Thank you for purchasing a Canon product.
The Canon Speedlite 430EX is a multi-feature flash unit for Canon EOS
cameras. It works automatically with E-TTL II, E-TTL, and TTL
autoflash systems. It can be used as an on-camera flash or as part of a
wireless flash system.
Read this instruction manual while also referring to your
camera’s instruction manual.
Before using the Speedlite, read this instruction manual and your camera’s
instruction manual to familairize yourself with the Speedlite operations.
The basic operation is the same as with normal AE shooting.
When the 430EX is attached to an EOS camera, almost all automatic
exposure control for flash photography is handled by the camera.
Although the 430EX is an external flash unit, it works automatically and
seamlessly like the camera’s built-in flash.
It is automatically compatible with the camera’s flash metering
mode (E-TTL ll, E-TTL, and TTL).
The camera controls the Speedlite automatically in the following flash metering
modes:
1. E-TTL II autoflash (evaluative flash metering with preflash reading/lens
distance information)
2. E-TTL autoflash (evaluative flash metering with preflash reading)
3. TTL autoflash (off-the-film metering for real-time flash metering)
Regarding the camera’s available flash metering modes, refer to the
“External Speedlite” specification in the “Specifications” of your
camera’s instruction manual. The Speedlite’s major specifications are
listed in “External Flash Items.”
The camera instruction manual’s chapter on flash photography will refer
to cameras having 1 and 2 as a Type-A camera (compatible with ETTL II or E-TTL). And cameras having 3 (compatible with only TTL) are
called Type-B cameras.
* This instruction manual assume that you are using the 430EX with a Type-A
camera.
For Type-B cameras, see page 35.

Friday, June 10, 2005 4:40 PM
Using E-TTL II and E-TTL Autoflash in the Shooting Modes
Just set the camera’s shooting mode to <W> (aperture-priority AE),
<X> (shutter-priority AE), or <q> (manual) and you can use E-TTL
II/E-TTL autoflash.
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 a standard exposure.
X
If the aperture display blinks, it means that the background exposure will
be underexposed or overexposed. Adjust the shutter speed until the
aperture display 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 a standard exposure.
If the background is dark like a night scene, a slow sync speed will be used
to obtain a standard exposure of both the main subject and background.
Standard exposure of the main subject is obtained with the flash, while a
W standard exposure of the background is obtained with 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 display blinks, it means that the background
exposure will be underexposed or overexposed. Adjust the aperture until
the shutter speed display stops blinking.
Select this mode when you want to set both the shutter speed and aperture
manually.
q Standard exposure of the main subject is obtained with the flash. The
exposure of the background is obtained with 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 <V> (Program AE) mode.

Friday, June 10, 2005 4:40 PM
Bounce Flash
By pointing the flash head toward a wall or ceiling, the flash will bounce
off the surface before illuminating the subject. This can soften shadows
behind the subject for a more natural-looking shot. This is called bounce
flash.
Set the Bounce Direction
Hold down the <z> button and turn the flash head.
If the flash coverage is set automatically, the flash coverage will be set
to 50mm.
The LCD panel will also display <O> mm. (p.18)
You can also set the flash coverage manually.
If the wall or ceiling is too far away, the bounced flash might be too weak
and result in underexposure.
The wall or ceiling should be a plain, white color for high reflectance. If
the bounce surface is not white, a color cast may result in the picture.
After you take the shot, if the flash exposure confirmation lamp does not
light, use a larger aperture opening and try again. With a digital camera,
you can also increase the ISO speed.

24mm to 105mm. The flash coverage can be set automatically or
manually. Also, with the built-in wide panel, the flash coverage will be
compatible with ultra wide-angle lenses as short as 14mm.
Press the <G> button.
Press the <9> button to change the
flash coverage.
When the flash coverage is set
automatically, <d> is not displayed.
If you set the flash coverage manually, make sure it covers the lens focal
length so that the picture will not have a dark periphery.
Using the Wide Panel
Pull out the wide panel and place it over
the flash head as shown.
The <G> button will not
work.
The flash coverage will not be compatible with the EF15mm f/2.8
Fisheye lens.
For the effective lens focal length (or crop factor), refer to the camera’s
instruction manual.
If you use bounce flash with the wide panel in place, the entire display on
the LCD panel will blink as a warning. Since the subject will be
illuminated by both the bounce flash and direct flash, it will look
unnatural.
Pull out the wide panel gently. Using excessive force may detach the
wide panel.

Automatic Setting of Flash Coverage for the Camera’s Image Size
EOS digital cameras have one of three image sizes. The lens’ effective
focal length will differ depending on the camera’s image size. The
Speedlite automatically recognizes the EOS digital camera’s image size
and automatically sets the flash coverage for lens focal lengths from
24mm to 105mm.
When the Speedlite is attached to a compatible camera, <s> will
appear on the Speedlite’s LCD panel.

About Color Temperature Information Transmission
When the flash fires, the color temperature information is transmitted to
certain specific EOS digital camera. This feature optimizes the flash
picture’s white balance. When the camera’s color balance is set to
<A> or <Q>, it will work automatically.
To see if this feature works with your camera, see the “White Balance”
specification in the “Specifications” of your camera’s instruction manual.

Wireless Flash
With multiple Canon Speedlites having the wireless flash feature, you can
create various lighting effects with the same ease as using normal E-TTL II
autoflash.
The settings you input with the master unit attached to the camera are also
transmitted to the slave unit(s) controlled by wireless. Therefore, you need
not operate the slave unit(s) at all during the shoot.
For details on wireless flash photography and operating the master unit,
see the master unit’s instruction manual. The procedure below applies to a
master unit attached to the camera and slave unit(s) controlled by wireless.

Use the mini stand (tripod socket provided) to prop up the slave unit.
Use the bounce feature to swing the slave unit’s flash body so that
the wireless sensor faces the master unit.
Indoors, the wireless signal may also bounce off the wall so there is
more leeway in positioning the slave unit(s).
After positioning the slave unit(s), be sure to test the wireless
operation before shooting.
Do not place any obstacles between the master unit and slave
unit(s). Obstacles can block the transmission of wireless signals.
Even with multiple slave units, all of them will be controlled in the same
way via wireless.
The Speedlite’s zoom setting will be set automatically to 24mm. It is
possible to change the master unit’s zoom setting. However, note that
the master unit transmits wireless signals to the slave unit(s) with the
preflash. Therefore, the flash coverage must cover the slave unit’s
position. If you change the master unit’s zoom setting, be sure to test the
wireless operation before shooting.
If the slave unit enters auto power off, it can be turned on again by
pressing the master unit’s test firing button.
If the 430EX is set as a slave unit and remains in auto power off mode for
more than 8 hours, it will not turn on even if you try to fire a test flash with
the master unit. In this case, press the slave unit’s test firing button to
turn it on.
A test flash cannot be fired while the camera’s operation timer 4 or 0
is active.

Using Fully Automatic Wireless Flash
Flash exposure compensation and other settings set with the master
unit will also be automatically set in the slave units. Thus, you need not
make settings on the slave unit(s). Wireless flash with the following
settings can be done in the same way as with normal flash shooting.
• Flash exposure compensation
• High-speed sync (FP flash)
• FE lock
• FEB
• Manual flash
• Stroboscopic flash
With FE lock, if even one Speedlite will result in underexposure, the <Q>
icon will blink in the viewfinder. Open the aperture more or move the
slave unit closer to the subject.
With a wireless flash system, the master unit’s settings will not be
displayed on the 430EX’s LCD panel.
Setting Communication Channel
If there is another Canon wireless flash system nearby, you can change
the channel No. to prevent signal confusion. Both the master and slave
units must be set to the same channel No.
