:Automatic Depth-of-Field AE 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 7 AF points to detect the nearest and farthest subjects to be in focus. ∗ "A-DEP" stands for Auto-depth of field. 1 Turn the Command Dial to < >. 2 Focus the subject. • Move the AF point over the subject and press the shutter button halfway. • All the subjects covered by the AF points which flashed in red will be in focus. • If you press the depth-of-field preview button while the exposure reading is displayed in the viewfinder, you can see the depth of field. (→page 41) 3 Check the viewfinder display and take the picture. • In the example above, the focus will be sharp between the front person on the left and the rear person on the right. The < > mode cannot be used if the lens' focus mode switch is set to (or on older lenses). • If the aperture blinks, it indicates that the exposure level is correct but the desired depth of field cannot be achieved. 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 flash is used, the result will be the same as using flash in the < > mode. 43
