Red-eye reduction flash function
The red-eye reduction flash function with an external flash
attached can also be used depending on what type of an
external flash is attached, and it may have any restrictions for
usage. See page 70 for more details. The red-eye reduction flash
function can be used only when the external flash is set to the
TTL Auto Mode.
Trailing-Shutter-Curtain Flash function
When using the built-in flash and the external flash
simultaneously, the trailing-shutter-curtain-flash function for the
built-in flash also operates when the external flash is set to the
trailing-shutter-curtain flash function. Before shooting, confirm
that both flash units are fully charged.
Multi-burst flash with the Pentax dedicated flash

Type C or Type D with Type E. Refer to the overview of Flash
Function on page 70. The built-in flash can be operated with any
