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 1 _] or [Grid 2_], you can display grid lines. You can
check horizontal or vertical tilt when shooting.
Metering timer _
You can change how long the exposure setting is displayed (AE lock
time).
