When the Electronic Dial Lock is “On,” all currently set values in “Av” (Aperture Priority
AE), “Tv” (Shutter Priority AE) and “M” (Manual mode) cannot be adjusted with the
front or rear dials. This prevents accidental change of shutter speed or aperture
values.
1. Set the shutter release mode selector lever
to “S” or “C” (to turn the power on).
2. Hold down both the multiple exposure mode
button and the auto bracketing mode button
for approximately one second, until the "On"
indicator blinks.
To release the mode, hold down the buttons
until "OF" blinks.
3. When this mechanism is selected, the “L” is
displayed on the LCD.
Front / Rear Dial Lock Mechanisms
When the dial lock is ON, the shutter speed and aperture will not change even if you
turn the front or rear dial.
When you activate the electronic dial lock, and if you then operate the electronic dial,
the dial lock indicator “L” on the main panel blinks for three seconds to show that
the electronic dial lock is functioning.
The setting will be stored after one second.
Depth of Field
Depth of field (D.O.F.) is defined as the zone of sharpness before and behind the
plane of focus. It depends on distance to subject, focal length of lens, aperture setting
and distance the lens is focused at.
In addition to visual observation via the depth of field preview button (See page 66.),
the D.O.F. can be determined by using the depth of field scale on each lens. The f/
stop numbers appear on both the right and left side of the white index mark in the
center of the scale. Simply read the figures which appear above the f/stop numbers on
the distance scale of the lens. (see illustration below)

Depth of Field Preview Button
When the preview button is pressed in, the depth of field for the aperture set on the
camera can be checked by looking through the viewfinder.
