Exposure
Warning Indications
✔ If the aperture value blinks, the desired depth of field cannot be obtained. Use a
wide-angle lens or move farther from the subject and repeat steps 4 through 6 on
the preceding pages.
✔ If the shutter speed of 30” and the maximum aperture of the lens blink, the scene
will be underexposed and Depth-of-Field AE cannot be carried out. Consider using
flash.
✔ If the shutter speed of 8000 and the minimum aperture of the lens blink, the scene
will be overexposed. Select a lower ISO or use a neutral density (ND) filter to
reduce the amount of light entering the lens.
Tips
✔ When using a zoom lens, do not zoom until you finish capturing the image.
✔ Changing the focusing point during Depth-of-Field AE operation cancels any
previously set data.
✔ Flash cannot be used effectively in Depth-of-Field AE mode. Use of flash will
provide the same result as using flash in Program AE mode.
✔ When using a lens equipped with a focus range selector (such as the EF300mm f/
2.8L USM), be sure to set it to the maximum range.
✔ With a slow shutter speed, use a tripod to prevent camera shake.
✔ To cancel Depth-of-Field AE in mid-operation, press the Focusing Point Selector
button, the Shooting Mode Selector button, the AF mode Selector button or the
Metering Mode Selector button.
✔ For greater depth of field, use a wide-angle lens.
✔ For shallow depth of field, place both points 1 and 2 on the same point. This
method is effective for blurring the foreground and background when shooting
portraits. Use a telephoto lens for best effect.
