 Set the lens focus mode switch to < AF> (p.40).
  To prevent camera shake, press t he shutter button gently (p.44, 45).
  If the lens has an Image Stabilizer, set the IS switch to < 1>.
  In low light, the shutter speed may  become slow. Use a faster shutter 
speed (p.160), set a higher ISO speed  (p.120), use flash (p.188, 193), 
or use a tripod.
  Set the AF operation to One-Shot AF . Focus lock is not possible in the 
AI Servo AF mode, or when servo ta kes effect in AI Focus AF mode 
(p.75).
  If the AF method is set to [ u+Tracking ], [FlexiZone - Multi], or 
[ FlexiZone - Single ] for Live View shooting or movie shooting, the AF 
control method (phase-difference detection with the image sensor or 
contrast detection) will switch automatically depending on the lens 
used and functions selected, such as  movie digital zoom or magnified 
view. This can greatly affect the  AF speed and the camera may take a 
longer time to focus.
  Depending on the shooting conditions, it  may take longer to focus the 
subject. Use FlexiZone - Single or focus manually.
  Depending on the shutter speed, aperture, subject conditions, 
brightness, etc., the continuous  shooting speed may become slower.
  If you shoot something that has fine  detail (such as a field of grass), 
the file size will be larger and the actual maximum bur st may be lower 
than the number mentioned on page 117.
The image is out of focus.
I cannot lock the focus and recompose the shot.
AF speed changes depending on lenses used.
With FlexiZone - Multi, it takes longer to focus.
The continuous shooting speed is slow.
The maximum burst during continuous shooting is lower.

 When [ z4: Highlight tone priority ] is set to [Disable], ISO 100/125/
160 can be set (p.145).
  If [z 4: Highlight tone priority ] is set to [Enable], the settable ISO 
speed range will be ISO 200 - ISO 12800  (or up to ISO 6400 for movie 
shooting). Even if you expand th e settable ISO speed range in [ISO 
speed range ], you cannot set ex panded ISO speeds (H).
  If [z 4: Highlight tone priority ] is set to [Enable], the Auto Lighting 
Optimizer cannot be set. When [ z4: Highlight tone priority] is set to 
[ Disable ], then the Auto Lighting Optimizer can be set (p.145).
  Set [ z3: Auto Lighting Optimizer ] to [Disable ]. When [ Low/
Standard/High ] is set, even if you set a decreased exposure 
compensation or flash exposure co mpensation, the image may come 
out bright (p.140).
  When the image-recording quality is set to  41 or 61, the 
multiple-exposure image will be recorded in  1 quality (p.181).
  If you shoot at night when the ba ckground is dark, the shutter speed 
becomes slow automatically (slow- sync shooting) so that both the 
subject and background are properly  exposed. To prevent a slow 
shutter speed, under [ z2: Flash control], set [Flash sync. speed in 
Av mode ] to [1/250-1/60sec. auto ] or [1/250 sec. (fixed) ] (p.196).
ISO 100 cannot be set. ISO speed expansion cannot be selected.
The Auto Lighting Optimizer cannot be set.
Even though I set a decreased exposure compensation, 
the image comes out bright.
The multiple-exposure image is shot in  1 quality.
When I use the < f> mode with flash, 
the shutter speed becomes slow.

Troubleshooting Guide
 In shooting modes (< A>< 6>) whose default setting 
is < a> (Auto flash), the built-in flas h will rise automatically when 
necessary.
  If you shoot continuously  with the built-in flash at short intervals, the 
flash may stop operating to protect the flash unit.
  If you use a non-Canon flash unit  with Live View shooting, set [A2: 
Silent LV shoot. ] to [Disable ] (p.231).
  If you use a flash unit other than an  EX-series Speedlite, the flash will 
always be fired at  full output (p.194).
  When the external Speedlite’s [ Flash metering mode] Custom 
Function is set to [TTL ] (autoflash), the flash will always be fired at full 
output (p.202).
  If flash exposure compensation has already been set with the external 
Speedlite, flash exposure com pensation cannot be set with the 
camera. When the external Speedlit e’s flash exposure compensation 
is canceled (set to 0), flash ex posure compensation can be set with 
the camera.
  Under [ z2: Flash control ], set [Flash sync. speed in Av mode ] to 
[ Auto ] (p.196).
  The built-in flash’s pop-up mechanism  moves slightly. This is normal 
and not a malfunction.
The built-in flash is  raised by itself.
The built-in flash does not fire.
The external flash does not fire.
The external flash always fires at full output.
Flash exposure compensation cannot  be set for the external Speedlite.
High-speed sync cannot be set in the < f> mode.
The camera makes a noise when it is shaken.

 If you use flash, the shutter will ma ke two sounds each time you shoot 
(p.217).
  It indicates that the camera’s intern al temperature is high. If the white 
< > icon is displayed, the still ph oto’s image quality may deteriorate. 
If the red < E> icon is displayed, it indicates that the Live View or 
movie shooting will soon stop  automatically (p.249, 287).
  If [53: Wi-Fi ] is set to [Enable], movie shooting is not possible. Before 
shooting movies, set [ Wi-Fi] to [Disable ].
  If the card’s writing speed is  slow, movie shooting may stop 
automatically. If the compression method is set to [ IPB], use a card 
with a reading/writing speed of at  least 6 MB per sec. If the 
compression method is set to [ ALL-I] (I-only), use a card with a 
reading/writing speed of at least 20 MB  per sec. (p.3). To find out the 
card’s reading/writing speed, refer to the card manufacturer’s Web 
site.
  If the movie shooting time reaches  29 min. 59 sec., the movie shooting 
will stop automatically.
  In shooting modes other than , the ISO speed is set 
automatically. In the < a> mode, you can freely set the ISO speed 
(p.257).
The shutter makes two shooting sounds during 
Live View shooting.
During Live View and movie shooting, a white < > or 
red < E> icon is displayed.
I cannot shoot a movie.
Movie shooting stops by itself.

Troubleshooting Guide
 If you shoot a movie when [ Maximum: H (25600)] is set with [ISO 
speed range ] and ISO speed is set to “ H” (25600), the ISO speed will 
switch to “ H” (12800) (during movie shooting with manual exposure). 
Even if you switch back to still photo shooting, the ISO speed will not 
revert to the original setting.
  If you change the shutter speed or  aperture during movie shooting, the 
changes in the exposure may be recorded.
  Zooming the lens during movie s hooting can cause changes in the 
exposure regardless of whether the  lens’ maximum aperture changes 
or not. The changes in the expos ure may be recorded as a result.
  If you move the camera to the left  or right quickly (high-speed panning) 
or shoot a moving subject, t he image may look distorted.
  Flickering, horizontal stripes (noise ), or irregular exposures can be 
caused by fluorescent light, LED  bulbs, or other light sources during 
movie shooting. Also, changes in th e exposure (brightness) or color 
tone may be reco rded. In the  mode, a slow shutter speed may 
solve the problem.
  Setting a lower image quality fo r still photos and shooting fewer 
continuous still photos may resolve the problem.
 
Shooting still photos during movie shooting will cause a discrepancy 
between the actual time and time code.  When you want to edit a movie using 
time code, it is recommended not to shoot still photos during movie shooting.
The manually set ISO speed changes when switching to movie shooting.
The exposure changes during movie shooting.
The subject looks distorted during movie shooting.
The image flickers or horizontal  stripes appear during movie shooting.
When I shoot still photos during movie shooting, 
the movie shooting stops.
