constant speed is common
A tra ck and fi eld e x ampl e w here an
athlete is running directly towards the

shots of subjects in this situation.
[Accel./decel. tracking] is a tracking setting for
subjects that experience significant changes in
speed, move or stop suddenly. The default
setting is [0], which is suited for shooting
subjects that move at steady speeds, .
[+1/+2] is suited to shooting subjects that stop/
change direction suddenly or accelerate/
decelerate suddenly, enabling it to continue to
focus on the subject. +2 can handle greater

Other parameters are the same, so first try
shooting with default settings, then increase
the setting to [+1] and then [+2] settings when
more effective settings are desired.
Examples where the [+]

Sports where athletes movement
sudden stop or start

as they land, a normal setting may not be
able to capture it, however, it is possible
to continue focusing on the athlete with
[Accelerate / decelerate Tracking] set to
[+1].
