PRECAUTIONS WHEN USING THE LENS WITH A FLASH 21
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, it causes incorrect exposure control and vignetting in the picture corners.
• Refer to the “Compatibility of DA Lenses with the Built-in Flash” chart on page 23 for
information on the compatibility of the built-in flash with the lens being used. Furthermore,
please note that when using the
-series camera, a warning indication does not
appear even when taking a picture with a built-in flash that is incompatible with the lens
being used.
• If the built-in flash is used with the lens hood attached to the lens, the flash light will be
blocked by the lens hood. Always make sure to remove the lens hood before using the
built-in flash.
External Flash
The external flash can be used while the lens hood is attached. However, the following
conditions apply for some types of lens.
● DA 14mm f/2.8ED (IF)
The AF540FGZ and AF360FGZ external flash units can only be used when the wide-angle
panel is used (it is also possible to use the lens hood). Other external flash units are not
recommended because their coverage angle is not compatible with the angel of view of the lens.
● DA FISH-EYE 10-17 mm f/3.5-4.5ED (IF)
External flash units cannot be used because their coverage angle is not compatible.
