When the shutter speed is set to 2 sec.

!SLOW

While using slow synchronization with flash shooting, you can also use this function to 
achieve red-eye reduction. When shooting a subject against a night scene, this function 
allows you to reduce the red-eye phenomenon. As the time from emitting pre-flashes to 
shooting is long in 2nd curtain synchronization, it is difficult to achieve red-eye reduction. 
Hence, only 1st curtain synchronization setting is available.

The flash fires regardless of the light conditions. 
This mode is useful for eliminating shadows on 
the subject’s face (such as shadows from tree 
leaves), in a backlight situation, or for correcting 
the color shift produced by artificial lighting 
(especially fluorescent light).

• When the flash fires, the shutter speed is set to 1/180 sec. or less. When shooting a subject 

against a bright background with the fill-in flash, the background may be overexposed. In this 
case, use the optional FL-50R external flash or a similar flash and shoot in the Super FP flash 
mode.

The flash does not fire.
Even in this mode, the flash can be used as an AF illuminator when it is raised.

This allows the built-in flash to output a fixed amount of light. To shoot with manual flash, set 
the f-number on the lens based on the distance to the subject.
