Precautions When The Flash Is Used - Pentax INTERCHANGEABLE LENS 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.
• When using the * ist D camera, no warning
indication appear in the viewfinder even if
you use the incompatible lenses with the
built-in flash.
Refer to the lens compatibility with the
built-in flash on the * ist D operating manu-
al.
• Remove the lens hood when the built-in
flash is used because the flash light will be
blocked by the lens hood.

LENS AND LENS HOOD WITH THE EXTERNAL FLASH.
The vignetting will not occur without the lens
hood.
