PRECAUTIONS WHEN USING THE LENS WITH A FLASH
Built-in Flash
The built-in flash can not be used when the distance is less than 0.7m. When the flash is
used within 0.7m, that causes incorrect exposure control and vignetting in the picture
corners.
• The built-in flash may be blocked by the lens hood. Always make sure to remove the
lens hood before using the built-in flash.
