3 Setting Speedlite Functions N
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 1/200 
sec. to 30 sec. to suit the scene’s brightness. High-speed sync is 
also possible.
 : 1/200-1/60 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.
 : 1/200 sec. (fixed)
The flash-sync speed is fixed at 1/200 sec. This more effectively 
prevents subject blur and camera shake than with [ 1/200-1/60 sec. 
auto ]. However, in low light, the subject’s background will come out 
darker than with [ 1/200-1/60 sec. auto ].
[Flash sync. speed in Av mode]
If [1/200-1/60 sec. auto ] or [1/200 sec. (fixed) ] is set, high-speed sync is 
not possible in the < f> mode.

3 Setting Speedlite Functions N
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 2nd curtain synchronization, two flashes will be fired: 
Once when you press the shutter button completely, and once 
immediately before the exposure ends. Also, with shutter speeds 
faster than 1/30 sec., 1st curtain synchronization will automatically 
take effect.
You can also select [ High-speed synchronization ] (e ). For 
details, refer to the Speedlite’s instruction manual.
 Wireless functions
Wireless flash shooting with multiple Speedlites is possible with 
optical or radio transmissions. For details, see the wireless 
Speedlite’s instruction manual (for Speedlite 90EX, etc.).
 Flash exposure compensation
See “Flash Exposure Compensation” on page 154.
 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.
 [Manual flash ] is for advanced users 
who want to set the [ Flash output 
level ] (1/1 to 1/128) themselves.
 Regarding other flash modes, refer to 
your Speedlite’s instruction manual.

When you switch the power to  or < 2> (or Camera auto off), 
the Self Cleaning Sensor Unit will operate automatically to remove dust 
on the image sensor. Normally, you need not pay attention to this 
operation. You can also activate or stop the Self Cleaning Sensor Unit 
when necessary.
1Select [Sensor cleaning].
 Under the [5 3] tab, select [ Sensor 
cleaning ], then press < Q/0 >.
2Select [Clean nowf].
Select [ Clean now f], then press 
< Q /0 >.
 On the dialog screen, select [ OK] and 
press < Q/0 >.
The screen will indicate that the 
sensor is being cleaned. Although 
there will be a shutter sound, a 
picture is not taken.
The sensor cleaning also works while 
no lens is attached. If no lens is 
attached, do not insert your finger or 
blower tip beyond the lens mount. 
This is to prevent damage to the 
shutter curtains.
 The camera will restart.
f  Automatic Sensor Cleaning
Cleaning the Sensor Now
For best results, perform the sensor cleaning with the camera placed 
upright and stable on a table or other flat surface.
 Even if you repeat the sensor  cleaning, the result will not improve much. 
Immediately after the sensor cleaning is finished, the [ Clean now
f] 
option will remain disabled temporarily.

In step 2, select [ Auto cleaningf] and set it to [ Disable].
Dust that could not be removed by the automatic sensor cleaning can 
be removed manually with a blower, etc. Before cleaning the sensor, 
detach the lens from the camera.
The surface of the image sensor is extremely delicate. If the 
sensor needs to be cleaned directly, having it done by a Canon 
Service Center is recommended.
1Set the power to < 2>.
2Detach the lens.
3Clean the sensor.
4End the cleaning.
Disabling Automatic Sensor Cleaning
Manual Sensor Cleaning
The surface of the image sensor is extremely delicate. Clean the sensor 
with care.
 Use a plain blower without any brush attached. A brush can scratch the 
sensor.
 Do not insert the blower tip inside the camera beyond the lens mount. It 
can damage the shutter curtains.
 Never use canned air or gas to clean the sensor. The blowing force can 
damage the sensor or the spray gas can freeze on the sensor.
 If a smudge that cannot be removed with a blower remains, having the 
sensor cleaned by a Canon Service Center is recommended.

Normally, the Self Cleaning Sensor Unit will eliminate most of the dust 
that may be visible on captured images. However, in case visible dust 
still remains, you can append the Dust Delete Data to the image for 
erasing the dust spots later. The Dust Delete Data is used by Digital 
Photo Professional (provided software, p.340) to erase the dust spots 
automatically.
Prepare a solid white object such as a sheet of paper.
 Set the lens focal length to 50 mm or longer.
 Set the lens focus mode switch to < MF> and set the focus to infinity 
( ∞ ). If the lens has no distance scale, look at the front of the lens and 
turn the focusing ring clockwise all the way.
1Select [Dust Delete Data].
 Under the [A 4] tab, select [Dust 
Delete Data ], then press < Q/0 >.
2Select [OK].
Select [ OK] and press < Q/0 >. 
After the automatic self-cleaning of 
the sensor is performed, a message 
will appear. Although there will be a 
shutter sound during the cleaning, a 
picture is not taken.

3Photograph a solid-white object.
At a distance of 20 cm - 30 cm (0.7 ft. 
- 1.0 ft.), fill the LCD monitor with a 
patternless, solid-white object and 
take a picture.
The picture will be taken in aperture-
priority AE mode at an aperture of f/22.
Since the image will not be saved, the 
data can still be obtained even if there 
is no card in the camera.
When the picture is taken, the camera 
will start collecting the Dust Delete 
Data. When the Dust Delete Data is 
obtained, a message will appear.
Select [OK], and the menu will reappear.
If the data was not obtained 
successfully, a message to that effect 
will appear. Follow the “Preparation” 
procedure on the preceding page, then 
select [
OK]. Take the picture again.
After the Dust Delete Data is obtained, it is appended to all the JPEG 
and RAW images captured thereafter. Before an important shoot, it is 
recommended to update the Dust Delete Data by obtaining it again.
For details about using Digital Photo Professional (provided software, 
p.340) to erase dust spots, refer to the PDF Software Instruction   
Manual on the DVD-ROM.
The Dust Delete Data appended to the image is so small that it hardly 
affects the image file size.
About the Dust Delete Data
Be sure to use a solid-white object such as a new sheet of white paper. If the 
paper has any pattern or design, it may be recognized as dust data and 
affect the accuracy of the dust deletion with the software.

Image Playback
This chapter explains functions related to viewing 
photos and movies, in more detail than in Chapter 2 
“Scene Intelligent Auto + Basic Zone Modes and Image 
Playback”. Here you will find explanations of how to 
play back and erase photos and movies with the 
camera and view them on a TV set.
About images shot and saved with another deviceThe camera may not be able to properly display images captured
