k Preparing to Shoot Movies
With EF Cinema single focal length lenses, you can shoot at all movie-
recording quality settings. If you use an EF Cinema zoom lens, you can
shoot movies only with I Super 35mm Crop. (Since the image circle
is small, the image periphery will be dark if you shoot a movie in H A
B C quality or still photo.)
Use a large-capacity card with a fast writing/reading speed (required
card performance) as shown in the table. First, shoot a few test movies
to see if movies can be recorded accurately with a movie-recording size
you set (p.34).

If you use a slow-writing card when shooting movies, the movie may not
be recorded properly. Also, if you play back a movie on a card with a
slow reading speed, the movie may not play back properly.
If you want to shoot still photos while shooting a movie, you will need an
even faster card.
To check the card’s writing/reading speed, refer to the card
manufacturer’s Web site.
To optimize the card’s performance, format the card before shooting
movies. For card-formatting cautions, see zpage 55.
