Shoe-Mounted Flash Units

EF‑X500

This clip-on flash unit has a Guide Number of 50/164 (ISO 100, m/ft.) and supports FP (high-speed sync), allowing it to be used at shutter speeds that exceed the flash sync speed. Powered by four AA batteries or an optional EF-BP1 battery pack, it supports manual and TTL flash control and auto power zoom in the range 24–105 mm (35 mm format equivalent) and features FUJIFILM optical wireless flash control, allowing it to be used as a master or remote flash unit for remote wireless flash photography. The flash head can be rotated 90° up, 10° down, 135° left, or 180° right for bounce lighting.

Using Shoe-Mounted Flash Units

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

Test firing may sometimes be unavailable, for example when the camera setup menu is displayed.

Connect the flash unit and select [FLASH SETTING] > [FLASH FUNCTION SETTING] in the camera shooting menu to display flash options. The options available vary with the status of the connected unit.

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

[SYNC TERMINAL] will be displayed if [OFF] is selected for [FLASH SETTING] > [Built-In Flash] and no supported shoe-mounted flash is attached.

Flash units that support burst mode can be used for burst photography.

Third-party studio flash commanders compatible with the FUJIFILM flash system can now be used. For more information, see the documentation provided your studio flash unit.

SHOE MOUNT FLASH

The following options are available with optional shoe-mounted flash units.

Flash 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 ().
[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 ().
[MULTI]: Repeating flash. Compatible shoe-mounted flash units will fire multiple times with each shot.
[OFF]: The flash does not fire. Some flash units can be turned off from the camera.

Flash 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, EF-20, and EF-42, 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.

Flash mode (TTL)

Choose a flash mode for TTL flash control.The options available vary with the shooting mode ([P], [S], [A], or [M]) selected.

[FLASH AUTO]: The flash fires only as required; flash level is adjusted according to subject brightness. A icon displayed when the shutter button is pressed halfway indicates that the flash will fire when the photo is taken.
[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.
[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.

Sync

Control flash timing.

[1ST CURTAIN]: The flash fires immediately after the shutter opens (generally the best choice).
[2ND CURTAIN]: The flash fires immediately before the shutter closes.

Zoom

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.

Lighting

If the unit supports this feature, choose from the options below.

[FLASH POWER PRIORITY]: Gain range by slightly reducing coverage.
[STANDARD]: Match coverage to picture angle.
[EVEN COVERAGE PRIORITY]: Slightly increase coverage for more even lighting.

LED light

Choose how the built-in LED light functions during still photography (compatible units only). It can function as a catchlight ([CATCHLIGHT]), as an AF-assist illuminator ([AF ASSIST]), or as both a catchlight and an AF-ASSIST illuminator ([AF ASSIST+CATCHLIGHT]). Choose OFF to disable the LED during photography.

Number of flashes

Choose the number of times the flash fires each time the shutter is released in [MULTI] mode. Full value may not be applied if limits of flash control system are exceeded.

Frequency

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.

MASTER (OPTICAL)

The options at right will be displayed if the unit is currently functioning as master flash for FUJIFILM optical wireless remote flash control.

The master and remote units can be placed in up to three groups (A, B, and C) and flash mode and flash level adjusted separately for each group. Four channels are available for communication between the units; separate channels can be used for different flash systems or to prevent interference when multiple systems are operating in close proximity.

Flash control mode (group A)

Flash control mode (group B)

Flash 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.
[OFF]: If [OFF] is selected, the units in the group will not fire.

Flash compensation/output (group A)

Flash compensation/output (group B)

Flash 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.

Flash mode (TTL)

Choose a flash mode for TTL flash control.The options available vary with the shooting mode ([P], [S], [A], or [M]) selected.

[FLASH AUTO]: The flash fires only as required; flash level is adjusted according to subject brightness. A icon displayed when the shutter button is pressed halfway indicates that the flash will fire when the photo is taken.
[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.

Available only if the unit is mounted on the camera hot shoe as a master flash for FUJIFILM optical wireless remote flash control in [TTL], [TTL%], or [M] mode.

Number of flashes

Choose the number of times the flash fires each time the shutter is released in [MULTI] mode.
