f: Changing the Depth of Field

108

To obtain a correct flash exposure, the flash output will be set

automatically to match the set aperture (autoflash exposure). The

shutter speed will be set automatically between 1/200 sec. - 30 sec. to

suit the scene’s brightness.

In low light, the main subject is exposed with the auto flash metering,

and the background is exposed with a slow shutter speed set

automatically. Both the subject and background look properly exposed

(automatic slow-speed flash sync). If you are handholding the camera,

keep it steady to prevent camera shake. Using a tripod is recommended.

To prevent a slow shutter speed, under [53: Custom Functions

(C.Fn)], set [3: Flash sync. speed in Av mode] to [1: 1/200-1/60 sec.

auto] or [2: 1/200 sec. (fixed)] (p.259).

The aperture opening (diaphragm) changes only at the moment when

the picture is taken. Otherwise, the aperture remains fully open.

Therefore, when you look at the scene through the viewfinder or on the

LCD monitor, the depth of field will look narrow. With the procedure

below, you can check the depth of field before taking the picture.
