The Canon Speedlite 580EX II is an EOS-dedicated, high-output flash
unit automatically compatible with E-TTL II, E-TTL, and TTL autoflash.
It can serve as an on-camera flash as well as a master unit or a slave
unit in a wireless, multiple-Speedlite system. It has the same dust- and
water-resistance as EOS-1D series cameras.
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 familiarize yourself with the Speedlite operations.
The basic operation is as easy as with normal AE shooting.
When the 580EX II is attached to an EOS camera, almost all automatic
exposure control for flash photography is handled by the camera.
It is almost the same as using the camera’s built-in flash if it has one. You can
think of the 580EX II as a built-in, high-output flash, but attached externally.
It becomes automatically compatible with the camera’s flash
metering mode (E-TTL ll, E-TTL, and TTL).
In accordance with the camera’s flash control system, the Speedlite controls
the flash automatically in the respective flash metering mode:
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 camera instruction manual’s chapter on flash photography will refer
to cameras having flash metering modes 1 or 2 as a Type-A camera
(compatible with E-TTL II or E-TTL). And cameras having flash
metering mode 3 (compatible with only TTL) are called Type-B cameras.
* This instruction manual assumes that you are using the Speedlite
with a Type-A camera.
For Type-B cameras, see page 55.

head, do not fire more than 20 continuous
flashes. After 20 continuous flashes, allow a rest
time of at least 10 min.
If you fire more than 20 continuous flashes and
then fire more flashes in short intervals, the
inner overheating prevention function may be
activated to make the recycling time about 8 to
20 sec. If this occurs, allow a rest time of about
15 min. and the flash will then return to normal.

be locked.
Recycling Time and Flash Count (with size-AA alkaline batteries)
Based on new size-AA alkaline batteries and Canon’s testing standards.Quick flash enables a flash to be fired before flash-ready (p.10).
Flash Count
Using size-AA batteries other than the alkaline type may cause improper
battery contact due to the irregular shape of the battery contacts.
If you change the batteries after firing many flashes continuously, be
aware that the batteries might be hot.
Use a new set of four batteries of the same brand. When replacing the
batteries, replace all four at one time.
Size-AA Ni-MH or lithium batteries can also be used.

1
X The flash recycling starts.
Check that the flash is ready.
2
The pilot lamp will first turn green (ready
for quick flash), then red (flash ready).
Pressing the pilot lamp will fire a test
flash.
About Quick Flash
Quick flash enables a flash to be fired before flash-ready, when the pilot
lamp is still green.
Although the Guide No. will be 1/6 to 1/2 that of the full output, quick flash
is effective for near subjects and when you want a shorter recycle time.
Set the drive mode to single shooting. Quick flash cannot be used in the
continuous shooting, FEB, manual flash, and stroboscopic flash modes.
Quick flash can also be used during continuous flash shooting.

About Auto Power Off
To save battery power, the power will turn off automatically after a
certain period (approx. 1.5 min. to 15 min.) of idle use. To turn on the
Speedlite again, press the camera’s shutter button halfway. Or press
the Speedlite’s test firing button.
Auto Power Off can also be disabled. (C.Fn-01 → p.27)
A test flash cannot be fired while the camera’s operation timer 4 or 0
is active.
The Speedlite’s settings will be retained in memory even after the power
is turned off. To retain the Speedlite’s settings after you replace the
batteries, turn off the power and replace the batteries within 1 minute.
10
Fully Automatic Flash Shooting
When you set the camera’s shooting mode to <V> (Program AE) or
<U> (Full Auto), E-TTL II/E-TTL fully automatic flash will make it as
easy as normal AE shooting in the <V> and <U> modes.
Set the Speedlite to <a>.
1
Press the <D> button so that
<a> is displayed.
Focus the subject.
2
Press the shutter button halfway to focus.
X The shutter speed and aperture will
be displayed in the viewfinder.
Check that the <Q> icon is lit in the
viewfinder.
Take the picture.
3
Check that the subject is within the
effective range displayed on the LCD
panel.
X
Right before the shot is taken, a preflash
is fired, then the main flash is fired.
X
If a standard flash exposure was
obtained, the flash exposure confirmation
lamp will light for about 3 sec.
<a> will be displayed on the LCD panel even if the camera is
compatible with E-TTL II.
If the flash exposure confirmation lamp does not light, move closer to the
subject and take the picture again. With a digital camera, you can also
increase the camera’s ISO speed.
11
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 if you want to set both the shutter speed and aperture
manually.
Standard exposure of the main subject is obtained with the flash. The
q
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.

If flash exposure compensation has been set with both the Speedlite and
camera, the Speedlite’s flash exposure compensation amount will override
the camera’s.
Setting the flash exposure compensation can be limited to only the <9>
dial. (C.Fn-13 → p.27)
14
g
FEB
You can take three flash shots while automatically changing the flash
output for each shot up to ±3 stops in 1/3-stop increments (1/2-stop
increments if the camera enables only 1/2-stop increments). This is
called FEB (Flash Exposure Bracketing).
Select <g>.
1
Press the <8> button so that <g>
is displayed.
X The <g> icon and bracketing
amount will blink.
Set the flash exposure bracketing

X FEB will be set.
After the three shots are taken, FEB will be cancelled automatically.For FEB, set the camera’s drive mode to single shooting. Be sure the
flash is ready before shooting.
You can also combine FEB with flash exposure compensation and FE
lock.
You can prevent the FEB from being cancelled automatically after the
three shots are taken. (C.Fn-03 → p.27)
The FEB shooting sequence can be changed. (C.Fn-04 → p.27)

7: FE Lock
FE (flash exposure) lock locks the correct flash exposure setting for any
part of the scene.
With <a> displayed on the LCD panel, you press the camera’s
<7> button. If the camera does not have the <7> button, press the
<P> button.
Focus the subject.
1
Press the <7> button. (3)
2
Aim the subject at the center of the
viewfinder and press the <7>
button.
X The Speedlite will fire a preflash and
the required flash output for the
subject is retained in memory.
X “FEL” will be displayed in the
viewfinder for 0.5 sec.
Each time you press the <7>
button, a preflash will be fired and a
new flash exposure setting will be
locked.
If the subject is too far away and underexposure will result, the <Q> icon
will blink in the viewfinder. Move closer to the subject and try the FE lock
again.
If <a> is not displayed on the LCD panel, FE lock cannot be set.If the subject is too small, FE lock might not be very effective.
16
c High-speed Sync
With high-speed sync (FP flash), the flash can synchronize with all
shutter speeds. This is convenient when you want to use aperture
priority for fill-flash portraits.
Select <c>.
Press the <E> button so that
<c> is displayed.
In the viewfinder, check that the <F>
icon is displayed.
If you set a shutter speed that is the same or slower than the camera’s
maximum flash sync speed, <F> will not be displayed in the viewfinder.
With high-speed sync, the faster the shutter speed, the shorter the
effective flash range will become. Check the LCD panel for the effective
flash range.
To return to normal flash, press the <E> button again. The <c>
icon will disappear.
Stroboscopic flash cannot be set.
17
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 fixed
to 50mm.
The LCD panel will also display <O> mm.
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.
