A3: Focus Tracking With Lock-On; A4: Focus Points Used - Nikon Z9 Settings Manual

a3: Focus Tracking with Lock‑On a3: Focus Tracking with Lock‑On
This menu contains two options: [Blocked shot AF response] and [Subject
motion].
Blocked Shot AF Response
■
If AF‑C is selected for focus mode, focus tracking with lock-on will prevent the camera refocusing
when your subject is briefly obscured by another object, ensuring that it will continue to track the
main subject once the obstacle has moved away. Choose the length of time before the camera
refocuses from [1 (Quick)], [2], [3], [4], and [5 (Delayed)]. Lock-on applies only while the camera is
focusing; to focus at a new distance without waiting for lock-on to end, re-initiate autofocus.
The camera will track and focus on objects at the same distance as the
main subject. High values (slow response) make the camera slow to re-
focus on obstacles when the shot is blocked. Select low values (quick
response) to quickly refocus on subjects passing in front of the camera
and for improved response when switching rapidly from one subject to
another.
Subject Motion
■
Choose how the camera tracks subjects in motion. Choose [Steady] for subjects approaching the
camera at a steady pace, like sprinters or race cars on a track, [Erratic] for long or triple jumpers and
other subjects prone to sudden stops and starts.
