Getting Started and
Basic Operations
This chapter describes the preparations before starting ash
photography and the basic shooting operations.
Cautions for ring continuous ash
oTo avoid wearing out and damaging the ash head due to
overheating, do not re the ash continuously at full output
more than 30 times. After ring the ash continuously at full
output this many times, stop using the ash for at least 40
min.
oIf you re the ash continuously at full output for the
above listed number of times, and then re the ash
again repeatedly at short intervals, the safety function
may activate and restrict ash ring. When ash ring is
restricted, the ring interval is automatically set to approx.
45 sec. Stop using the ash for at least 40 min.
oFor details, see “Flash Firing Restrictions due to
Temperature Increase” on page 56.

12
Installing the Batteries
Install two AA/R6 batteries for power supply.
1 Open the cover.
2
Install the batteries.
3 Close the cover.

13
Installing the Batteries
CAUTION
oDo not use “AA/R6 lithium batteries”.
Note that certain AA/R6 lithium batteries may become extremely hot in
rare cases during use. Due to safety reasons, do not use “AA/R6 lithium
batteries”.
oDo not use the Speedlite while touching the same part for a long
period of time.
Even if the product does not feel too hot, prolonged contact with the same
body part may cause skin redness or blistering due to low-temperature
contact burns. Using a tripod is recommended in very hot places or for
people with circulation problems or less sensitive skin.
Using AA/R6 batteries other than the alkaline type may cause contact
failure due to the irregular shape of the battery contacts.
oUse a new set of two batteries of the same brand. When replacing the
batteries, replace both at the same time.
oAA/HR6 Ni-MH batteries can also be used.
oFor details on the ash interval and ash count, refer to the separate
Supplemental Information.

14
Attaching and Detaching the Speedlite to
and from the Camera
Always turn o󰀨 the Speedlite beforehand.
1 Attach the Speedlite.
2
Secure the Speedlite.
3 Detach the Speedlite.

15
Switching Flash Coverage
Adjust the ash head so the ash coverage is suitable for the focal
length of your lens.
Using lenses with a wider angle of view than the ash coverage may
cause vignetting.
Normal position
zMaximum ash coverage can be
used with RF/EF 24mm (EF-S/EF-M
15mm) lenses.
Extended
zCan be used with RF/EF 50mm (EF-
S/EF-M 30mm) or larger lenses.

16
Turning on the Power
(1) (3)(2)
1 Set the Mode dial to <a> (1) or
<K> (2).
2
Check that the ash is ready.
zThe ash-ready lamp (3) is red when
the ash is fully charged.
zShooting is also possible while the
ash-ready lamp is blinking (using
Quick ash). Flash output will be 1/2
to 1/6 of full output.
Mode Dial
z<K>
The ash res constantly as you shoot.
z<a>
The ash res automatically as needed (depending on shooting
modes and conditions) when used with cameras that support auto
ash ring.
In [A]or [d] mode on the EOS R, the ash also turns on or o󰀨 in
response to these operations with the camera power switch.
z<J>
Turns the ash o󰀨.
z<[.4/5/6>
Set when using the ash as a receiver in optical wireless
ash photography. For details, see Chapter 4, “Wireless Flash
Photography: Optical Transmission.”

17
Turning on the Power
oLeaving the Mode dial set to <a> when using cameras that support
auto ash ring may prevent full charging and ring during shooting,
depending on shooting conditions or the state of the battery.
oQuick ash is not available under these conditions.
• Cameras that do not support E-TTL II/E-TTL
• Optical wireless ash photography
• Stroboscopic ash
• Manual ash photography with ash output outside the range 1/4 to
1/128
oWith the Mode dial set to <a>, aiming the ash head straight ahead is
recommended. Switch to suitable ash coverage for the lens’ angle of
view (p.15).
oWith cameras that do not support auto ash ring, the ash will always
re when you shoot with the Mode dial set to <a>.

18
a:
Fully Automatic Flash Photograph y
When you set the camera’s shooting mode to <d> (Program AE) or a
fully automatic mode, you can shoot in E-TTL II/E-TTL fully automatic
ash mode.
Note that for some cameras, [E-TTL II ash metering] is automatically
used when the ash Mode dial is set to <a>.
1 Set the ash mode to [E-TTL II ash
metering].
zSelect the ash mode setting item
from the camera’s [Flash function
settings] or [External ash func.
setting] screen (p.28).
zSelect [E-TTL II ash metering].
2
Switch the ash coverage.
zSwitch to a suitable ash coverage for
your lens (p.15).
3 Focus and shoot.
zConrm that <I> is lit in the
viewnder or (in Live View) on the
screen.
oIf your shots are dark (underexposed), try approaching the subject or
increasing the ISO speed.
o“Fully automatic” refers to <A>, <1>, and <C> shooting modes.

19
E-TTL II/E-TTL Autoflash by Shooting Mode
Set the camera’s shooting mode to <s> (shutter-priority AE), <f>
(aperture-priority AE), <t> (exible-priority AE), or <a> (manual
exposure) to use E-TTL II/E-TTL autoash for that mode.
s
Enables you to set the shutter speed manually. Based on your shutter
speed, the camera sets an aperture to provide standard exposure.
oIf the aperture value blinks, adjust the shutter speed until it stops
blinking.
f
Enables you to set the aperture manually. Based on your aperture, the
camera sets a shutter speed to provide standard exposure.
oIf the shutter speed blinks, adjust the aperture until it stops blinking.
t
Enables you to set the shutter speed or aperture manually.
oIf the aperture value blinks when you set a shutter speed, adjust the
shutter speed until it stops blinking.
oIf the shutter speed blinks when you set an aperture, adjust the
aperture until it stops blinking.
a
Enables you to set both the shutter speed and aperture manually.
Light from the ash provides standard exposure for the main subject, but
exposure for the background varies depending on your specied shutter
speed and aperture.
If you use the <Z> or <Y> shooting mode, the result will be the same
as using the <d> (Program AE) mode.
