The Built-in Flash
Use with lenses with focal lengths of 24–300 mm in FX format (0 375).
Remove lens hoods to prevent shadows. The flash has a minimum
range of 0.6 m (2 ft) and can not be used in the macro range of macro
zoom lenses.
i-TTL flash control is available at ISO sensitivities between 100 and 6400;
at other sensitivities, the desired results may not be achieved at some
ranges or aperture values.
If the flash fires in continuous release mode (0 103), only one
photograph will be taken each time the shutter-release button is
pressed.
The shutter release may be briefly disabled to protect the flash after it
has been used for several consecutive shots. The flash can be used
again after a short pause.
