Autofocus can fail to achieve focus (the focus confirmation light  
blinks) with certain subjects such as the following:
Subjects difficult to focus
  Very low-contrast subjects
(Example: Blue sky, solid-color walls, etc.)
  Subjects in very low light
  Extremely backlit or reflective subjects
(Example: Car with a highly reflective body, etc.)
  Near and far subjects covered by an AF point 
(Example: Animal in a cage, etc.)
  Repetitive patterns
(Example: Skyscraper windows,  computer keyboards, etc.)
In such cases, do one of the following:
(1) With One-Shot AF, focus an obje ct at the same distance as the 
subject and lock the focus before recomposing (p.48).
(2) Set the lens focus mode switch to  and focus manually.
When Autofocus Fails
 If an Extender (sold separately) is at tached and the maximum aperture of 
the lens is f/5.6 or smaller (larg er f/number), AF will not be possible 
(except Live mode/ u Live mode AF). For deta ils, see the Extender’s 
instruction manual.
  For situations where AF  can fail to achieve focus with Live mode/ u Live 
mode AF, see page 117.

Remote Control Shooting
This remote switch has a 60 cm/2.0 feet cord and enables you to press 
the shutter button halfway or comple tely. It connects to the camera’s 
remote control terminal.

cover (p.23) attached to the camera strap.
During Live View shooting and  movie shooting, attaching the 
eyepiece cover is unnecessary.
1Remove the eyecup.
 Push the bottom of the eyecup 
upward.

Basically operates like a built-in flash for easy operation.
When an EX-series Speedlite (sold separately) is attached to the 
camera, almost all the autoflash control is done by the camera. In other 
words, it is like a high-output flash  attached externally in place of the 
built-in flash.
For detailed instructions, see the EX-series Speedlite ’s instruction 
manual. This camera is a Type-A camera that can use all the features 
of EX-series Speedlites.
External Speedlites
EOS-dedicated, EX-series Speedlites
Shoe-mount Speedlites Macro Lites
 With an EX-series Speedlite not compatible with  flash function settings 
(p.147), only [ Flash exp. comp ] and [E-TTL II meter. ] can be set for 
[ External flash func. setting ]. (Certain EX-series Speedlites also 
enable [ Shutter sync.] to be set.)
  If flash exposure compensation is se t with the external Speedlite, the 
flash exposure compensation icon  displayed on the camera’s LCD 
monitor will change from y  to  .
  If the flash metering mode is set to  TTL autoflash with the Speedlite’s 
Custom Function, the flash w ill fire at full output only.
COPY  
						

							207
External Speedlites
 With an EZ/E/EG/ML/TL-series Speedlite set in TTL or A-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 adjust the aperture setting before 
shooting.
  When using a Speedlite which has  manual flash mode, shoot in the 
manual flash mode.
Sync Speed
The camera can synchronize with compact, non-Canon flash units at 
1/200 sec. or slower. Be sure to te st the flash unit beforehand to make 
sure it synchronizes properly with the camera.
Cautions for Live View shooting
A non-Canon flash will not fire  during Live View shooting.
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 might 
not fire.
