1Select [Distortion correction].
2Select [Enable].
 Check that [ Correction data 
available ] is displayed for the 
attached lens.
  Select [ Enable], then press < 0>.
3Take the picture.
  The image will be recorded with the 
distortion corrected.
Distortion Correction
  When distortion correction is enabled, the camera records an image 
range narrower than the one seen through the viewfinder. (The image 
periphery is slightly trimmed...

3 Correction of Lens Aberrations due to Optical Characteristics N
The lens correction data for lens aberration corrections is registered 
(stored) in the camera. With [ Enable] selected, the peripheral 
illumination correction, distortion  correction, Digital Lens Optimizer, 
chromatic aberration correction, and  diffraction correction will be 
applied automatically.
With EOS Utility (EOS software,  p.598), you can check which lenses 
have their correction data registered in the camera. You can also...

Cautions for Lens Correction
 Peripheral illumination correction, distortion correction, chromatic 
aberration correction, and diffraction correction cannot be applied to 
JPEG images already taken.
  When using a non-Canon lens, setting the corrections to [ Disable] is 
recommended even if [ Correction data available ] is displayed.
  If you use magnified view during Live View shooting, the peripheral 
illumination correction and...

If you shoot an image with a fast shutter speed under a light source 
such as fluorescent light, the blinking of the light source causes flicker 
and the image may be vertically  unevenly exposed. If continuous 
shooting is used under these condi tions, uneven exposures or colors 
across the images may result. W hen you use this feature during 
viewfinder shooting, the camera detects the flickering frequency of the 
light source and takes the picture when the flicker causes less effect on 
exposure...

3 Reducing Flicker N
216
 If the subject is against a dark background or if there is a bright light in 
the image, flicker may not be properly detected.
  Under certain special types of lighting, the camera may not be able to 
reduce the effects of the flicker even when < G> is displayed.
  Depending on the light source, flicker may not be detected properly.
  If you recompose a shot, < G> may appear and disappear 
intermittently.
  Depending on the light sources or shooting conditions, the expected...

The range of reproducible colors is called “color space”. With this 
camera, you can set the color space for captured images to sRGB or 
Adobe RGB. For normal shooting, sRGB is recommended.
In the < A> mode, the color space is set automatically to [ sRGB].
1Select [Color space].
 Under the [ z2] tab, select [ Color 
space ], then press < 0>.
2Set the desired color space.
  Select [ sRGB] or [Adobe RGB ], then 
press < 0>.
This color space is mainly used for commercial printing and other 
industrial...

You can freely create and select the folder where the captured images 
are to be saved.
This operation is optional since a folder will be created automatically for 
saving captured images.
1Select [Record func+card/folder 
sel.].
 Under the [ 51] tab, select [ Record 
func+card/folder sel. ], then press 
< 0 >.
2Select [Folder].
