Getting Started and
Basic Operations
This chapter describes the preparations before starting
flash photography and the basic shooting operations.
Cautions for firing continuous flash
To avoid degrading and damaging the flash head due to
overheating, limit firing the flash continuously at full output
up to 30 times. After firing the flash continuously at full
output for 30 times, allow a rest time of at least 10 min.
If you fire the flash continuously at full output for the above
listed number of times, and then fire the flash again
repeatedly at short intervals, the safety function may
activate and restrict flash firing. With flash firing restriction
level 1, the firing interval is automatically set to approx. 8
sec. If this happens, allow a rest time of at least 40 min.
For details, see “Flash Firing Restriction due to Temperature
Increase” on page 96.
When you are not performing bounce flash photography, set the
<X> bounce mode switch to the <0°> position (p.11). For more
information on bounce flash photography, see Chapter 3 “Bounce
Flash Photography” (p.41).

Installing the Batteries
CAUTION
Do 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”.
When performing continuous flash, do not touch the flash head,
batteries, or the area near the battery compartment.
When continuous flash or modeling flash is repeatedly fired at short
intervals, do not touch the flash head, batteries, or the area near the battery
compartment. The flash head, batteries, and area near the battery
compartment may become hot, resulting in the risk of burn.
Do 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 very sensitive skin.
Using AA/R6 batteries other than the alkaline type may cause contact failure
due to the irregular shape of the battery contacts.
When <!> is displayed or the LCD panel display turns off during
recharging, replace the batteries with new ones.
Use a new set of four batteries of the same brand. When replacing the
batteries, replace all four at one time.
AA/HR6 Ni-MH batteries can also be used.

You can press the test flash button
(flash-ready lamp) to fire a test flash.
Quick Flash Function
The Quick flash function enables flash photography when the flashready lamp is lit green (before the flash is fully charged). Quick flash is
available regardless of the camera’s drive mode setting. Although the
flash output will be approx. 1/2 to 1/6 of the full output, it is useful for
shooting with a shorter firing interval.
During manual flash photography, this function is available when the
flash output is set to 1/4 to 1/128. Note that you cannot use Quick flash
with the receiver unit during optical transmission wireless shooting.
When the power is turned on, the flash head may automatically operate
(rotate).
When Quick flash is fired during continuous shooting, underexposure
may occur since the flash output decreases.
When the 3/1/o/7/2 timer of the camera is operating, a test
flash cannot be performed.
21

If the subject is dark (underexposed) when you check the shot image,
move closer to the subject and shoot again. You can also increase the
ISO speed when using a digital camera.
“Fully automatic” refers to <A>, <1>, and <C> shooting modes.
Even when attached to a camera that supports the E-TTL II autoflash
system, <a> is displayed on the LCD panel.
24
E-TTL II/E-TTL Autoflash by Shooting Mode
Simply by setting the camera’s shooting mode to <s> (shutter-priority
AE), <f> (aperture-priority AE), or <a> (manual exposure), you can
execute E-TTL II/E-TTL autoflash suitable for each shooting mode.
Select this mode when you want to set the shutter speed manually.
The camera will then automatically set the aperture matching the shutter
speed to obtain the standard exposure based on the metering of the camera.
s
If the aperture value blinks, it means that the background exposure will
be underexposed or overexposed. Adjust the shutter speed until the
aperture value stops blinking.
Select this mode when you want to set the aperture manually.
The camera will then automatically set the shutter speed, matching the
aperture to obtain the standard exposure based on the metering of the camera.
For low-light scenes, a slow sync speed will be used to obtain the standard
exposure for both the main subject and background. The standard exposure for
the main subject is obtained with the flash light, while the standard exposure for
f
the background is obtained with a long exposure using a slow shutter speed.
Since a slow shutter speed will be used for low-light scenes, using a
tripod is recommended.
If the shutter speed blinks, it means that the background exposure will
be underexposed or overexposed. Adjust the aperture until the shutter
speed stops blinking.
a
Select this mode if you want to set both the shutter speed and aperture
manually.
Standard exposure of the main subject is obtained with the flash light. The
exposure of the background changes according to the shutter speed and
aperture combination you set.
If you use the <Z> or <Y> shooting mode, the result will be the same as
using the <d> (Program AE) mode.

E-TTL II/E-TTL Autoflash by Shooting Mode
Auto Zoom Adjustment to Image Sensor Size
EOS DIGITAL cameras have three sizes of image sensors, and the
effective shooting angle of view of the attached lens varies depending
on the size of image sensor. 470EX-AI automatically recognizes the
image sensor size of the EOS DIGITAL camera and automatically sets
the flash coverage that is ideal for the effective shooting angle of view of
a lens for the focal length range of 24-105mm.
Color Temperature Information Transmission
This function adjusts the white balance depending on the color
temperature of the flash light by transmitting the color temperature
information to the EOS DIGITAL camera when the flash fires. When you
set the camera’s white balance to <A>, <Aw>, or <Q>, the
function is enabled automatically.
Refer to the specifications in your camera’s Instruction Manual to find
out if it is compatible with this function.
Bounce Function
See Chapter 3, “Bounce Flash Photography” (p.41-64).
When the <X> bounce mode switch is set to the <0°> position and the
flash head is facing a direction other than straight forward, the <X> lamp
blinks. Pressing the shutter button halfway automatically returns the position
of the flash head to the forward-facing position. (The <X> lamp turns off.)
26
E-TTL II/E-TTL Autoflash by Shooting Mode
AF-Assist Beam
When it is difficult to autofocus on the
subject in low-light or when contrast is
low during viewfinder shooting, the
infrared AF-assist beam built into the
flash is automatically emitted to help
autofocus.
The AF-assist beam supports most of the EOS cameras’ AF points. The
AF-assist beam covers the angle of view of 28 mm or longer lens focal
length, and its effective range (at 28 mm focal length) is approx. 0.7 - 10
m/2.3 - 32.8 ft. at the center in the viewfinder and approx. 1 - 5 m/3.3 16.4 ft. at the periphery (AF points other than the center AF point).
If a peripheral AF point is selected, or a wide-angle or telephoto lens is
used, achieving focus may be difficult with an EOS-dedicated, external
Speedlite’s AF-assist beam. In such a case, use the center AF point or an
AF point close to the center.
During Live View shooting, the AF-assist beam is emitted even when the
AF method is set to [Quick mode].
AF-assist beam firing can be disabled (C.Fn-08, p.86).
The AF-assist beam type that uses intermittent flashes (a series of small

Modeling Flash
To avoid degrading and damaging the flash head due to overheating,
limit firing the modeling flash up to 20 times. After firing modeling flash
for 20 times, allow a rest time of at least 10 min.
If you fire the modeling flash for the above listed number of times, and
then fire the flash again repeatedly at short intervals, the safety function
may activate and restrict flash firing. With flash firing restriction level 1,
the firing interval is automatically set to approx. 8 sec. If this happens,
allow a rest time of at least 40 min.
During Live View shooting, firing modeling flash (by operating the
camera) is not possible.

Bounce Flash
Photography
This chapter describes functions related to the bounce
flash function, such as flash photography that uses the
AI.B full-auto function, AI.B semi-auto function, manual
bounce, and bounce adapter.
Cautions for the AI Bounce Flash Function
During AI.B full-auto and AI.B semi-auto shooting, the flash
head moves and fires automatically. The flash head may fire in
an unintended direction. Before performing AI bounce flash
photography, be sure to warn those around you. Additionally,
when you want to perform AI bounce flash photography, follow
the precautions below.
• Make sure your eyes are not close to the flash head.
• The flash head may come in contact with objects. Make sure
your face, head, and the like are not close to the flash head.
• The flash head moves. Be sure to hold the camera securely.
• Do not allow your hair or the like to get entangled with the
flash head.
• Be careful of the orientation of the flash head in low angle
shooting.
41
X AI Bounce Flash
By pointing the flash head toward a ceiling, you can utilize the reflection
of the flash light off the surface for flash photography, making it possible
to soften the shadows of the subject for a more natural-looking shot.
This shooting technique is called “Bounce flash photography”.
Bounce flash photography allows you to get a more natural-looking shot
compared to techniques that light the subject directly with the flash light.
Shooting with the appropriate exposure, however, may require some
knowledge and experience.
This Speedlite comes with an “AI bounce (AI.B) flash function” that
enables you to perform bounce flash photography automatically. There
are two AI bounce flash modes: “AI.B full-auto mode” and “AI.B semiauto mode”. With AI.B full-auto function, the camera performs the
bounce flash photography automatically, requiring only simple
operations.
Bounce Mode
Slide the <X> bounce mode switch to switch the AI bounce flash
mode.
0° : Set when performing normal flash
photography (not bounce flash
photography).
Y: Allows you to perform “AI.B semiauto shooting” (p.45, 56).
Z: Allows you to perform “AI.B fullauto shooting” (p.43, 46, 48).
When the bounce mode is switched, the flash head automatically moves
to the forward-facing position.
When the flash head is moving, do not touch it.
When you are to perform manual bounce flash photography, set P.Fn-09
to 1 (p.92) and set the switch to the <0°> position.
42
X AI Bounce Flash
W AI.B Full-Auto
This mode is geared for beginners. In this mode, the camera performs
the bounce flash photography automatically, requiring only simple
operations. When the <X> AI.B full-auto distance measurement start
button is pressed, the flash fires briefly (preflash) to measure the
distance to the subject and the distance to the ceiling for bouncing the
flash light. Based on the result of distance measurement, the orientation
(bounce angle) of the flash head is automatically set.
For AI.B full-auto shooting, see pages 46-55.
Press the <X> button to
perform the following operations automatically.
1. Fires the flash
toward the subject.
2. Fires the flash
toward the ceiling.
3. Sets the bounce
angle automatically.
When using an EOS DIGITAL camera released in or after the second half of
2017 (p.46), you can perform the same distance measurement operation as
described above using the camera’s depth-of-field preview button.
43
X AI Bounce Flash
Note if you change the orientation (position) of the camera, doubleclicking the camera’s shutter button (pressing the shutter button halfway
two times in a row within a short period) makes the flash head move
automatically, resetting the bounce angle to substantially the same
angle as before you changed the orientaion of the camera.

W AI.B Full-Auto
Depending on the camera used, AI.B (AI bounce flash) full-auto mode
compatibility and some of the operations to start AI.B full-auto shooting
vary (EOS cameras released up to the first half of 2014 do not
support AI.B full-auto shooting).
During AI.B full-auto shooting, the flash fires briefly (preflash) before the
image is shot to measure the distance to the subject and the distance to
the ceiling for bouncing the flash light. This operation automatically sets
an appropriate bounce angle for the subject.
You can perform this operation using one of the following two methods.
The operating procedure differs according to the camera used.
1. Use the Speedlite’s <X> AI.B full-auto distance measurement
start button.
2. Use the camera’s depth-of-field preview button.
AI.B Full-Auto Compatible Cameras and Operation Restrictions

W AI.B Full-Auto Shooting
Before performing AI.B (AI bounce flash) full-auto shooting, check if the
camera used supports full-auto bounce flash photography (p.46).
For an overview of AI.B full-auto shooting, see page 43. Additionally,
before performing AI.B full-auto shooting, review the “Safety
Precautions” (p.8), “General Cautions for AI.B Full-Auto Shooting and
AI.B Semi-Auto Shooting” (p.60), and the like.
Guidelines for Shooting Conditions in AI.B Full-Auto Mode
When performing AI.B full-auto shooting, perform bounce flash
photography using the figure below as reference. Additionally, with the
subject positioned in the center of the screen, press the <X> button
(to start distance measurement operation).
Distance to ceiling
Approx. 1 - 3 m /
3.3 - 9.8 ft.
Shooting distance
Approx. 1 - 5 m / 3.3 - 16.4 ft.
Under conditions such as when the subject is far away, the ceiling is far
away, the ceiling is a dark color, the ceiling is stepped or uneven, the
camera’s ISO speed setting is low, or a large aperture value is set,
underexposure (insufficient exposure) is prone to occur.
When the distance to the ceiling is approx. 7 m / 23 ft. or greater
(estimate), or when the shooting angle exceeds approx. 60° upward or
approx. 60° downward, the flash head automatically moves to the
forward-facing position and normal flash shooting is performed without a

Double-clicking the camera’s shutter button (pressing the shutter
button halfway two times in a row within a short period) activates the
flash head to move automatically, resetting the bounce angle to
substantially the same angle as before you changed the orientation
(position) of the camera.
Pictures are underexposed (insufficiently exposed).
During bounce flash photography, less light reaches the subject and
thus underexposure (insufficient exposure) is prone to occur. Take
the action such as taking the picture as close to the subject as
possible, increasing the camera’s ISO speed, or opening the
aperture of the lens before shooting.
Further, when the ceiling or wall for bouncing the flash light on is too
far away, the ceiling is a dark color, or the ceiling is stepped or
uneven, shooting with the appropriate exposure may not be possible
since not enough light may reach the subject.
The color of the subject is not right.
If the surface for bouncing the flash light is not white, a color cast
may result in the picture or shooting with the appropriate exposure
may not be possible since the bounced flash light may not reach the
subject. Select a ceiling or wall that is close to a white color for
bouncing the flash light off for high reflectance.

When a picture is taken with the camera oriented downward or upward,
the appropriate bounce angle may not be automatically set. If this
happens, take the picture using the following technique.
• Perform AI.B semi-auto shooting (p.56)
• Set the <X> switch to the <0°> position so that the flash head is
facing forward (p.42).
• Manual bounce flash photography (p.61)
When the <X> button is pressed during movie shooting, although
AI.B full-auto distance measurement operation (preflash) is performed,
flash photography cannot be performed.
When you turn the flash head, turn it slowly. While it may make a sound
when you turn the flash head, it is not a malfunction. However, it may
result in a mechanical failure if you continuously turn the flash head fast.
During AI.B full-auto shooting, you can fire the flash at the desired bounce
angle as in manual bounce flash photography by pressing the <z>
button after determining the orientation (position) of the camera and
adjusting the flash head.

FAQ
When bounce angle automatic correction is not performed even when
the orientation (position) of the camera is changed, underexposure
(insufficient exposure) occurs, or the color of the subject is not right, see
page 53.
59
General Cautions for AI.B Full-Auto Shooting and AI.B Semi-Auto
Shooting
If the camera is held at too steep an angle after a change of orientation
(position), automatic bounce angle correction may not be performed. In
addition, automatic bounce angle correction will not be performed when
the change of orientation makes it impossible to reset to the stored
bounce angle.
Since the turning angle of the flash head is indicated in 5° increments,
the angle may be displayed with a margin of error to an extent of 5°
(before and after the automatic correction) such as when the bounce
angle is automatically corrected.
When the flash settings are cleared during AI.B full-auto shooting or AI.B
semi-auto shooting (p.40), the bounce angle stored (registered) in the
Speedlite is cleared. Therefore, pressing the shutter button halfway
returns the flash head to the forward-facing position.
AI bounce flash photography cannot be performed with the release
button on a remote controller or the touch operation of the camera (not
supported).
Notes for AI.B Full-Auto Shooting and AI.B Semi-Auto Shooting
When using an EOS DIGITAL camera released in and after the second half
of 2017 (p.46), “AI_b” is displayed on the camera’s viewfinder as well as the
LCD panel, and [AI BOUNCE] is displayed on the LCD monitor if the flash
head moves in the following three cases, 1, 2, or 3.
1. When the <X> button or the like is pressed for distance measurement
operation during AI.B full-auto shooting (with the camera’s metering timer
active).
2. When bounce angle correction is performed by double-clicking the
shutter button during AI.B full-auto shooting or AI.B semi-auto shooting.
3. When the position of the flash head is (inadvertently) moved by pressing
the shutter button halfway to automatically correct the bounce angle after
distance measurement operation during AI.B full-auto shooting or after
the bounce angle was stored (registered) in the Speedlite during AI.B
semi-auto shooting.

m Manual Bounce Flash Photography
When P.Fn-09 is set to 0 (p.92), you cannot manually set the bounce
angle (the flash head automatically returns to the 0° position when the
shutter button is pressed halfway even when you manually set the
bounce angle).
If the ceiling or wall for bouncing the flash light on is too far away,
shooting with the appropriate exposure may not be possible since the
bounced flash light may not reach the subject.
If the picture appears dark, use a larger aperture opening (smaller f/
number) and try again. You can also increase the ISO speed when using
a digital camera.
Select a ceiling or wall that is close to a white color for bouncing the flash
light off for high reflectance. If the bounce surface is not white, a color
cast may result in the picture or shooting with the appropriate exposure
may not be possible since the bounced flash light may not reach the
subject.
When Quick flash is fired with bounce flash, underexposure may occur
since the flash output decreases.
When you turn the flash head, turn it slowly. While it may make a sound
when you turn the flash head, it is not a malfunction. However, it may
result in a mechanical failure if you turn the flash head fast.
When the flash head is turned while the flash coverage is set to <L>
(automatic setting), the flash coverage is set at 50 mm and <--> is
displayed.
You can also manually set the flash coverage (p.34).

q Combined Use with the Bounce Adapter
If you attach the provided bounce adapter to the Speedlite and bounce
the flash light on the ceiling or wall, etc., you can spread the flash light
across a larger area and suppress the shadows on the subject.
Also, if the bounce angle is set to 90° to bounce the flash light on the
ceiling, etc., the diffused flash light emitted from the sides of the bounce
adapter falls on the front of the subject (shooting distance guidance:
within approx. 1.5 m/4.9 ft., at ISO 100 with f/2.8), further suppressing
the shadow on the subject. When shooting portraits, the catchlight effect
can also be obtained.

2 TakeDuring
AI.B full-auto shooting (p.48),
pressing the <X> button
automatically sets the bounce angle
so that the flash head is facing toward
the ceiling.
Take the picture with the flash light
bouncing off the ceiling, walls, or the
like.
63
q Combined Use with the Bounce Adapter
When the bounce adapter is attached, or when the bounce adapter and
the wide panel are used together, underexposure may result since the
flash output decreases. Take necessary countermeasures such as
increasing the ISO speed on the camera or applying flash exposure
compensation (p.30).
Since the flash guide number decreases when the bounce adapter is
attached, focusing with AF-assist beam using a series of small flashes
may not be possible. Using infrared AF-assist beam is recommended
(P.Fn-04-0, p.89).
When Quick flash (p.21) is fired with the bounce adapter attached, taking
the picture after the flash-ready lamp is lit in red is recommended since
the flash output may not be sufficient.
The flash coverage is set automatically when the bounce adapter is
attached. You cannot change the setting.
If you attach the bounce adapter to the flash when using an EOS
DIGITAL camera released up to 2004, set the white balance to <A>. If
you shoot with <Q>, appropriate white balance may not be obtained.
The flash light is further softened when the wide panel (p.35) is used
together with the bounce adapter.
If the subject is dark (underexposed) when you check the shot image,
perform flash exposure compensation (p.30). You can also increase the
ISO speed when using a digital camera.
During AI.B full-auto shooting and AI.B semi-auto shooting, you can
press the <z> button to store (register) the bounce angle in the
Speedlite even when the bounce adapter is mounted.

When using a Speedlite without a function for switching the firing groups
(A, B, C) in &, you can use the Speedlite as a receiver in firing group A
during optical transmission wireless shooting (you cannot use it as a
receiver in firing group B or C).
During AI.B full-auto shooting, do not use the Off-Camera Shoe Cord
OC-E3 (an appropriate bounce angle is not automatically set).
Do not use 470EX-AI, attaching it to the Speedlite Bracket SB-E2 (sold
separately) or the like. 470EX-AI does not fit securely to the bracket and
will be somewhat unstable, possibly causing the flash head to come into
contact with the bracket section during AI bounce flash.

f Flash Firing Restrictions due to Temperature Increase
When continuous flash or modeling flash is repeatedly fired in short
intervals, the temperature of the flash head, batteries, and the area near
the battery compartment may increase.
When you perform firing repeatedly, the firing interval increases in
steps to avoid degrading or damaging the flash head due to
overheating. When you perform firing repeatedly even more in this
state, flash firing is restricted automatically.
Furthermore, when flash firing is restricted, a warning icon is
displayed to indicate the increase in temperature, and the firing
interval (with which the flash photography can be performed) will be
automatically set to approx. 8 sec. (level 1) or approx. 20 sec. (level 2).
Temperature Increase Warning
As the internal temperature of the Speedlite increases, the warning is
displayed in two levels. When you perform continuous firing repeatedly
even more in the state in level 1, the state changes to level 2.

CAUTION
When performing continuous flash, do not touch the flash head,
batteries, or the area near the battery compartment.
When continuous flash or modeling flash is repeatedly fired at short intervals,
do not touch the flash head, batteries, or the area near the battery
compartment. The flash head, batteries, and area near the battery
compartment may become hot, resulting in the risk of burn.
Do not open or close the battery compartment cover while flash firing is
being restricted. Doing so is very dangerous since the flash firing
restriction is canceled.
Even when level 1 warning is not displayed, the firing interval will be
extended as the flash head begins to heat up.
If level 2 warning is displayed, allow a rest time for at least 40 min.
Even if you stop flash firing after level 1 warning is displayed, level 2
warning may be displayed.
If flash photography is performed in high temperatures, the firing
restrictions may be activated before the number of flashes listed in the
table on the preceding page is fired.
For cautions on the number of flash firings, see page 17 (continuous
flashes) or page 39 (modeling flash).
The Speedlite may not fire in rare cases due to environmental factors
such as temperature rise.
When the bounce adapter is used, the number of continuous flashes
until the warning is displayed becomes slightly fewer.
When C.Fn-22-1 is set (p.87), the warning with red illumination of the
LCD panel will not be displayed even if the temperature of the flash head
rises.

The power does not turn on.
Make sure the batteries are installed in the correct orientation (p.18).
Make sure the battery compartment cover is closed (p.18).
Replace the batteries with new ones.
The Speedlite does not fire.
Insert the mounting foot into the camera’s hot shoe all the way, slide
the lock lever to the right, and secure the Speedlite to the camera
(p.20).
If the <G> indication remains displayed for approx. 30 sec. or
longer, replace the batteries (p.18).
If the electrical contacts of the Speedlite or camera are dirty, wipe
the contacts (p.10) with a dry cloth, etc.
When you perform continuous firing repeatedly over a short period
of time, causing the temperature of the flash head to rise and flash
firing to be restricted, the firing interval increases (p.96).
The power turns off by itself.
The Speedlite’s auto power off has been activated (p.22). Press the
camera’s shutter button halfway or press the Speedlite’s test flash
button (p.21).

Troubleshooting Guide
Pictures are underexposed or overexposed.
If the main subject looks very dark or very bright, set flash exposure
compensation (p.30).
If there is a highly reflective object in the picture, use FE lock (p.31).
With high-speed sync, the faster the shutter speed, the lower the
guide number becomes. Move closer to the subject (p.32).
The bottom of the picture looks dark.
Move at least 0.7 m/2.3 ft. away from the subject.
Remove the lens hood if attached.
The picture periphery looks dark.
Set the flash coverage to <L> (automatic setting, p.34).
When manually setting the flash coverage, set a flash coverage
wider than the shooting angle of view (p.34).
Make sure C.Fn-21-1 is not set (p.87).
The picture is very blurred.
When the shooting mode is set to the <f> aperture-priority AE
mode and the scene is dark, slow sync is enabled automatically (the
shutter speed becomes slower). Use a tripod, or set the shooting
mode to the <d> program AE or fully automatic mode (p.25). Note
that you can also set the sync speed in [Flash sync. speed in Av
mode] (p.68).
99
Troubleshooting Guide

Troubleshooting Guide
Bounce Flash Photography
The flash head moves on its own.
When Speedlite is first started and the shutter button on the camera
is pressed halfway with the flash head in a position other than the
forward-facing (0°) position, the flash head automatically moves to
the forward-facing (0°) position.
The AI bounce flash function is activated. When you do not want to
use the AI bounce flash function, set the <X> switch to the <0°>
position (p.42).
When the position of the flash head changes after you press the
<z> button and store (register) the bounce angle in the
Speedlite, pressing the camera’s shutter button halfway returns the
flash head to the registered position.
“AI.B[” is displayed. / The flash head does not move.
When Speedlite is not attached to the camera, the “AI.B[”
animation is displayed and the flash head’s AI bounce flash
operation is not performed.
When the orientation (position) of the camera has changed, doubleclicking the shutter button (pressing the shutter button halfway two
times in a row within a short period) activates the bounce angle
correction.
In AI.B full-auto mode, the flash head does not move even
when I press the camera’s depth-of-field preview button.
Check whether or not the camera’s depth-of-field preview button
functions as an AI.B full-auto distance measurement start button (p.46).
The modeling flash fires when the camera’s
depth-of-field preview button is pressed.
Check whether or not the camera’s depth-of-field preview button
functions as an AI.B full-auto distance measurement start button
(p.38, 46, 85).
101
Troubleshooting Guide
A warning is displayed.
For warning displays, see page 52.
The flash coverage cannot be set manually.
The flash coverage cannot be manually set in AI.B full-auto
shooting, with the bounce adapter attached, or with wide panel used.
The bounce angle cannot be set manually.
When you want to perform manual bounce flash photography, see
page 61.
Pictures are underexposed.
During bounce flash photography, less light reaches the subject and
thus underexposure (insufficient exposure) is prone to occur. Take
the action such as taking the picture as close to the subject as
possible, increasing the camera’s ISO speed, or opening the
aperture of the lens before shooting.
When the ceiling or wall for bouncing the flash light on is too far
away, the ceiling is dark, or the ceiling is stepped or uneven,
shooting with the appropriate exposure may not be possible since
not enough light may reach the subject.
The color of the subject is not right.
If the surface for bouncing the flash light is not white, a color cast
may result in the picture or shooting with the appropriate exposure
may not be possible since the bounced flash light may not reach the
subject. Select a ceiling or wall that is close to a white color for
bouncing the flash light off for high reflectance.
102
Troubleshooting Guide
Modeling flash does not work.
Depending on the camera used, the camera’s depth-of-field preview
button may function as the <X> full-auto distance measurement
start button. For details, see pages 46 and 85.
