Using AF to Focus (AF Method)
AF Operation
Even when focus is achieved, pre ssing the shutter button halfway 
will focus again.
 You cannot focus on a moving subject continuously.
 The image brightness may change during and after the AF 
operation.
 Depending on the subject or shoot ing conditions, etc., focusing may 
take longer or the continuous s hooting speed may become slower.
 If the light source changes while the  Live View image is displayed, 
the screen may flicker and focusing may be difficult. If this happens, 
exit Live View shooting and execute AF under the actual light 
source.
 If [u+Tracking ] is set, magnified view is not possible.
 When [FlexiZone - Multi ] is set and you press the < u> button (or 
tap < s> on the screen), the center of the selected zone (or image 
center with automatic selection) will be magnified. If you press the 
shutter button halfway, the display will return to normal and the 
camera will focus.
 When [ FlexiZone - Single ] is set and you press the < u> button (or 
tap < s> on the screen), the area covered by the AF point will be 
magnified. Press the shutter button  halfway to focus in the magnified 
view. This is effective when the  camera is attached to a tripod and 
you need to attain very precise fo cus. If focusing is difficult in 
magnified view, return to the normal display and use AF. Note that 
the AF speed may differ between the normal and magnified views.
 If you magnify the view after focusing with [ FlexiZone - Multi] or 
[FlexiZone - Single ] in the normal view, precise focus may not be 
achieved.
Notes for AF
When in magnified view, Continuous AF (p.204) will not be executed.

Shooting Conditions that Make Focusing Difficult
Low-contrast subjects such as the bl ue sky, solid-color flat surfaces 
or when highlight or shadow details are lost.
 Subjects in low light.
 Stripes and other patterns where there is contrast only in the 
horizontal direction.
 Subjects with repetitive patterns (Example: Skyscraper windows, 
computer keyboards, etc.).
 Fine lines and subject outlines.
 Under a light source whose brightness, color, or pattern keeps 
changing.
 Night scenes or points of light.
 The image flickers under fl uorescent or LED lighting.
 Extremely small subjects.
 Subjects at the edge of the picture.
 Strongly backlit or reflective subjects (Example: Car with a highly 
reflective body, etc.).
 The AF point covers both near and distant subjects (Example: 
Animal in a cage, etc.).
 Subjects that keep moving within the AF point and cannot keep still 
due to camera shake or subject blur.
 A subject approaching or movi ng away from the camera.
 Autofocusing while the subject is very far out of focus.
 Soft focus effect is applied with a soft focus lens.
 A special effect filter is used.
 Noise (spots, banding, etc.) appears on the screen during AF.

Using AF to Focus (AF Method)
If focus is not achieved with the shooting conditions on the preceding 
page, set the lens focus mode switch to < MF> and focus manually.
 If you use AF with any of the following  lenses, focusing may take longer 
or correct focus may not be achieved. EF50mm f/1.4 USM, EF50mm f/1.8 II, EF50mm f/2.5 Compact Macro, 
EF75-300mm f/4-5.6 III, EF75-300mm f/4-5.6 III USM
For information on discontinued lenses, refer to the Canon Web site.
 If you shoot a peripheral subject and it is out of focus, aim the center AF 
point or zone over the subject to focus, focus again and then take the 
picture.
 The AF-assist beam will not be emit ted. However, if an EX-series 
Speedlite (sold separately) equipped with an LED light is used, the LED 
light will turn on for AF-assist when necessary.
 In magnified view, focusing may be diff icult due to camera shake. Using 
a tripod is recommended.

General Live View Shooting Cautions
Image QualityWhen you shoot at high ISO speeds,  noise (such as dots of light and 
banding) may become noticeable.
 Shooting in high temperatures may cause noise and irregular colors in 
the image.
 If Live View shooting is used continuously for a prolonged period, the 
camera’s internal temperature may rise, and image quality may 
deteriorate. Always exit Live View shooting when you are not shooting.
 If you shoot a long exposure while the  camera’s internal temperature is 
high, image quality may deteriorate. Exit Live View shooting and wait a 
few minutes before shooting again.
White < s> and Red < E> Internal Temperature Warning Icons If the camera’s internal temperature increases due to prolonged Live 
View shooting or under a high ambient temperature, a white < s> or red 
< E > icon will appear.
 The white < s> icon indicates that the image quality of still photos will 
deteriorate. It is recommended that you temporarily exit Live View 
shooting and allow the camera to cool down before shooting again.
 The red < E> icon indicates that the Live View shooting will soon stop 
automatically. If this happens, you will not be able to shoot again until the 
camera’s internal temperature decreases. Exit the Live View shooting or 
turn off the power and let the camera rest for a while.
 Using Live View shooting at a high temperature for a prolonged period 
will cause the < s> or < E> icon to appear earlier. When you are not 
shooting, always turn off the camera.
 If the camera’s internal temperature is high, the quality of images shot 
with high ISO speed or long exposure may deteriorate even before the 
white < s> icon is displayed.
Shooting Results If you take the picture in magnified view, the exposure may not come out 
as desired. Return to the normal view before taking the picture. In 
magnified view, the shutter speed and aperture will be displayed in 
orange. Even if you take the picture in magnified view, the image will be 
captured in the normal view range.
 If [z 2: Auto Lighting Optimizer ] (p.136) is set to any setting other 
than [ Disable ], the image may look bright even if a decreased exposure 
compensation or decreased flash exposure compensation is set.
 If you use a TS-E lens (except the TS-E17mm f/4L or TS-E24mm f/3.5L 
II) and shift or tilt the lens or use an Extension Tube, the standard 
exposure may not be obtained or an irregular exposure may result. 
						

							219
General Live View Shooting Cautions
Live View ImageUnder low- or bright-light conditions, the Live View image may not reflect 
the brightness of the captured image.
 Even if a low ISO speed is set, noise may be noticeable in the displayed 
Live View image under low light. However, when you shoot, the image 
recorded will have minimal noise. (The image quality of the Live View 
image is different from that of the recorded image.)
 If the light source (illumination) within the image changes, the screen 
may flicker. If this happens, exit Live View shooting and resume shooting 
under the actual light source.
 If you point the camera in a different direction, it may throw off the Live 
View image’s correct brightness momentarily. Wait until the brightness 
level stabilizes before shooting.
 If there is a very bright light source in the image, the bright area may 
appear black on the LCD monitor. However, the actual captured image 
will correctly show the bright area.
 In low light, if you set the [ 52: LCD brightness ] to a bright setting, noise 
or irregular colors may appear in the Live View image. However, the 
noise or irregular colors will not be recorded in the captured image.
 When you magnify the image, the image sharpness may look more 
pronounced than in the actual image.
 If the shutter speed is 1 sec. or slower, “ BUSY” is displayed on the LCD 
monitor, and the Live View display will not appear until the exposure is 
completed.
Custom Functions During Live View shooting, some Custom Function settings will not take 
effect (p.337).
Lens and FlashIf the attached lens has an Image Stabilizer and you set the Image 
Stabilizer (IS) switch to < 1>, the Image Stabilizer will operate at all 
times even if you do not press the shutter button halfway. The Image 
Stabilizer consumes battery power and may decrease the number of 
possible shots. If you use a tripod or if the Image Stabilizer is not 
necessary, it is recommended that you set the IS switch to < 2>.
 The focus preset function is possible for Live View shooting only when 
using a (super) telephoto lens equipped with the focus preset mode, 
available since the second half of 2011.
 FE lock will not work if the built-in flash is used. FE lock and modeling 
flash will not work if an exte rnal Speedlite is used.
