3 Menu Function Settings [z4] Menu When you select [Movies] under [z4: LV z/k set.], the [z4] [z5] tabs for movie shooting will appear. The menu options are as follows. AF mode The AF modes will be the same as described on pages 213-219. You can select [Live mode], [u Live mode], or [Quick mode]. Note that continuous focusing of a moving subject is not possible. Even if the AF mode is set to [Quick mode], it will switch to [Live mode] during movie shooting. Grid display With [3x3 l] or [6x4 m], you can display grid lines to help you level the camera vertically or horizontally. Also, with [3x3+diag n], the grid is displayed together with diagonal lines to help you align the intersections over the subject for better balance in the composition. Movie recording size You can set the movie recording size (image size, frame rate, and compression rate). For details, see pages 237 to 239. Sound recording You can set sound recording settings.
