■ Rechargeable AA Ni-MH Batteries
Caring for the Flash
The capacity of Ni-MH batteries may be temporarily reduced when new, after long
periods of disuse, or if they are repeatedly recharged before being fully discharged.
This is normal and does not indicate a malfunction.
To ensure continued enjoyment of the product, observe the following precau-
tions.
Storage and Use
The flash draws a small amount of current even when off . Ni-MH batteries that
have been left in the flash for an extended period may be drawn down to the point
that they no longer hold a charge. Batteries that no longer hold a charge even
after repeatedly being discharged and recharged have reached the end of their
service life and must be replaced.
If the flash will not be used for an extended period, remove batteries. Do not store
or use the flash in locations that are:
• exposed to rain, steam, or smoke
• very humid or extremely dusty
• exposed to direct sunlight or very high temperatures, such as in a closed vehicle
on a sunny day
• extremely cold
Ni-MH batteries can be recharged in a battery charger (sold separately). Batteries
may become warm to the touch after charging. Refer to the instructions provided
with the charger for more information. Use the charger with compatible batter-
ies only.
• subject to strong vibration
• exposed to strong magnetic fields, such as near a broadcasting antenna, power
line, radar emitter, motor, transformer, or magnet
• in contact with volatile chemicals such as pesticides
• next to rubber or vinyl products
Ni-MH batteries gradually lose their charge when not in use.
■ Disposal
Dispose of used batteries in accord with local regulations.
■ Water and Sand
Exposure to water and sand can also damage the flash and its internal circuitry and
mechanisms. When using the flash at the beach or seaside, avoid exposing the
flash to water or sand. Do not place the flash on a wet surface.
■ Condensation
Sudden increases in temperature, such as occur when entering a heated building
on a cold day, can cause condensation inside the flash. If this occurs, turn the flash
off and wait for droplets to evaporate.
Cleaning
Use a blower to remove dust from the light-emitting section or other parts of the
flash, then gently wipe with a soft, dry cloth. Any remaining stains can be removed
by wiping gently with a piece of FUJIFILM lens-cleaning paper to which a small
amount of lens-cleaning fluid has been applied. Care should be taken to avoid
scratching any parts of flash, particularly the light-emitting section. The body of
flash can be cleaned with a soft, dry cloth.

Welcome to the worldwide family of FUJIFILM owners.
Note that it cannot be used with other cameras. Please read this own-
er’s manual carefully so that you can use this unit correctly.
Features and Functions of the FUJIFILM EF-20
★ The position of the subject or the use of bounce lighting may make
the brightness level insufficient or excessive. This unit has an EV
ADJUST button that allows you to easily increase or decrease the
brightness as required.
★ Bounce lighting is possible at an upward angle of up to 90 degrees.
★ Less than half the size of our previous model and weighing about
85 grams less, the EF-20 boasts a compact, lightweight design that
provides a high degree of freedom in camera work. In addition,
when the unit is not installed on the camera, the shoe section can
be ratated inside the flash body so that the unit can be carried even
in a shirt pocket.

About the READY Lamp
Installing the Batteries
The firing power may be insufficient immediately after lighting of the READY lamp.
To obtain optimum brightness for shooting, wait a few seconds before releasing
the shutter after the READY lamp comes on.
Slide the battery cover release button
downward to open the battery com-
partment.
Insert two new“AA”-size alkaline or NiMH
batteries into the battery compartment,
ensuring that the polarity indications “+”
and“−”are aligned correctly. The unit will
not operate properly if the batteries are
installed incorrectly.
q
w
*
If the READY lamp blinks for more than 30 seconds, it is likely that the batteries
are exhausted and need replacement (provided that the unit is not mounted on
the camera and the READY lamp blinks for more than 30 seconds after previous
firing).
Close the battery cover until it clicks.
Press the POWER switch to the “ON”
position. When the unit is switched on,
it will start charging with a slight hum-
ming sound and the READY lamp starts
to blink.
Now the unit is ready for shooting. (The
READY lamp stops blinking and re-
mains illuminated when the unit is fully
charged.)
e
Mounting the Unit on the Camera
Be sure to set the POWER switch to OFF before mounting or dismounting the unit.
If the POWER switch is left ON, unexpected flashing or a malfunction of the camera
may result.
Firmly slide the flash onto the camera’s shoe and turn the lock ring to the left to
fix the flash.
Once the flash has been mounted on the shoe, the shutter speed will be auto-
matically set when both the flash and camera are turned on.
q
w
To switch the power off, press the POW-
ER switch again. The READY lamp will go
off and the unit will not flash.
r
Now the camera is ready for flashing.
*
Be careful not to short-circuit the shoe
terminals while the unit is switched on
without being mounted on the camera.
Otherwise, unexpected firing or a failure
may result.
Test Firing
*
It is recommended to use the NiMH (Nickel Metal Hydride) batteries in order to
decrease the charging time and increase the firing count.
After the READY lamp lights steadily, press the TEST/ READY
button to activate test firing. This allows you to confirm that
the flash fires.

adjustment indicator in the“-“ direction until the desired brightness is obtained.
The adjustment with the ED ADJUST button is invalid when no EV adjustment indica-
tor is lit (i.e. when the TTL auto brightness adjustment is not activated). Make sure
that one of the EV adjustment indicators is lit before pressing the EV ADJUST button.
TTL Effective Range
When the subject is within the TTL
effective range, the selected EV ad-
justment indicator lights for about
seconds after firing. If the indicator
does not come on, approach the subject or open up the aperture (decrease the f-
number) and retry shooting. Changing the ISO speed to a higher sensitivity (higher
value) can also be helpful.

To exit from the EV adjustment mode, press the EV ADJUST button again. Alterna-
tively, the EV adjustment mode can also be exited by pressing the POWER switch to
OFF then ON again.
Bounce Lighting
*
The effective TTL range is shorter than usual immediately after the READY lamp
comes on.
The light-emitting section of the EF-20 can be pointed upward for bounce light-
ing.
If the flash is fired by pointing the light-emitting section directly at the subject, the
picture may look unnatural due to a strong shadow produced behind the subject
under certain conditions. In such a case, pointing the light-emitting section to the
ceiling may make it possible to take beautiful pictures with softer, more natural
shadows.
If the Picture is Too Bright or Too Dark
The EF-20 has an EV ADJUST button for fine adjust-
ment of the brightness level.
Use this button to adjust the brightness to obtain a
satisfactory effect in the following cases.
The brightness of bounce lighting may sometimes be insufficient depending
on the distance of the ceiling (wall) surface where the light is reflected. In this
case, press the EV ADJUST button to adjust the EV value in the positive direction,
position the AF frame in the viewfinder on the subject and half-press the shut-
ter release button. Confirm that the “N” mark is visible in the viewfinder and that
the shutter speed and f-stop are correct before fully pressing the shutter release
button.
★ When satisfactory brightness cannot be obtained
during daylight sync flashing (in outdoor shoot-
ing under sunlight, the strobe light can be used as an auxiliary light source to
minimize shadows on the subject formed by the sun) or shooting against light.
★ When you want to take several pictures by varying the brightness.
★ When the brightness is insufficient in bounce lighting.
First, shoot a picture in standard auto mode (when the EV adjustment indicator is
lit) and check it on the monitor. If you find that the brightness is too high or low,
press the EV ADJUST button to fine adjust the brightness and take another picture.
If the picture is darker than expected, press the EV ADJUST button once to increase
the EV by one step so that the red “+0.5” EV adjustment indicator lights up. In this
condition, the unit emits light by increasing the brightness by +0.5 EV. After shoot-
ing, check the picture on the monitor again. If the brightness is still insufficient, press
the button again so that the “+1” EV adjustment indicator lights up and retry shoot-
ing.
If the picture is too bright, press the EV ADJUST button to change the lighting EV

To prevent damage or malfunction, do not
bend the light-emitting section above 90 de-
grees.
Important Note on Successive Firing
Bounce lighting is possible simply by turn-
ing the light-emitting section up toward the
ceiling,. All other operations are identical to
shooting with direct lighting. However, note
that the brightness may drop to about 25%,
though this is variable depending on the
color and material of the reflecting surface. It
is therefore recommended to open up the aperture (to decrease the f-number
as much as possible). The surface used for bounce lighting should be as white as
possible and its reflectivity as high as possible. Note that, in color photography,
if the reflecting surface has a color, the colored reflection will stain the subject
in that color.
To prevent degradation due to overheating that may result from successive firing,
it is recommended to pause firing for more than 10 minutes after successive firing.
