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, 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 42 for
information on the compatibility of the built-in flash with the lens being used.
External Flash
The external flash can be used while the lens hood is attached. However, the following
conditions apply to some types of lens.
zDA 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 angle of view of the
lens.
zDA 21mm f/3.2 AL Limited
External flash units can be used while the lens hood is mounted without problems if it is
possible to set their zoom [coverage angle] up to 28mm.
zDA FISH-EYE 10-17mm f/3.5-4.5ED [IF]
External flash units cannot be used because their coverage angle is not compatible with the
angle of view of the lens.
