Taking Photographs—Focus

a1—AF- C Mode Priority (

185)

If Focus is selected for Custom Setting a1 (AF-C mode priority), photographs can be
taken in continuous servo-AF only when the camera is in focus. Select FPS rate + AF
for improved focus during continuous shooting.

a2—AF-S Mode Priority (

185)

If Release is selected for Custom Setting a2 (AF-S mode priority), photographs can
be taken in single servo-AF even when the camera is not in focus.

a5—AF Activation (

188)

If AF-ON only is selected for Custom Setting a5 (AF activation), the camera will only
focus when one of the AF-ON buttons is pressed, not when the shutter-release button
is pressed halfway.

a8—Vertical AF- ON (

190)

Custom Setting a8 (Vertical AF-ON) controls whether the AF-ON button for vertical
shooting is used to initiate autofocus, select the focus area, or both.

c2—AE-L / AF-L (

If desired, the AE-L / AF-L button can perform the same function as the AF-ON button.

The AF- ON Buttons

For the purpose of focusing the camera, pressing either of the AF-ON buttons has the
same effect as pressing the shutter-release button halfway (the AF-ON button for verti-
cal shooting can only be used when the shutter-release button for vertical shooting is
unlocked).
