amount.
  To make the flash exposure brighter,

[ Disable ], the image may look bright even  if a decreased flash exposure 
compensation is set.
  If flash exposure compensation is se t with an external Speedlite (sold 
separately, p.193), you cannot set th e flash exposure compensation with 
the camera (Quick Control or External flash function settings). If it is set 
with both the camera and Speedlite, the Speedlite’s setti ng overrides the 
camera’s.
  The exposure compensation  amount will remain in effect even after you 
set the power switch to < 2>.
  You can also set flash expo sure compensation with [Built-in flash 
settings ] in [z2: Flash control ] (p.195).
  The camera can also be used to set the external Speedlite’s flash 
exposure compensation in the same  way as with the built-in flash.

Flash photography with EX-series Speedlite (sold separately) is as easy 
as with built-in flash.
For detailed instructions, refer to the EX-series Speedlite’s 
instruction manual.  This camera is a Type-A camera that can use all 
the features of EX-series Speedlites.
To set the flash functions and flash Custom Functions with the camera’s 
menu, see pages 195-202.
  Flash exposure compensation
Set it with the Quick Control screen (p.50) or [ External flash func. 
setting ] under [ z2: Flash control ] (p.199). With the Quick Control 
screen, you can set flash exposure  compensation in the same way 
as for the built-in flash. See page 190.
  FE lock
Set this in the same way as for the built-in flash. See steps 2 to 4 on

  With an EZ/E/EG/ML/TL-series Speedlite set to A-TTL or TTL 
autoflash mode, the flash can be  fired at full output only.
Set the camera’s shooting mode to < a> (manual exposure) or 
< f > (aperture-priority AE) and adju st the aperture setting before 
shooting.
  When using a Speedlite that has manual flash mode, shoot in the 
manual flash mode.
Sync Speed
The camera can synchronize with  non-Canon compact flash units at 
1/250 sec. and slower speeds. With large studio flash units, be sure to 
test the flash synchronization befor e shooting with the sync speed set 
within approx. 1/60 sec. to 1/30 sec., since the flash duration of such \
units is longer than that of comp act flash units and vary depending on 
the models.
Cautions for Live View Shooting
If you use a non-Canon flash unit with Live View shooting, set [ A2: 
Silent LV shoot. ] to [Disable] (p.231). The flash will no t fire if it is set to 
[Mode 1] or [Mode 2].
Canon Speedlites Other Than the EX-series
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.
  Do not attach a high-voltage flash un it on the camera’s hot shoe. It may 
not fire.

With the built-in flash or an EX-series Speedlite compatible with flash 
function settings, you can use the camera’s menu screen to set flash 
functions and the external Speedlite’s Custom Functions.  If you use an 
external Speedlite, attach the Spee dlite to the camera and turn on 
the Speedlite before setting the flash functions.
For details on the external Speedlit e’s flash functions, refer to the 
Speedlite’s instruction manual.
1Select [Flash control].
 Under the [ z2] tab, select [Flash 
control ], then press < 0>.
X The Flash control screen will appear.
2Select the desired option.
  Select the option to be set, then press 
.
To enable flash photography, set 
[Enable]. To enable only the AF-assist 
beam, set [Disable].
For normal flash exposures, set it to 
[Evaluative ]. If [Average ] is set, the 
flash exposure will be averaged for the 
entire metered scene. Flash exposure 
compensation may be necessary. This 
setting is for advanced users.

You can set the flash sync speed for 
flash photography in the aperture-priority 
AE (f) mode.
  : Auto
The flash sync speed is set automatically within a range of 1/250 
sec. to 30 sec. to suit the scene’s brightness. High-speed sync is 
also possible.
  : 1/250-1/60 sec. auto
Prevents a slow shutter speed from  being set in low-light conditions. 
It is effective for preventing subject blur and camera shake. 
However, while the subject will be properly exposed with the flash, 
the background may come out dark.
  : 1/250 sec. (fixed)
The flash sync speed is fixed at 1/ 250 sec. This more effectively 
prevents subject blur and camera shake than with [ 1/250-1/60sec. 
auto ]. However, in low light, the subject’s background will come out 
darker than with [ 1/250-1/60sec. auto].
Flash Synchronization Speed in Av Mode
If [1/250-1/60sec. auto ] or [1/250 sec. (fixed)] is set, high-spe ed sync is not 
possible in the  mode with the external Speedlite.

3 Setting the FlashN
 Flash mode
Normally, set this to [E-TTL II ]. This 
enables autoexposure shooting with the 
built-in flash.
To set the flash output level manually, 
select [Manual flash ].
Select [2 flash output ], then set the 
flash output level to within 1/1 - 1/128 
(1/3-stop increments) before shooting.
  Shutter synchronization
Normally, set this to [1st curtain] so that 
the flash fires immediately after the 
exposure starts.
If [ 2nd curtain ] is set, the flash will fire right before the shutter closes. 
When this is combined with a slow shutter speed, you can create a trail 
of light such as from car headli ghts at night. With second-curtain 
synchronization, two flashes will be fired: once when you press the 
shutter button completely, and once immediately before the exposure 
ends.
Built-in Flash Settings
When using second-curtain synchronizat ion, set the shutter speed to 1/25 
sec. or slower. If the sh utter speed is 1/30 sec. or faster, first-curtain 
synchronization will be used  automatically even if [2nd curtain] is set.

3 Setting the FlashN
The screen display and setting  options will differ depending on the 
external Speedlite model, current flash mode, Speedlite’s Custom 
Function settings, etc.
For details on your Speedlite’s flash  functions, refer to the Speedlite’s 
instruction manual.
Sample display
 Flash mode
You can select the flash mode to suit your desired flash shooting.
[E-TTL II flash metering] is the standard 
mode of EX-series Speedlites for 
automatic flash shooting.
The [Manual flash ] mode is for setting 
the Speedlite’s [ Flash output level] 
yourself.
Regarding other flash modes, refer to the 
instruction manual of a Speedlite 
compatible with the functions.

 Wireless functions
Wireless (multiple) flash shooting is 
possible with radio or optical 
transmission. For details on wireless 
flash, refer to the instruction manual of a 
Speedlite compatible with the wireless 
flash shooting.
  Flash zoom (Flash coverage)
With Speedlites having a zooming flash 
head, you can set the flash coverage. 
Normally, set this to [AUTO] so that the 
camera will automatically set the flash 
coverage to match the lens focal length.
  Shutter synchronization
Normally, set this to [First-curtain 
synchronization] so that the flash fires 
immediately after the exposure starts.
If [ Second-curtain synchronization ] is set, the flash will fire right 
before the shutter closes. When this  is combined with a slow shutter 
speed, you can create a trail of light such as from car headlights at 
night. With second-curtain synchronization, two flashes will be fired: 
once when you press the shutter button completely, and once 
immediately before the exposure ends.
If [ High-speed synchronization] is set, the flash can be used at all 
shutter speeds. This is especially ef fective for portraits using fill flash 
when you want to give priority to the aperture setting.
