The AF-ON Buttons
An alternative means of activating autofocus is to press the AF-ON button (A) or,
when the shutter-release button for vertical shooting is unlocked, the AF-ON button
for ver tical shooting (B). Either operation has the same effect as pressing the shut-
ter-release button halfway.

performed using the AF-ON buttons to avoid accidental shutter release.
