AF operation
 It will take a slightly longer time to focus.
  Even when focus has been achieved, pressing the < p> button 
will focus again.
 
The image brightness may change during and after the AF operation. If the image flickers, making it difficult to focus, stop and resume the Live 
View shooting under the actual light source to be used. Check that the 
flickering has stopped, then autofocus.
  If you press the < u> button in the Live mode, the AF point area will 
be magnified. If it is difficult to focus 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 might be off.
  In the Live u mode, pressing the < u> button will not magnify the 
image.
Live Mode and Liveu (Face Detection) Mode Notes
  The face-detecting AF point might cover only part of the face.
  An object other than a human face might 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  horizontally or diagonally, or partially 
hidden.
 When you press  straight down, it will switch to the Live mode (p.123). 
You can tilt the 9 to switch to another AF point. If you press 9 
straight down again, it will switch back to Liveu (face detection) mode.  Since AF is not possible with a face detected near the edge of the 
picture, the < p> will be grayed out. Then when you press the < p> 
button, the center AF point < > will be used to focus.
  The AF-assist beam will not be emitted.
  Autofocus will not work with the rele ase button on the Remote Switch 
RS-80N3 and Timer Remote Controller TC-80N3 (both sold separately).

Shooting conditions which can make focusing difficult:
 Low-contrast subjects such as the  blue sky and solid-color surfaces.
  Subjects in low light.
  Stripes and other patterns where there is contrast only in the 
horizontal direction.
  Under a light source whose brightness, color, or pattern keeps 
changing.
  Night scenes or points of light.
  Under fluorescent lighting or when the image flickers.
  Extremely small subjects.
  Subjects strongly reflecting light.
  The AF point covers both a near and faraway subject (such as an 
animal in a cage).
  Subjects which 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 way out of focus.
  Soft focus effect is applied with a soft focus lens.
  A special effects filter is used.

Instructions for setting the [6 Live View 
function settings ] menu’s [Silent shoot. ] 
are explained below.
  Mode 1
The shooting operation noise is qui eter than the normal shooting. 
Continuous shooting is also  possible. High-speed continuous 
shooting will be approx. 5.8 fps.
  Mode 2
When you press the shutter button completely, only one shot will be 
taken. While you keep holding down the shutter button, the camera 
operation will be suspended. Then when you return to the shutter 
button’s halfway position, the camera operation will resume and the 
shooting sound will occur only then . By delaying the shooting sound, 
the disturbance can be minimized.  Even if continuous shooting is 
set, only a single shot can be taken in this mode.
  Disable
If you use a TS-E lens to make  vertical shift movements or use an 
Extension Tube, be sure to set this to [ Disable]. Setting it to [Mode 
1] or [ Mode 2 ] will result in incorrect or irregular exposures.
When you press the shutter button co mpletely, the shutter will sound 
like it took two shots. However, only one shot will be taken.
Silent ShootingN
  If you use flash, the [ Disable] operation will take effect even if you had 
set it to [ Mode 1] or [Mode 2 ].
  When using a non-Canon flash unit, set it to [ Disable]. (The flash will not 
fire if [Mode 1 ] or [Mode 2 ] is set.)

Notes about the Live View image Under low light or bright light conditions, 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 and resume the Live  View shooting under the actual 
light source to be used.
  If you point the camera in a different direction, it might 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 picture, such as the sun, the 
bright area might appear black on the LCD monitor. However, the actual 
captured image will correctly show the bright area.
  In low light, if you set the [ 6 LCD brightness ] to a bright setting, 
chrominance noise may appear in the 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.
Notes about the shooting results When you use Live View shooting for a long period, the camera’s internal 
temperature may increase and it can degrade image quality. Terminate 
Live View shooting when not shoot ing images. Before taking a long 
exposure, stop Live View shooting temporarily and wait several minutes 
before shooting.
  High temperatures, high ISO speeds,  or long exposures may cause 
noise or irregular colors in the image captured with Live View shooting.
  If you take the picture while the image is magnified, the exposure might 
not come out as desired. Return to the normal view before taking the 
picture. During the magnified view, the shutter speed and aperture will be 
displayed in red.
  Even if you take the picture during magnified view, the captured image 
will show the normal view.

Notes about Custom Functions Live View shooting will disable some  Custom Function settings (p.173).
  If [8 C.Fn II -4: Auto Lighting Optimizer ] (p.177) is not set to [3: 
Disable ], the image will look bright even if a decreased exposure 
compensation has been set.
Notes about lenses and flash  The focus preset feature on super  telephoto lenses cannot be used.
  FE lock is not possible when the built-in flash or external Speedlite is 
used. Modeling flash is not possible when external Speedlite is used.
