switch the mode as required.
All scene modes use the program AE mode.

that can be selected are described below.
Exposure modes that can be selected
Mode
Program AE mode. The exposure time and camera gain are automatically set according to the brightness of the
PROG subject.
Suitable for subjects that are comparatively bright. (Initial setting)
Manual exposure mode. The user sets both the exposure time and camera gain manually.
MANU Suitable when capture is repeated under a specific exposure setting or for a specific purpose such as fluorescence
microscopy and observation under a stereoscopic or metallurgical microscope.
Focus-priority AE mode. The camera gain automatically increases to keep the exposure time short so that a dark
F.AE
subject can be focused more easily. Bright spots or banding noise may increase in this mode.
When the exposure mode is changed automatically
The exposure mode may be changed automatically in the following cases:
 When [SCENE/CSM] is selected
The image mode changes to the one specified in the selected scene mode or custom setting.
 When [CLR SET] is executed
The exposure mode is set to [PROG] when [CLR SET] is executed from the [CAMERA MENU: IMAGE] screen.
Limits of program AE mode
The table below shows the maximum camera gain and the lowest exposure time in program AE mode.
