3 Menu Function Settings AF with shutter button during movie recording When you press the shutter button while shooting a movie, you can shoot a still photo. The default setting is [ONE SHOT]. • When [ONE SHOT] is set: • You can refocus and shoot a still photo by pressing the shutter button halfway while shooting a movie. • When shooting a static subject (not moving), 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 focus. Grid display With [Grid 1l] or [Grid 2m], you can display grid lines. You can check horizontal or vertical tilt when shooting. Metering timer N You can change how long the exposure setting is displayed (AE lock time). Movie recording size You can set the movie recording size (image size and frame rate). For details, see pages 193-194. 209
