Hints & Tips
With "AI Servo AF" mode, it is possible to start
shooting using a manually selected AF frame
covering the subject. This makes continue tracking
of the subject easy. For convenience it is possible to
select the same start position for Single Point AF
and 61 Point automatic selection AF and switch
between the two as required.
