also enables high-speed sync (FP or Focal-Plane flash), FE (Flash Exposure)
lock, FEB (Flash Exposure Bracketing), bounce flash and area AF-assist.
When used with Type-B cameras (listed below), the 550EX works as a TTL
autoflash unit.
The CE Mark is a Directive conformity mark of the European
Community (EC)
The apparatus shall not be exposed to dripping or splashing.
Batteries shall not be exposed to excessive heat such as sunshine, fire or the like.
Dry batteries shall not be subjected to charging.

Installing Batteries
• Use four new batteries of the same type. When replacing batteries, replace
all four batteries at one time.
• Size-AA lithium batteries can also be used.
• Although non-alkaline, manganese batteries may also be used, the number
of flashes will be less.
• Remove the batteries when the 550EX will not be used for an extended
period.
• In low temperatures, take two sets of batteries and keep one set warm in a
pocket, etc., and use the batteries alternately.
• To prevent faulty connections, make sure the battery contacts are clean. If
necessary, use a clean cloth to wipe the battery contacts.
• In the case of size-AA nickel-hydride and size-AA lithium batteries, the shape
of the contacts is not standardized. Be sure that the batteries are compatible
with the flash unit before buying.

• The minimum recycling time applies in the E-TTL or TTL mode while the maximum recycling time
applies in the manual or full-output (1/1) mode.
• The minimum flash count applies in the manual or full-output (1/1) mode while the maximum
flash count applies in the E-TTL or TTL mode.
• The above specifications are based on Canon’s testing standards.
• Using size-AA nickel-hydride batteries will yield only about 70 to 80 percent of the flashes (1550
mAh at full output) obtainable with size-AA alkaline batteries. The recycling time will also be
about half the time with size-AA alkaline batteries.

• While High-Voltage Pack E315’s main switch is still on, do not clean the connector
plug with water or a metal pin and do not touch the plug.
• Even when an external power source is used, batteries must be installed in the 550EX
to power the internal circuitry.
• The 550EX uses both the internal and external power sources to recharge the flash.
Therefore, the internal power source may become exhausted sooner than the external
power source. For prolonged flash photography, keep a spare set of batteries handy
for the internal power source.

12. AF-Assist Beam
In low-light or low-contrast situations, the
Speedlite emits the AF-assist beam
automatically to assist autofocusing. The
AF-assist beam is compatible with the
AF of all EOS cameras. The AF-assist
beam is effective with 28mm and longer
lenses. Its effective range in darkness is
indicated in the table below. See page
123 for details on when the AF-assist
beam is emitted.

Basic Flash Photography
When the Speedlite 550EX is attached to a Type-A camera such as the EOS3, you can take flash pictures with E-TTL autoflash as easily as normal
autoexposure (AE) pictures.
As with evaluative metering, the E-TTL autoflash system uses a multi-zone
sensor. A preflash is fired for evaluative flash metering and the reading is
stored in memory. Since E-TTL autoflash is linked to the active focusing point,
the flash exposure is highly accurate. The result is a natural-looking flash
picture with excellent balance between the flash light and ambient light.

This section assumes that the Speedlite 550EX is used with a Type-A camera.
Before proceeding, first turn on the EOS-3 and the 550EX.
Set the 550EX’s wireless selector to OFF.
For EOS-3 operations, refer to the EOS-3 Instructions.

flash exposure confirmation lamp
lights.
When a correct flash exposure has
been obtained, the flash exposure
confirmation lamp lights for about 3
sec. If the lamp does not light, the
flash may have been insufficient,
resulting in underexposure. In such a
case, check that the pilot lamp is red,
then move closer to the subject and
take the picture again.
• The preflash is fired to obtain an evaluative flash meter reading.
• The main flash illuminates the subject for the actual picture.
● Fill Flash
Fill flash can be used outdoors in daylight to supplement existing light. It can
soften shadow areas of the subject or illuminate a backlit subject.
When fill flash is used, the flash exposure level is reduced automatically so that the
subject’s illumination by the flash balances well with the background’s ambient light.
Instead of having a properly-exposed subject and an underexposed background, both
the subject and background are exposed correctly for a natural-looking flash picture.

2. Using Flash in Other Camera Modes
Flash photography is also automatic in the other picture-taking modes. In the
Av (aperture-priority AE), Tv (shutter speed-priority AE), and M modes, the
E-TTL autoflash system sets the flash exposure automatically. The camera
sets the necessary shutter speed (in the Av mode), aperture (in the Tv mode),
or flash output (in the M mode). Flash photography is as easy as normal AE
picture-taking.

● Balanced Flash Exposures
In low-light situations, the exposure level can be balanced between the
subject and background by using a slow sync speed. You can obtain
balanced flash exposures automatically by setting the camera’s picture-taking
mode to Av. The camera then sets the sync speed automatically to suit the
background. Using a tripod is recommended to prevent camera shake.

• To disable automatic balanced flash exposures, set the camera's picture-taking mode
to M. You can then set the desired shutter speed and aperture manually. See page

Based on the shutter speed and aperture you set, the E-TTL autoflash system
controls the flash exposure automatically.
• If you are using the Canon EF 135mm f/2.8 soft focus lens on your camera without a
tripod, setting the shutter speed and aperture manually is most effective for obtaining
soft-focus effects. Follow the procedure below.
1) Set an aperture near the maximum aperture.
2) Set the minimum shutter speed required to prevent camera shake.
3) Check that the flash has recharged, then take the picture.
• To obtain balanced flash exposures in the Tv mode, set the shutter speed until the
meter reading indicates a correct exposure.
• To obtain balanced flash exposures in the M mode, set the shutter speed and
aperture until the meter reading indicates a correct exposure.
• Under flourescent lighting, the photo may have a greenish cast. And under tungsten
lighting, the photo may have an orange cast.

9. Second-Curtain Synchronization
Normally, the flash fires in synchronization with the first shutter curtain when
the shutter is fully open. With second-curtain synchronization, the flash fires
immediately before the second shutter curtain closes at the end of the
exposure. With second-curtain synchronization and a slow shutter speed, you
can create a trailing blur (illuminated by ambient light) that trails a moving
subject (illuminated by the flash) to give a natural-looking illusion of motion.

Wireless Flash Photography
This section covers wireless flash photography with the 550EX. It explains the
550EX’s built-in master and slave flash features.
550EX Wireless Flash Features
• A wireless flash system with multiple Speedlite 550EXs can be used as
easily as a single, on-camera Speedlite 550EX.
• Up to three 550EXs or three groups of 550EXs can be set as slave units
for automatic control.
• 550EXs set as slave units can be positioned to obtain the desired lighting
effects. All of their settings are controlled by the master unit and camera.

• This section assumes that the Speedlite 550EX is used with the EOS-3.
• Before proceeding, first turn on the main switch on the EOS-3 and 550EX.
• In these Instructions, a Speedlite 550EX whose wireless selector has been set to
is called the “master unit” and a 550EX whose wireless selector has been
set to
is called a “slave unit.”
• For EOS-3 operations, refer to the EOS-3 Instructions.
• With the EOS ELAN II/ELAN IIE, 50/50E, 300/REBEL 2000, 500N/REBEL G,
3000N/66/REBEL XSN, IX, and IX 7/IX Lite, only one slave group can be used for
wireless E-TTL autoflash control.
• Quick flash cannot be used with wireless flash photography.

[1] Wireless System Setup and Testing
The wireless flash system can be setup in one of two ways: 1 With a 550EX
set as the master unit and one or more 550EXs set as slave units. 2 With
Speedlite Transmitter ST-E2 (sold separately) used as the master unit and
one or more 550EXs set as slave units.
This section describes the procedure for the former. For the latter, refer to the
Instructions for Speedlite Transmitter ST-E2.
1. Setting the 550EX as the Master Unit
Attach the 550EX to the camera and set
the wireless selector to
. This
550EX will then be the “master unit.” The
master unit’s wireless signal is
transmitted to the slave unit(s) at almost
the same time as the preflash.
The master unit’s flash head zoom setting is set automatically to
. This gives the
wireless signal the maximum coverage of 80°. You can also press the
button to
change the zoom setting manually. However, this will narrow the wireless signal’s
coverage.

• If a slave unit does not fire, place it closer to
the master unit or angle the sensor more
toward the master unit and try again.
• In a wireless flash system, the flash mode (E-TTL autoflash, high-speed sync, manual
flash, stroboscopic flash), flash exposure compensation, flash exposure bracketing,
and other settings are all set with the master unit. The master unit transmits all these
settings to the slave units by wireless signals. Controlling slave unit(s) is the same as
controlling one on-camera Speedlite.
• A modeling flash can be fired to check the lighting effects (lighting balance, shadows,
etc.) before you take the picture. See page 50.
• Make sure the slave units are within the effective range of the master unit.
• After the picture is taken, the slave unit’s operation result is displayed on the LCD
panel.
• With the slave unit's main switch set to SE (Save Energy), the slave unit turns off
automatically if it is left unused for over 60 minutes*. While the slave unit is off due to
this SE mode, SE is displayed on the LCD panel. Within 1 hour** after the slave unit
turns off in the SE mode, the slave unit can be turned on again by pressing the master
unit's test firing button.
• If the manual flash mode has been set and you press the master unit’s pilot lamp, all
the slave units will fire a test flash simultaneously at the manually-set flash output.
• After pressing the shutter button halfway, test firing cannot be executed during the first

[2] Wireless E-TTL Autoflash
Wireless E-TTL autoflash with multiple Speedlite 550EXs can be used in one
of two ways:
(1)
OFF : All slave units fire at the same flash output.
(2)
ON
: Slave units with different slave IDs (A, B, or C) can be
fired at different flash outputs to produce a flash ratio.
• A flash ratio can be set only with the EOS-1D, 1V, 3, D60, D30, ELAN 7/7E, and 30/33.
• With the EOS ELAN II/ELAN IIE, 50/50E, 300/REBEL 2000, 500N/REBEL G, 3000N/66/REBEL
XSN, IX, and IX 7/IX Lite, a flash ratio cannot be set with the master unit.
1. Wireless E-TTL Autoflash With Flash Ratio OFF
If no flash ratio is desired, the slave ID does not matter. It can be A, B, or C.
All the slave units will fire at the same flash output. The E-TTL autoflash
system controls the total flash amount automatically to obtain a correct flash
exposure.

For Type-B Cameras
Basic Flash Photography
When the Speedlite 550EX is attached to a Type-B camera such as the EOS1N, you can take flash pictures with TTL autoflash as easily as normal
autoexposure (AE) pictures. Flash photography can be fully automatic—all
you do is press the shutter button. Or you can set the desired shutter speed
and aperture and still obtain autoflash exposure.
With the EOS-1N, the flash exposure is controlled by real-time, 3-zone, offthe-film TTL autoflash metering linked to the active focusing point.
•
•
•
•
This section assumes that the Speedlite 550EX is used with the EOS-1N.
Before proceeding, first turn on the EOS-1N and the 550EX.
Set the 550EX’s wireless selector to OFF.
For EOS-1N operations, refer to the EOS-1N Instructions.

the flash fires, check that the

flash exposure confirmation lamp
lights.
When a correct flash exposure has
been obtained, the flash exposure
confirmation lamp lights for about 3
sec. If the lamp does not light, the
flash may have been insufficient,
resulting in underexposure. In such a
case, check that the pilot lamp is red,
then move closer to the subject and
take the picture again.
● Fill Flash
Fill flash can be used outdoors in daylight to supplement existing light. It can
soften shadow areas of the subject or illuminate a backlit subject.
When fill flash is used, the flash exposure level is reduced automatically so that the
subject’s illumination by the flash balances well with the background’s ambient light.
Instead of having a properly-exposed subject and an underexposed background, both
the subject and background are exposed correctly for a natural-looking flash picture.

2. Using Flash in Other Camera Modes
Flash photography is also automatic in the other picture-taking modes. In the
Av (aperture-priority AE), Tv (shutter speed-priority AE), and M modes, the
TTL autoflash system sets the flash exposure automatically. The camera sets
the necessary shutter speed (in the Av mode), aperture (in the Tv mode), or
flash output (in the M mode). Flash photography is as easy as normal AE
picture-taking.

When the shutter button is pressed completely, the flash fires and the picture is taken. The flash
output is controlled by the TTL autoflash system based on the aperture set by you or the camera.
The TTL autoflash system meters the light reflected off the film during the exposure and cuts off
the flash when the proper exposure is obtained.
• The background’s exposure is set with the shutter speed and aperture combination.
• If the camera is set to the
mode (Full Auto), the shutter speed and aperture will be
set in the same way as in the P mode (Program AE).
• If the DEP mode (depth-of-field AE) is used with the 550EX, it will be the same as
using the P mode (Program AE).

● Balanced Flash Exposures
In low-light situations, the exposure level can be balanced between the
subject and background by using a slow sync speed. You can obtain
balanced flash exposures automatically by setting the camera’s picture-taking
mode to Av. The camera then sets the sync speed automatically to suit the
background. Using a tripod is recommended to prevent camera shake.

Based on the shutter speed and aperture you set, the TTL autoflash system controls
the flash exposure automatically.
• If you are using the Canon EF 135mm f/2.8 soft focus lens on your camera without a
tripod, setting the shutter speed and aperture manually is most effective for obtaining
soft-focus effects. Follow the procedure below.
1) Set an aperture near the maximum aperture.
2) Set the minimum shutter speed required to prevent camera shake.
3) Check that the flash has recharged, then take the picture.
• To obtain balanced flash exposures in the Tv mode, set the shutter speed until the
meter reading indicates a correct exposure.
• To obtain balanced flash exposures in the M mode, set the shutter speed and
aperture until the meter reading indicates a correct exposure.

With stroboscopic flash, a rapid series of flashes is fired. It can be used to
record multiple images of a moving subject in a single photograph for later
study.
You can set the firing frequency (the number of flashes per sec. expressed as
Hz) from 1 Hz to 199 Hz. The firing frequency can be set in 1-Hz increments
from 1 Hz to 20 Hz, in 5-Hz increments from 25 Hz to 50 Hz, and in 10-Hz
increments from 60 Hz to 199 Hz.
• Stroboscopic flash cannot be used with the EOS 750 and EOS 850 cameras.
Up to 100 flashes can be fired

7. Second-Curtain Synchronization
Normally, the flash fires in synchronization with the first shutter curtain when
the shutter is fully open. With second-curtain synchronization, the flash fires
immediately before the second shutter curtain closes at the end of the
exposure. With second-curtain synchronization and a slow shutter speed, you
can create a trailing blur (illuminated by ambient light) that trails a moving
subject (illuminated by the flash) to give a natural-looking illusion of motion.

For Type-B Cameras
Wireless Flash Photography
This section covers wireless flash photography with the 550EX. It explains the
550EX’s built-in master and slave flash features. A wireless flash system with
multiple Speedlite 550EXs can be used as easily as a single, on-camera
Speedlite 550EX.
With Type-B cameras, the 550EX offers the following wireless flash features:
[1] Wireless System Setup and Testing (page 100)
[2] Wireless Manual Flash (page 107)
[3] Wireless Stroboscopic Flash (page 109)
[4] Independent Settings With a Slave Unit (page 110)
• This section assumes that the Speedlite 550EX is used with the EOS-1N.
• Before proceeding, first turn on the main switch on the EOS-1N and 550EX.
• In these Instructions, a Speedlite 550EX whose wireless selector has been set to
<
> is called the “master unit” and a 550EX whose wireless selector has been
set to <
> is called a “slave unit.”
• For EOS-1N operations, refer to the EOS-1N Instructions.

[1] Wireless System Setup and Testing
The wireless flash system can be setup in one of two ways: 1 With a 550EX
set as the master unit and one or more 550EXs set as slave units. 2 With
Speedlite Transmitter ST-E2 (sold separately) used as the master unit and
one or more 550EXs set as slave units.
This section describes the procedure for the former. For the latter, refer to "[4]
Manual or Stroboscopic Flash With a Slave Unit" on page 110,111.
1. Setting the 550EX as the Master Unit
Attach the 550EX to the camera and set
the wireless selector to
. This
550EX will then be the “master unit.” The
master unit’s wireless signal is
transmitted to the slave unit(s) at almost
the same time as the shutter release.
The master unit’s flash head zoom setting is set automatically to
. This gives the
wireless signal the maximum coverage of 80˚. You can also press the
button to
change the zoom setting manually. However, this will narrow the wireless signal’s
coverage.
2. Setting the 550EX as a Slave Unit
Set the wireless selector to
on
the 550EX to be used as a slave unit. A
550EX set in this way is called a “slave
unit.”
• The slave unit’s flash head zoom setting is
set automatically to

toward the master unit and try again.
• In a wireless flash system, all the settings can be set with the master unit. The master
unit transmits all these settings to the slave units by wireless signals. Controlling slave
unit(s) is the same as controlling one on-camera Speedlite.
• Make sure the slave units are within the effective range of the master unit.
• After the picture is taken, the slave unit’s operation result is displayed on the LCD
panel.
• With the slave unit's main switch set to SE (Save Energy), the slave unit turns off
automatically if it is left unused for over 60 minutes*. While the slave unit is off due to
this SE mode, SE is displayed on the LCD panel. Within 1 hour** after the slave unit
turns off in the SE mode, the slave unit can be turned on again by pressing the master
unit's test firing button.
• If the manual flash mode has been set and you press the master unit’s pilot lamp, all
the slave units will fire a test flash simultaneously at the manually-set flash output.
• After pressing the shutter button halfway, test firing cannot be executed during the first
6 sec. when the camera is metering the scene.

[4] Manual or Stroboscopic Flash With a Slave Unit
Manual flash or stroboscopic flash can be set manually with a slave unit. The
setting is independent from the master unit. The master unit just triggers the
slave unit which fires according to its own independent (manual or
stroboscopic flash) setting. This feature can be used in the following
situations:
(1) As with studio flash, you can set the slave unit’s flash output yourself for
wireless manual flash photography.
(2) For wireless manual flash photography with Wireless Transmitter ST-E.
1. Manual Flash With a Slave Unit
On a slave unit with the wireless selector
set to <

The Canon Speedlite 550EX is a powerful, high-output flash unit featuring ETTL (Evaluative-Through-The-Lens) autoflash control. It can be used as an oncamera Speedlite or as a master or slave unit in a wireless, multi-Speedlite
system.
When used with Type-A cameras (listed below), the 550EX obtains natural-looking flash pictures by balancing the flash output and existing light. The 550EX
also enables high-speed sync (FP or Focal-Plane flash), FE (Flash Exposure)
lock, FEB (Flash Exposure Bracketing), bounce flash and area AF-assist.
When used with Type-B cameras (listed below), the 550EX works as a TTL
autoflash unit.

Community (EC)
