent to 1/3 EV. The desired results may not be achieved at low values if they exceed the limits of the flash control system; take a test shot and check the results.
CFlash mode (TTL)	Choose a flash mode for TTL flash control. The options available vary with the shooting mode ([P], [S], [A], or [M]) selected. E([FLASH AUTO]): The flash fires only as required; flash level is adjusted according to subject brightness. A p icon displayed when the shutter button is pressed halfway indicates that the flash will fire when the photo is taken. F([STANDARD]): The flash fires with every shot if possible; flash level is adjusted according to subject brightness. The flash will not fire if not fully charged when the shutter is released. G([SLOW SYNC.]): Combine the flash with slow shutter speeds when photographing portrait subjects against a backdrop of night scenery. The flash will not fire if not fully charged when the shutter is released.
DSync	Control flash timing. H([1ST CURTAIN]): The flash fires immediately after the shutter opens (generally the best choice). I([2ND CURTAIN]): The flash fires immediately before the shutter closes.
EZoom	The angle of illumination (flash coverage) for units that support flash zoom. Some units allow the adjustment to be made from the camera. Select [AUTO] to automatically match coverage to focal length when using optional conversion lenses.
FLighting	If the unit supports this feature, choose from: J([FLASH POWER PRIORITY]): Gain range by slightly reducing coverage. K([STANDARD]): Match coverage to picture angle. L([EVEN COVERAGE PRIORITY]): Slightly increase coverage for more even lighting.
GLED light	Choose how the built-in LED light functions during still photography (compatible units only): as a catchlight (M/[CATCHLIGHT]), as an AF-assist illuminator (N/[AF ASSIST]), or as both a catchlight and an AF-assist illuminator (O/[AF ASSIST+CATCHLIGHT]). Choose [OFF] to disable the LED during photography.
GNumber of flashes ^*	Choose the number of times the flash fires each time the shutter is released in [MULTI] mode.
HFrequency ^*	Choose the frequency at which the flash fires in [MULTI] mode.

* Full value may not be applied if limits of flash control system are exceeded.

[COMMANDER (OPTICAL)]

The options will be displayed if the unit is currently functioning as a commander for Fujifilm optical wireless remote flash control.

Fujifilm optical wireless remote flash control offers a choice of four channels (Channels 1 through 4) for the exchange of optical signals between the commander and remote flash units. Separate channels can be used for different flash systems or to prevent interference when multiple systems are operating in close proximity.

The flash units can also be placed in up to three groups (A, B, and C) and flash mode and flash level adjusted separately for each group.

Setting	Description
AFlash control mode (group A) BFlash control mode (group B) CFlash control mode (group C)	Choose flash control modes for groups A, B, and C. [TTL%] is available for groups A and B only. [TTL]: The units in the group fire in TTL mode. Flash compensation can be adjusted separately for each group. [TTL%]: If TTL% is selected for either group A or B, you can specify the output of the selected group as a percentage of the other and adjust overall flash compensation for both groups. [M]: In mode [M], the units in the group fire at the selected output (expressed as a fraction of full power) regardless of subject brightness or camera settings. [Multi]: Choosing [MULTI] for any group sets all the units in all groups to repeating flash mode. All units will fire multiple times with each shot. D(OFF): If [OFF] is selected, the units in the group will not fire.
DFlash compensation/output (group A) EFlash compensation/output (group B) FFlash compensation/output (group C)	Adjust flash level for the selected group according to option selected for flash control mode. Note that the full value may not be applied if the limits of the flash control system are exceeded. [TTL]: Adjust flash compensation. [M]/[MULTI]: Adjust flash output. [TTL%]: Choose the balance between groups A and B and adjust overall flash compensation.
GFlash mode (TTL)	Choose a flash mode for TTL flash control. The options available vary with the shooting mode ([P], [S], [A], or [M]) selected. E([FLASH AUTO]): The flash fires only as required; flash level is adjusted according to subject brightness. A p icon displayed when the shutter button is pressed halfway indicates that the flash will fire when the photo is taken. F([STANDARD]): The flash fires with every shot if possible; flash level is adjusted according to subject brightness. The flash will not fire if not fully charged when the shutter is released. G([SLOW SYNC.]): Combine the flash with slow shutter speeds when photographing portrait subjects against a backdrop of night scenery. The flash will not fire if not fully charged when the shutter is released.
HSync	Control flash timing. H([1ST CURTAIN]): The flash fires immediately after the shutter opens (generally the best choice). I([2ND CURTAIN]): The flash fires immediately before the shutter closes.
