Depth-of-field AE (DEP): You Set the Depth of Field
72
• When using a zoom lens, do not change the zoom focal length while using the
depth-of-field AE mode.
• After setting one or two dEP points, do not change the active focusing point.
Doing so will cancel the dEP point(s) that has been set and you will have to start
over with the newly selected focusing point.
• Depth-of-field AE cannot be used with flash. If flash is used, the result will be the
same as using Program AE with flash.
• If depth-of-field AE is used with a lens having a focusing limiting switch (like the
EF 300mm f/2.8 lens), set the switch to the maximum focusing distance range.
• If a slow shutter speed has been set, use a tripod to prevent camera shake.
• If six seconds elapse and the display turns off before you complete the procedure,
the DEP settings entered so far will be canceled. In such a case, you must start
over again.
• To cancel the depth-of-field AE mode midway, press the <
> button, <
>
button, or <
> button.
• To further increase the depth of field, use a wide-angle lens.
• Setting dEP points 1 and 2 at the same point on the subject will make the depth of
field shallow. The foreground and background will then be blurred, making the
subject stand out. Using a telephoto lens enhances this effect.
• If the aperture blinks, the desired depth of field cannot be obtained. (However, you can
still take the picture and obtain a proper exposure.) Use a wide-angle lens or move away
from the subject and repeat steps 4 to 6.
• If the 30” shutter speed and the lens’
maximum aperture (smallest CF-
number) blink, the scene is too dark
and the picture cannot be taken in the
depth-of-field AE mode.
• If the 8000 shutter speed and the lens’
minimum aperture (largest f-number)
blink, the scene is too bright. Use a
neutral density (ND) filter to reduce the
amount of light entering the camera.
