to appropriate for shooting result.
"Accelerate / decelerate Tracking" and "AF point auto switching" are absolutely some part of Camera's automatic
functions. Therefore it is not always possible that these automatic functions reflect 100% of your intended idea. If
you feel uncomfortable with shooting result, try to change the effect level of their functions.

The [AF pt auto switching] parameter is used
for setting characteristics of AF point switching
when the subject has a lot of movements. This
parameter is only for switching between
multiple AF points, so it is unavailable when
using AF area selection modes [Single-point
Spot AF] and [Single-point AF]. The [0] setting is
a standard setting for moderate switching of AF
points. The [+1/+2] settings are used when
shooting subjects with erratic movement which

manually selected AF point (AF point being
