Autofocus Tips

Focusing with the AF-ON Button

If AF-ON only is selected for Custom Set-
ting a4 (AF activation), the B button
can be used to focus and the shutter-re-
lease button to release the shutter. To
lock focus or suspend autofocus when
an obstacle comes between you and
the subject, release the B button.
In the AF-ON position, the focus opera-
tion selection switch on some telephoto
lenses functions in the same way as the
B button.

Choosing the Number of Focus Points

Custom Setting a7 (Number of focus points) can be used
to choose the focus points available for manual focus point
selection. Choose 11 points for faster focus point selection
when composing photographs.
