Canon EOS 30D - Manual (Page 92)

This mode is for obtaining a wide depth of field automatically between a
near subject and far subject. It is effective for group photos and
landscapes. The camera uses the nine AF points to detect the nearest
and farthest subjects to be in focus.
* <8> stands for Auto-depth of field.

8 Automatic Depth-of-Field AE
The <8> mode cannot be used if the lens’ focus mode switch is set
to <MF>. The result will be the same as using the <d> mode.
If the “30"” shutter speed blinks, it indicates that the subject is too dark.
Increase the ISO speed.
If the “8000” shutter speed blinks, it indicates that the subject is too
bright. Decrease the ISO speed.
If the aperture blinks, it indicates that the exposure level is correct but the
desired depth of field cannot be obtained. Either use a wide-angle lens or
move further away from the subjects.
In this shooting mode, you cannot freely change the shutter speed and
aperture. If the camera sets a slow shutter speed, hold the camera
steady or use a tripod.
If you use flash, the result will be the same as using <d> with flash.
