3 Menu Function Settings  AF with shutter button during movie recording While shooting a movie, you can also take a still photo by pressing the shutter button completely. By default, AF operation is set to [One-Shot AF]. When [One-Shot AF] is set: • You can refocus and shoot a still photo by pressing the shutter button halfway while shooting a movie. • When shooting a still subject, you can perform shooting in precise focus. When [Disable] is set: • You can immediately start shooting a still photo by pressing the shutter button, even though focus is not achieved. This is effective when you want to give priority to the shooting opportunity rather than to focusing.  Grid display With [Grid 1l] or [Grid 2m], you can display grid lines. You can check horizontal or vertical tilt when shooting.  Metering timerK You can change how long the exposure setting is displayed (AE lock time). Z2  Movie recording size You can set the movie recording size (image size, frame rate, and compression method). For details, see pages 233-235. 250
