Precautions When The Flash Is Used - Pentax smc -FA Operating Manual

PRECAUTIONS WHEN THE FLASH IS
USED
Built-in FLASH
With the built-in flash in popped-up position,
the flash can be used if no warning indication
appears when the shutter release button is
pressed halfway down. However, some lens-
es cause vignetting in the picture corners,
even though warning indication does not
appear. For more details, refer to page 38
and 39.
Remove the lens hood when the built-in
flash is used because the flash light will be
blocked by the lens hood.
