C.Fn II -2 Acceleration/deceleration tracking
This sets the tracking sensitivity for moving
subjects whose speed can suddenly change
dramatically by starting or stopping suddenly, etc.
0:
Suited for subjects that move at a fixed speed.
+2 / +1:
Effective for subjects having sudden movements, sudden acceleration/
deceleration, or sudden stops. Even if the moving subject’s speed suddenly
changes dramatically, the camera continues to focus the target subject. For
example, for an approaching subject, the camera becomes less prone to
focus behind it to avoid subject blur. For a subject stopping suddenly, the
camera becomes less prone to focus in front of it. S2 can track
dramatic changes in the moving subject’s speed better than with +1.
However, since the camera will be sensitive to even slight movements of the
subject, the focusing may be unstable momentarily.
C.Fn II -3 AI Servo 1st image priority
You can set the AF operation characteristics and
shutter-release timing for the first shot during
continuous shooting with AI Servo AF.
Equal priority:
Equal priority is given to focusing and shutter release.
: Release priority
Pressing the shutter button takes the picture immediately even if focus has
not been achieved. It is effective when you want give priority to the shutter
chance rather than to focus.
: Focus priority
Pressing the shutter button does not take the picture until focus has been
achieved. Effective when you want to achieve focus before capturing the shot.
