  Since bulb exposures produce more  noise than usual, the image might 
look rough or grainy.
  For bulb exposures, using Remote Switch RS-80N3 or Timer Remote 
Controller TC-80N3 (both sold separately) is recommended.
  When C.Fn II -1 [ Long exp. noise reduction ] is set to [1:Auto] or 
[ 2:On ], noise generated by the bulb  exposure can be reduced. (p.163)

Bulb Exposures
If your eye is not looking at the 
viewfinder, stray light entering the 
eyepiece can adversely affect the 
exposure. To prevent this, slide the 
eyepiece shutter lever as shown by the 
arrow to shutter the eyepiece.
You can connect Remote Switch RS-80N3 or Timer Remote Controller 
TC-80N3 (both sold separately) or any EOS accessory equipped with 
an N3-type terminal to the camera and shoot with it.
To operate the accessory, refer to its instruction manual.
1Open the terminal cover.
  Open the upper cover.
2Connect the plug to the remote 
control terminal.
 Connect the plug as shown in the 
illustration.

Although using the self-timer or Remote Switch can prevent camera 
shake, using mirror lockup to prevent camera vibrations can also help 
when you use a super telephoto lens or shoot close ups.
When C.Fn III -15 [Mirror lockup] is set to [1:Enable] or [2:Enable: 
Down with SET]  (p.172), shooting with mirror lockup is possible.
1 Focus the subject, press the shutter button completely 
and release it.
X The mirror will lockup and < 2> will blink on the top LCD panel.
2 Press the shutter button completely again.
XThe picture will be taken.
  With [ 1] set, the mirror will go back down when the picture is 
taken.
  With [ 2] set, the mirror lockup will remain even after the picture is 
taken. To cancel the mirror lockup, press < 0>.
Mirror Lockup
  In very bright light such as at the beach or ski slope on a sunny day, take 
the picture promptly after mirror lockup.
  During mirror lockup, do not point the camera lens at the sun. The sun’s 
heat can scorch and damage the shutter curtains.
  If you use bulb exposures, the self-timer, and mirror lockup in 
combination, keep pressing the shutter button completely (self-timer 
delay time + bulb exposure time). If you let go of the shutter button 
during the 10-sec./2-sec. self-timer countdown, there will be a shutter-
release sound. This is not the actual  shutter release (no picture is taken).
 When [ 1:Enable ] is set, single shooting will take effect even if the drive 
mode is continuous. When [ 2:Enable: Down with SET] is set, the 
current drive mode will take effect for the shooting.
  When the self-timer is set to < k> or < l>, the picture will be taken 
after 10 sec. or 2 sec. respectively.
  The mirror locks up, and after 30 seconds, it will go back down 
automatically.
  For mirror lockup shots, using Remote Switch RS-80N3 or Timer Remote 
Controller TC-80N3 (both sold separately) is recommended.

An EX-series Speedlite (sold separately) makes flash photography as 
easy as normal shooting without flash. You can easily do the flash 
operations below. For detailed instructions, see the EX-series 
Speedlite’s instruction manual.
   E-TTL II Autoflash
E-TTL II is an autoflash exposure  system incorporating improved 
flash exposure control and lens  focusing distance information, 
making it more precise than the pr evious E-TTL system (evaluative 
flash metering with preflash). The camera can execute E-TTL II 
autoflash with any EX-series Speedlite.
 • High-Speed Sync (FP flash)
With high-speed sync, you can set  a flash sync speed faster than 1/
250 sec.
 • FE (Flash Exposure) Lock
Press the camera’s < I> button to lock the flash exposure at the 
desired part of the subject.
 • Flash Exposure Compensation
In the same way as normal exposure compensation, you can set 
exposure compensation for flash. You can set the flash exposure 
compensation up to ±3 stops in 1/3-stop increments.
With the camera, set it by pressing <
Q> and turning the  dial.
 • FEB (Flash Ex posure Bracketing)
The flash output is changed automatic ally for three successive shots 
(only with FEB-compatible Speedlites). Set flash exposure 
bracketing up to ±3 stops in 1/3-stop increments. During FEB 
shooting, the < r> icon will blink in the viewfinder.
 • E-TTL II Wireless Autoflash with Multiple Speedlites
As with wired, multiple Speedlites, wireless E-TTL II autoflash with 
multiple Speedlites (those compatible  with wireless flash) provides 
all the above features. Sophisticated lighting effects can be obtained 
since connection cables are unnecessary.

3 Flash Function Settings and Flash Custom Functions
When an EX-series Speedlite (such as  the 580EX II) controllable by the camera is attached, you can use the camera’s menu screen to set the 
Speedlite’s flash function settings such  as the flash mode, FEB, and 1st 
or 2nd curtain sync, and wireless fl ash. Flash Custom Functions can 
also be enabled or disabled.
Turn on the Speedlite before setting its functions.
For details on which Speedlite settings the camera can set, see the EX-
series Speedlite’s instruction manual.
1Select [External Speedlite 
control].
  Under the [ 6] tab, select [ External 
Speedlite control ], then press .
2Select either [F lash function 
settings] or [Flash C.Fn settings].
  Turn the < 5> dial to select the menu 
item, then press < 0>.
3Set the flash function settings.

desired. The procedure is the same 
as setting a menu function.
  On the flash function settings screen, 
the settable items, current settings, 
flash mode setting, and flash Custom 
Function settings might look different 
on your camera.
  To reset the flash settings to the 
default, press the < B> button 
while the flash function setting screen 
is displayed.

Metered Manual Flash ExposureThis is for close-up flash photography when you want to set the flash level 
manually. Use an 18% gray card and an EX-series Speedlite which has 
manual flash mode. Follow the instructions below:
1. Set the camera and Speedlite settings. • Set the camera’s shooting mode < a> or < f>.
• Set the Speedlite to manual flash mode.
2. Focus the subject. • Focus manually.
3. Set up the 18% gray card. • Place the gray card at the subject’s position.
• In the viewfinder, the entire spot metering circle at the center should cover the gray card.
4. Press the < I> button. ( 8)
5. Set the flash exposure level. • Adjust the Speedlite’s manual flash level and the camera aperture so that the flash exposure level aligns with the 
standard exposure index.
6. Take the picture. • Remove the gray card and take the picture.
  If flash exposure compensation has already been set with the Speedlite, 
you cannot use the camera’s < Q> button or Flash function settings 
menu to set flash exposure compensati on. If it is set with both the 
camera and Speedlite, the Speedlite’s setting overides the camera’s.
  If autofocus cannot be achieved, the external, EOS-dedicated 
Speedlite’s AF-assist beam (if the Speedlite has it) will be emitted 
automatically.
  If focus cannot be achieved with the external Speedlite’s AF-assist 
beam, select the center AF point. With some external Speedlites, 
autofocus with AF-assist beam works only with the center AF point.
  This camera is a Type-A camera that can use all the features of EX-
series Speedlites.
  The flash function’s [ E-TTL II] setting will work together with C.Fn II -4 
(p.164). And [ Flash firing] will work with C.Fn II -6 (p.165).
  Only [ E-TTL II ] and [Flash exp. comp ] can be settable for flash function 
settings with an EX-series Speedlite not controllable by the camera. 
(For some EX-series Speedlites, [ Shutter sync.] can also be settable.)

Flash Photography
 With an EZ/E/EG/ML/TL-series Speedlite set in the TTL or A-TTL 
autoflash mode, the flash can be fired at full output only.
 Set the 
camera’s shooting mode to manual or aperture-priority AE and shoot.
  When using a Speedlite which has m anual flash mode, shoot in the 
manual flash mode.
  With an EX-series Speedlite set to TTL autoflash with the flash’s 
Custom Function, the flash will fire at full output only.
Sync Speed
The camera can synchronize with non-Canon compact flash units at 
1/250 sec. and slower speeds. With large studio flash units, since the 
flash duration is longer, set the sy nc speed within 1/30 sec. to 1/125 
sec. Be sure to test the flash synchronization before shooting.
PC Terminal
  The camera’s PC terminal is provided 
for flash units having a sync cord. The 
PC terminal is threaded to prevent 
inadvertent disconnection.
  The camera’s PC terminal has no 
polarity. You can connect any sync 
cord regardless of its polarity.
Using Non-EX-series Canon Speedlites
Using Non-Canon Flash Units
  If the camera is used with a flash unit or flash accessory dedicated to 
another camera brand, the camera may not operate properly and 
malfunction may result.
  Also, do not connect to the camera’s PC terminal any flash unit requiring 
250 V or more.
  Do not attach a high-voltage flash unit on the camera’s hot shoe. It might 
not work.
A flash unit attached to the camera’s hot shoe and a flash unit connected to 
the PC terminal can both be used at the same time.

Live View Shooting
You can shoot while viewing a real-time image on the 
camera’s LCD monitor or on a personal computer 
screen. This is called “Live View shooting.”
 Using a hard disk-type card is not recommended. Use a 
memory card.
  When you use Live View shooting for a long period, the 
camera’s internal temperature may increase and it can degrade 
image quality. Terminate Live View shooting when not shooting 
images.
  For a long exposure, stop Live View shooting temporarily and 
wait several minutes before shooting.
  If the  < > (warning for high temperature in the camera) icon is 
displayed, terminate Live View shooting.
  With a hard-disk type card in the camera, if Live View shooting 
continues while the < > icon is  displayed, the Live View might 
stop automatically. Live View shooting will be disabled until the 
camera’s internal temperature decreases.

Instead of looking through the viewfinder, you can look at a real-time 
image on the camera’s LCD monitor while shooting. You can also 
magnify the real-time image on the LCD monitor by 5x or 10x so you 
can focus more precisely. Convenient when the camera is mounted on 
a tripod for shooting still lifes, for example.
1Set the lens focus  mode switch to 
< g >.
 During Live View shooting, 
autofocusing is not possible .
2Select [Live View function 
settings].
 Under the [ 6] tab, select [ Live View 
function settings ], then press .
3Select [Live View shoot.].
  Turn the < 5> dial to select [ Live 
View shoot. ], then press < 0>.
4Select [Enable].
  Turn the < 5> dial to select [ Enable], 
then press < 0>.
Live View Shooting
Preparing for Live View Shooting
During Live View shooting, do not point the camera toward the sun. The 
sun’s heat can damage the camera’s internal components.
If you handhold the camera like a compact digital camera and shoot while 
viewing the LCD monitor, camera shake can cause blurred images. For Live 
View shooting,  mounting the camera on a tripod is recommended .
About Remote Live View ShootingWith the provided software installed in the personal computer, you can connect the camera to 
the personal computer and shoot remotely while viewing the computer screen instead of the 
camera’s viewfinder. For details, see the Software Instruction Manual in the CD-ROM.
