If you cannot achieve focus under the shooting conditions listed on the 
preceding page, set the lens  focus mode switch to  and focus 
manually.
  If you shoot a peripheral subject and it is slightly 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 em itted. 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.
  During magnified view, camera shak e may make it harder to achieve 
focus. Using a trip od is recommended.

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 cont inuously 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 expo sure while the camera’s internal temperature is 
high, image quality may det eriorate. 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 temperatu re increases due to prolonged Live 
View shooting or under a high  ambient temperature, a white < s> or red 
 icon will appear.
  The white < s> icon indicates that the image  quality of still photos will 
deteriorate. You should exit Live Vi ew shooting and allow the camera’s 
internal temperature to co ol 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 decrease s. 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  or  icon to appear earlie r. 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 ex posures may deteriorate even before the white 
 icon is displayed.
Shooting Result
  If you take the picture in magnified view, the exposure may not come out 
as desired. Return to th e 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 3: Auto Lighting Optimizer ] (p.140) is set to other than [Disable ], 
the image may look bright even if  a decreased exposure compensation 
or decreased flash exposure compensation is set.

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. (T he image quality of the Live View 
image is different from t hat of the recorded image.)
  If the light source (illumination) wi thin 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 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 in the actual image.
Custom Functions
  During Live View shooting, some Cust om Function settings will not take 
effect (p.363).
Lens and Flash
  The focus preset function  is possible for Live View shooting only when 
using a (super) telephoto lens equi pped 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 ex ternal Speedlite is used.
