Set the lens’s focus mode switch to < AF> (p.47).
 Press the shutter button gently to prevent camera shake (p.49-50).
 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.192), set a higher ISO speed (p.148), use flash (p.228, 233), 
or use a tripod.
 Depending on the attached lens, the number of usable AF points and 
patterns varies. The lenses are categorized into eight groups from A to 
H. Check which group your lens belongs to. Using a lens in Groups E 
to H will have fewer usable AF points (p.130-131).
 Regarding lighting up or blinking of the AF points when you press the 
 button, see page 123.
 The AF points light up in red only when focus is achieved in low-light 
conditions.

Troubleshooting Guide
The continuous shooting speed may become slower depending on the 
shutter speed, aperture, subject conditions, brightness, lens, flash use, 
temperature, battery type, remaining battery level, shooting function 
settings, etc. For details, see page 139.
 Depending on the shooting conditions, it may take longer to focus on 
the subject. Use FlexiZone - Single or focus manually.
 If you shoot something that has fine detail such as a field of grass, the 
file size will be larger, and the actual maximum burst may be lower 
than the number listed on page 143.
 When [z3: Highlight tone priority ] is set to [Disable], ISO100/125/
160 can be set (p.174).
 If [z3: Highlight tone priority ] is set to [Enable], the settable ISO 
speed range will be ISO 200 - ISO 16000 (or up to ISO 12800 for 
movie shooting). Even if you expand the settable ISO speed range in 
[ Range for stills ] or [Range for movies ], you cannot set expanded 
ISO speeds (H).
The continuous shooting speed is slow.
With FlexiZone - Multi, it takes longer to focus.
The maximum burst during continuous shooting is lower.
ISO 100 cannot be set. ISO speed expansion 
cannot be selected.

Set [ z2: Auto Lighting Optimizer ] to [Disable]. When [Low], 
[ Standard ], or [High] is set, even if you set a decreased exposure 
compensation or flash exposure compensation, the image may come 
out bright (p.169).
 When the image-recording quality is set to  41 or 61 , the 
multiple-exposure image will be recorded in  1 quality (p.218).
 If you shoot at night when the background is dark, the shutter speed 
automatically becomes slow (slow-sync shooting) so that both the 
subject and background are properly exposed. To prevent a slow 
shutter speed, under [z1: Flash control ], set [Flash sync. speed in 
Av mode ] to [1/250-1/60sec. auto ] or [1/250 sec. (fixed) ] (p.236).
 In shooting modes (< A>   
) whose default setting is < a> (Auto built-in 
flash firing), the built-in flash will be raised automatically when 
necessary.
 In the < 8: xG > and < v: ABCD > modes, when you 
press the shutter button halfway under low-light conditions, the built-in 
flash may be raised automatically and emit the AF-assist beam.
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  mode with flash, 
the shutter speed becomes slow.
The built-in flash rises by itself. 
						

							487
Troubleshooting Guide
If you use the built-in flash too often in too short a period of time, the 
flash may stop firing for a while to protect the light-emitting unit.
 If you use a non-Canon flash unit with Live View shooting, set [ z6: 
Silent LV shoot. ] to [Disable ] (p.272).
 If you use a flash unit other than an EX-series Speedlite, the flash will 
always be fired at full output (p.234).
 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.243).
 If flash exposure compensation is set with the external Speedlite, flash 
exposure compensation cannot be set with the camera. When the 
external Speedlite’s flash exposure compensation is canceled (set to 
0), flash exposure compensation can be set with the camera.
 Under [ z1: Flash control ], set [Flash sync. speed in Av mode ] to 
[ Auto] (p.236).
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.

Troubleshooting Guide
In shooting modes other than < a>, the ISO speed is set 
automatically. In the < a> mode, you can freely set the ISO speed 
(p.299).
 ISO speed will be set according to the setting for [ Range for stills] 
during viewfinder shooting and Live View shooting, or that for [ Range 
for movies ] during movie shooting with manual exposure.
 If you change the shutter speed or aperture during movie shooting, the 
changes in the exposure may be recorded.
 Zooming the lens during movie shooting may cause changes in the 
exposure regardless of whether the lens’s maximum aperture changes 
or not. The changes in the exposure may be recorded as a result.
 If you move the camera to the left or right quickly or shoot a moving 
subject, the image may look distorted. The problem may be more 
noticeable in time-lapse movie shooting.
 Flickering, horizontal stripes (noise), or irregular exposures can be 
caused by fluorescent lighting, LED lighting, or other light sources 
during movie shooting. Also, changes in the exposure (brightness) or 
color tone may be recorded. In the < a> mode, a slow shutter speed 
may reduce the problem. The problem may be more noticeable in 
time-lapse movie shooting.
The ISO speed cannot be set for 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.
