the camera will focus the face 
covered by the < p> frame.
X When focus is achi eved, the AF point 
will turn green a nd the beeper will 
sound.
X If focus is not achieved, the AF point 
will turn orange.
  If a face cannot be detected, the AF 
point < > will be displayed and AF 
will be executed at the center.
3Take the picture.
 Check the focus and exposure, then 
press the shutter button completely to 
take the picture (p.201).
 If the focus is far off, face detect ion will not be possible. If the lens 
enables manual focusing even while the lens focus mode switch is set to 
, turn the focusing ring to attain  rough focus. The face will then be 
detected and < p> will be displayed.
  An object other than a human fa ce may be detected as a face.
 
Face detection will not work  if the face is very small or large in the picture, 
too bright or too dark, titled horizont ally or diagonally, or partially hidden.
 The < p> focusing frame may cover  only part of the face.
 When you press  straight down or press < 0>, the AF mode will 
switch to the Live mode  (p.209). You can tilt  to move the AF point. 
Press < 9> straight down again or press < 0> to return to the  u (face 
detection) Live mode.
  Since AF is not possible  with a face detected near the edge of the 
picture, the < p> will be grayed out. Then if you press  the shutter button 
halfway, the center AF poin t < > will be used to focus.

AF operation
 Focusing will take slightly longer.
  Even when focus has been achieved, pressing the shutter button 
halfway will focus again.
  The image brightness may cha nge during and after the AF 
operation.
  If the light source changes while th e Live View image is displayed, 
the screen may flicker and focusing  may be difficult. If this happens, 
exit Live View shooting and autofocus  under the actual light source.
  If you press the < u> button in the Live mode, the image will be 
magnified at the AF point. If focusing  is difficult in the magnified view, 
return to the normal view and autofocus. Note that the AF speed 
may differ between the normal and magnified views.
  If you autofocus in the Live mode’s normal view and then magnify 
the image, the focus may no longer be correct.
  In the  u Live mode, pressing the < u> button will not magnify the 
image.
Live Mode and u (Face Detection) Live Mode Notes
  In the Live mode or  u (face detection) Live mode, if you shoot a 
peripheral subject and it is slightly  out of focus, aim the center AF point 
over the subject to focus,  then take the picture.
  The external Speedlite will not emit  the AF-assist beam. However, if an 
EX-series Speedlite (sold separately)  equipped with a LED light is used, 
the LED light will turn on automatica lly for AF-assist when necessary in 
the Live mode and  u (face detection) Live mode.

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 contin uously for a long period, the camera’s 
internal temperature may  rise, degrading image qua lity. Stop Live View 
shooting when not shooting images.
  If you shoot a long expo sure while the camera’s internal temperature is 
high, image quality may be  degraded. Stop Live View shooting and wait 
a few minutes before shooting again.
White < s> and Red  Internal Temperature Warning If the camera’s internal temperatu re increases due to prolonged Live 
View shooting or a high ambient  temperature, a white icon  will 
appear. If you continue sh ooting while this icon is displayed, the image 
quality may be degraded.  It is recommended to temporarily exit Live 
View shooting and allow the camera to  cool down before shooting again.
 
If the camera’s internal temperature  further increases while the white icon 
 is displayed, a red icon  will start blinking. This blinking icon is a 
warning that the Live View shooting will soon end automatically. If this 
happens, you will not be able to shoot again until the camera’s internal 
temperature decreases. 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> and < E> icons to appear earlier. When you are not 
shooting, turn off the camera.
  If the camera’s internal  temperature is high, the image quality of high ISO 
speed images or long  exposures may be degraded even before the 
white icon  is displayed.
Shooting Result If you take the picture in  magnified view, the exposu re may not come out as 
desired. Return to the normal view befor e 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.
 If [z 2: Auto Lighting Optimizer ] (p.146) is not set to [Disable], the 
image may look bright ev en if a decreased exposure compensation or 
decreased flash exposure  compensation was set.
 
If you use a TS-E lens to shift the lens vertically or use an Extension Tube, the 
standard exposure may not  be obtained or an irregular exposure may result.

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.
  If the light source within the image ch anges, the screen may flicker. If this 
happens, exit Live View shooting and resume shooting under the actual 
light source to be used.
  If you point the camera in  a different direction, it may throw off the Live 
View image’s correct brightness mo mentarily. Wait until the brightness 
level stabilizes be fore shooting.
  If there is a very bright  light source in the pict ure, the bright area may 
appear black on the LCD monitor. Ho wever, 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 it really is.
Custom Functions During Live View shooting, certain Cu stom Function settings will not take 
effect (p.318).
Lens and Flash  The focus preset function  is possible during Live View shooting only 
when using a (super) te lephoto lens equipped with the focus preset 
mode marketed since the second half of 2011.
  FE lock and mode ling flash will not work if an  external Speedlite is used.

Shooting Movies
The live image displayed on the camera’s LCD monitor 
can be recorded as a movi e to the card. The movie 
recording format will be MOV.
Cards that Can Record Movies  When shooting movies, use a la rge-capacity card with a 
fast writing/reading spee d as shown in the table.
  If you use a slow-writing card wh en shooting movies, the movie 
may not be recorded pr operly. Also, if you play back a movie on 
a card with a slow reading spee d, the movie may not play back 
properly.
  If you want to  shoot still photos while  shooting a movie, you will 
need an even faster card.
  To check the card’s reading/writing speed, refer to the card 
manufacturer’s Web site.
