Pentax Lens manual Precautions When the Flash is Used, Built-in Flash

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.
