a3: Focus Tracking with Lock‑On
l
This menu contains two options:
Blocked shot AF response and Sub-
ject motion.
Blocked Shot AF Response
In continuous-servo AF, focus tracking with lock-on pre-
vents 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 refo-
cuses from 1 (Quick), 2, 3, 4, and 5 (Delayed). Lock-on ap-
plies 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 ob-
jects at the same distance as the main
subject. High values (slow response)
make the camera slow to refocus on ob-
stacles 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 sub-
ject to another.
