Notes for Movie Shooting
Each time you shoot a movie, a new movie file is created on the card.

The movie image's field of view is approx. 100% (with movie recording

size set to [1920x1080]).
Stereo sound is recorded by the camera's built-in microphones.

If you connect the Directional Stereo Microphone DM-E1 (sold

separately) to the camera's external microphone IN terminal (p.28), the
external microphone is given the priority.
With a fully-charged Battery Pack LP-E17, the possible movie shooting

time will be as follows: approx. 1 hr. 55 min. at room temperature (23°C /
73°F) and approx. 1 hr. 50 min. at low temperatures (0°C / 32°F) (with
movie recording size set to L6/5X and [z4: Movie Servo
AF: Disable] set).
The focus preset function is possible for movie shooting when using a

(super) telephoto lens equipped with the focus preset mode, released in
and after the second half of 2011.
