40 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.
