Taking Photographs—Flash Photography
Using the Built-in Speedlight
If the built-in Speedlight is used in continuous shooting mode, only one photograph
will be taken each time the shutter-release button is pressed.
Vibration reduction (available with VR lenses) does not take effect if the shutter-release
button is pressed halfway while the built-in Speedlight is recharging.
After the built-in Speedlight has been used for several consecutive shots, it may turn
off briefl y to protect the fl ash. The built-in Speedlight can be used again after a short
pause.
Flash Range, Aperture, and Sensitivity
Flash range varies with sensitivity (ISO equivalency) and aperture.

The minimum distance at which the built-in Speedlight can be used is 0.6 m (2´).
In P,
, , , and modes, the maximum aperture (minimum f/-number) is limited
according to sensitivity (ISO equivalency) as shown below:

For each one-step increase in sensitivity (e.g., from 200 to 400), aperture is stopped
down by half an f/-stop. If the maximum aperture of the lens is smaller than that listed
above, the maximum value for aperture is the maximum aperture of the lens.
i-TTL fl ash control is available at all sensitivity (ISO equivalency) settings.
