4.7 Front/rear dial lock mechanisms
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.
Press 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 same buttons until “OF” blinks.
3. “L” is displayed on the main LCD to indicate that operation of the
front and rear dials is blocked.
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.
