Flash shooting
When the shutter speed is set to 2 sec.
Slow synchronization (1st curtain)/Red-eye reduction flash !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.
Fill-in flash #
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).

Notes
• 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.

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

Manual flash
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.
