Setting Movie Servo AF
Cautions When [Movie Servo AF] is Set to [Enable]
o
Shooting Conditions that Make Focusing Dicult
• A fast-moving subject approaching or moving away from the camera.
• A subject moving at a close distance to the camera.
• When shooting with a higher f/number.
• Also see “Shooting Conditions that Make Focusing Dicult” on page
275.
o
Since the lens is driven continuously and the battery power is consumed,
the possible movie shooting time (p.612) will be shortened.
o
If AF operations are performed or you control the camera or lens during
movie recording, the camera’s built-in microphone may also record
mechanical sounds of the lens or sounds of camera/lens operations. In
this case, using an external microphone may reduce these sounds. If
the sounds are still distracting with an external microphone, it may be
more eective to remove the external microphone from the camera and
position it away from the camera and lens.
o
Movie Servo AF will pause during zooming or magnied view.
o
During movie shooting, if a subject approaches or moves away or if
the camera is moved vertically or horizontally (panning), the recorded
movie image may momentarily expand or contract (change in image
magnication).
o
Before setting the lens focus mode switch to <MF> during Movie Servo
AF, set the camera’s power switch to <
