Changing the Focus Target
Manually (AF Assist)
When Focus >AF Assist (page 77) in the
Shooting menu is set to On, you can select the
target for auto focus during auto focus using
the focus ring on the lens.
Auto focus operation is restored when you
stop operating the focus ring.
Setting Focus >AF Subj. Shift Sens.
(page 77) in the Shooting menu to 1
(Locked On) is convenient when you want the
auto focus operation to continue as-is when
the focus position moves to a subject with a
different distance.
Using Manual Focus Temporarily
(Push Manual Focus)
Press the PUSH AUTO FOCUS button
(page 6) when in auto focus mode to
focus manually while the button is pressed.
The focus returns to auto focus when you
release the button.
This allows you to temporarily stop auto focus
and focus manually when something that is
not the subject of shooting crosses in front of
the subject.
[Tip]
The same operation is supported using an assignable
button (page 41) assigned with Push AF/Push MF.
