Depth-of-field AE

Exposure Warnings

•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 2 to 4.

•If both the shutter speed and aperture blink, you can still take the picture, but the picture will be too dark or too bright. For details, see the “Exposure Warnings” table (→p.157).

•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 select a different AF point. Otherwise, the dEP point(s) that you already set will be canceled and you will have to start over with the newly selected AF point.

•Using flash with the depth-of-field AE mode will obtain the same result 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/2.8L IS USM lens), set the switch to the maximum focusing distance range.

•With automatic AF point selection in the depth-of-field AE mode, only the center

AF point will be used for focusing.

•If a slow shutter speed has been set, use a tripod to prevent camera shake.

•If () elapse before you complete the DEP procedure, the dEP point(s) set 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.
