i Selecting the Drive Mode
 If  or < M> is set, the time lag from when you press the shutter 
button completely until the picture is shot will be longer than with normal 
single or continuous shooting.
 With Live View shooting, < B> and  cannot be set.
 When the battery level is low, the continuous shooting speed may 
become slightly slower.
 In AI Servo AF operation, the continuous shooting speed may become 
slightly slower depending on the  subject and the lens used.
 i: The maximum continuous shooting speed of approx. 5.0 shots/sec. 
is attained under the following conditions*: At 1/500 sec. or faster shutter 
speed, at maximum aperture (varies depending on the lens), Distortion 
correction: Disable, and Anti-flicker  shooting: Disable. The continuous 
shooting speed may decrease depending on the shutter speed, aperture, 
subject conditions, brightness, lens,  flash use, temperature, remaining 
battery level, etc.
* Set the AF operation mode to One-Shot AF and the Image Stabilizer (IS) switch to 
OFF when using the following lenses: EF300mm f/4L IS USM, EF28-135mm f/3.5-
5.6 IS USM, EF75-300mm f/4-5.6 IS USM, and EF100-400mm f/4.5-5.6L IS USM.

1Press the  button.
[Drive mode ] will appear.
2Select the self-timer.
Press the < Y> < Z> keys to select 
the self-timer, then press < 0>.
Q :10-sec. self-timer
The remote controller can also 
be used (p.350).
l :2-sec. self-timer (p.75)
q :
10-sec. self-timer plus continuous shots
Press the   keys to set 
the number of multiple shots (2 to 
10) to be taken with the self-timer. 
3Take the picture.
 Look through the viewfinder, focus on 
the subject, then press the shutter 
button completely.

You can check the self-timer operation with 
the self-timer lamp, beeper, and countdown 
display (in seconds) on the LCD monitor.
 Two sec. before the picture is taken, the self-timer lamp will light up 
and the beeper will sound faster.
j Using the Self-timer
 With < q>, the interval between the multiple shots may be prolonged 
depending on the shooting functions settings such as the image-
recording quality or flash.
 If you do not look through the viewfinder when you press the shutter 
button, attach the eyepiece cover (p.351). If stray light enters the 
viewfinder when the picture is taken, it may throw off the exposure.
After taking self-timer shots, playing back the image (p.97) to check 
focus and exposure is recommended.
 When using the self-timer to shoot yourself, use focus lock (p.69) on an 
object at the same distance as where you will stand.
 To cancel the self-timer after it starts, either touch the LCD monitor or 
press the < YQi> button.

3 Setting the Image-Recording Quality
* The file size, possible shots, and maximum burst during continuous shooting are 
based on Canon’s testing standards (3:2 aspect ratio, ISO 100 and Standard 
Picture Style) using an 8 GB card.  These figures will vary by the subject, 
card brand, aspect ratio, ISO speed, Picture Style, Custom Functions, and 
other settings.
* Figures in parentheses apply to an UHS-I compatible 8 GB card based on  Canon’s testing standards.

I want to select the image-recording quality matching the paper 
size for printing.
Refer to the diagram on the left when 
choosing the image-recording quality. If 
you want to crop the image, selecting a 
higher quality (more pixels) such as  73, 
83 , 1+ 73, or 1  is recommended.
b  is suitable for playing back the image 
with a digital photo frame.  c is suitable 
for emailing the image or using it on a 
Web site.
 What’s the difference between 
7 and 8?
These settings indicate the different levels of image quality caused 
by different compression rates. The 
7 setting produces a higher 
image quality with the same number of pixels. Although 
8 produces 
a slightly lower image quality, this  allows more images to be saved 
on the card. Both  b and c  have 7 (Fine) quality.
 I was able to take more shots than the number of possible shots 
indicated.
Depending on the shooting conditions, you may be able to take 
more shots than is indicated. It may also be fewer than indicated. 
The number of possible shots  displayed is only approximate.
 Does the camera display the maximum burst?
The maximum burst is displayed on the viewfinder’s right side. Since 
it is only a single-digit indicator  0 - 9, any number higher than 8 will 
be displayed only as “ 9”. Note that this number will also be displayed 
even when no card is installed in the camera. Be careful not to shoot 
without a card in the camera.
 When should I use 
1?
1 images must be processed on a computer. For details, see 
“ 1 ” and “ 1+73 ” on the next page.

1 is the raw image data before it is made into  73 or other images. 
1  images cannot be viewed on a computer without the use of EOS 
software, such as Digital Photo Prof essional (p.404). However, you can 
perform various adjustments on them that are impossible with other 
image types such as  73. 1 is effective when you want to precisely 
adjust the image yourself or shoot an important subject.
1 +73  records a  1 image and a  73 image with a single shot. The 
two images are saved to the card si multaneously. The two images will 
be saved in the same folder with the same file numbers (file extension 
.JPG for JPEG and .CR2 for RAW). 73  images can be viewed or 
printed even with a computer which does not have the EOS software 
installed.

RAW Image Processing Software
 To display RAW images on a computer, using Digital Photo Professional 
(DPP, EOS software, p.404) is recommended.
 Previous DPP Ver.4.x cannot proc ess RAW images taken with this 
camera. If your computer has the previous DPP Ver.4.x, update it with 
the EOS DIGITAL Solution Disk. (The previous version will be 
overwritten.) Note that DPP Ver.3.x or earlier cannot process RAW 
images taken with this camera.
 Commercially-available software may not be able to display RAW 
images taken with this camera. For co mpatibility information, contact the 
software manufacturer.

You can change the image’s aspect ratio. [3:2] is set by default. When 
[4:3 ], [16:9 ], or [ 1:1] is set, lines will appear to indicate the shooting 
range. During Live View shooting, the image appears with the 
surrounding area masked in black.
1Select the aspect ratio.
 Under the [z 3] tab, select [Aspect 
ratio ], then press < 0>.
 [Aspect ratio ] will appear.
2Set the aspect ratio.
Select an aspect ratio, then press 
.
 JPEG images
The images will be saved with the set aspect ratio.
 RAW images
The images will always be saved with the [ 3:2] aspect ratio. The 
selected aspect ratio information is added to the RAW image file. 
When you process the RAW image with the EOS software, this 
allows you to generate an image with the same aspect ratio that was 
set for shooting. In the case of the [ 4:3], [16:9 ], and [ 1:1] aspect 
ratios, the lines to indicate the aspect ratio will appear during image 
playback, but they are not actually drawn on the image.
