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 AF-assist beam will not be em itted. However, if an EX-series 
Speedlite (sold separately) equipped  with a LED light is used, the LED 
light will turn on for  AF-assist when necessary  in the Live mode and u 
(face detection) Live mode.

Live View Shooting Cautions
White  and Red < E> Internal Temperature Warning Icons  If the camera’s internal temperatu re increases due to prolonged Live 
View shooting or a high ambi ent temperature, a white  icon will 
appear. If you continue sh ooting while this icon is displayed, the image 
quality of still photos may deteriora te. You should stop the Live View 
shooting and allow the  camera to cool down before shooting again.
  If the camera’s internal temperatu re 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 be terminated 
automatically. If this happens, you will  not be able to shoot again until the 
camera’s internal temperature decrea ses. Turn off the power and let the 
camera rest for a while.
  Shooting with the Live View func tion at a high temperature for a 
prolonged period will cause the < s> and < E> icons to appear earlier. 
When not shooting, tu rn off the camera.
Live View Image Cautions Under low- or bright-light conditio ns, the Live View image might not 
reflect the brightness  of the captured image.
  If the light source within the image  changes, the screen might flicker. If 
this happens, stop the Live View shooting  and resume shooting under 
the actual light so urce to be used.
  If you point the camera in  a different direction, it might 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 pictur e, such as the sun, the 
bright area might appear  black on the LCD monitor.  However, the actual 
captured image will correc tly show the bright area.
  In low light, if you set the [ 6 LCD brightness ] to a bright setting, 
chrominance noise may appear in th e Live View image. However, the 
chrominance noise will not be recorded in the captured image.
  When you magnify the image, the image sharpness may look more 
pronounced than it really is.

Live View Shooting Cautions
Shooting Result Cautions When you shoot continuous ly with the Live View function for a long 
period, the camera’s internal temp erature may increase and it can 
degrade image quality. Terminate Live  View shooting when not shooting 
images.
  Before taking a long exposure, stop  Live View shooting temporarily and 
wait several minutes before shoo ting. This is to prevent image 
degradation.
  Live View shooting in high temperatures and at high ISO speeds may 
cause noise or irregular colors.
  When you shoot at high ISO speeds,  noise (banding, dots of light, etc.) 
may become noticeable.
  If you take the picture during magn ified view, the exposure might not 
come out as desired. Return to the n ormal view before taking the picture. 
During the magnified vi ew, the shutter speed and aperture will be 
displayed in orange. Even  if you take the picture during magnified view, 
the image will be captured in the normal view.
  If [2  Auto Lighting Optimizer ] (p.107) is not set to [Disable], the 
image may look bright ev en if a decreased exposure compensation or 
decreased flash exposure co mpensation has been set.
  If you use a TS-E lens  to shift the lens vertically or use an Extension 
Tube, the standard exposure might not be obtained or an irregular 
exposure may result.
Custom Function Cautions  During Live View shooting, certain Cu stom Function settings will not take 
effect (p.217).
Lens and Flash Cautions  The focus preset featur e on super telephoto lenses cannot be used.
  FE lock is not possible when the built -in flash or an external Speedlite is 
used. Modeling flash will not wo rk with an external Speedlite.
