USING BUILT-IN FLASH
When subject brightness is insufficient, the flash-
recommended light (green
j
) lights up inside the viewfinder
when you lightly press shutter release button to activate the
exposure meter.
You can use the built-in flash anytime, regardless of ambient
lighting. For example, if your subject is backlit, you can use
the built-in flash to illuminate your subject and fill in shadows.
Important!
• Do not touch the flash when it is firing; normal
operation can cause it to heat up.
• Never fire the flash more than 20 consecutive times at
intervals of 5 sec. or shorter. This may impair flash
performance. If you fire the flash 20 consecutive times
at intervals of 5 sec. or shorter, let the flash rest at least
10 minutes before firing again.
When you continuously fire the flash, the camera's
handgrip may become hot; this is normal. Continuous
firing will result in a longer interval before the ready-light
lights up because it takes longer for the flash to
recharge automatically.
• When the built-in flash is activated, an accessory
Speedlight will not fire. When using a Speedlight, keep
the built-in flash in the locked down position.
• For usable lenses with built-in flash, see page 104.
AUTOMATIC BALANCED FILL-FLASH WITH
TTL MULTI SENSOR––3D MULTI-SENSOR
BALANCED FILL-FLASH AND MULTI-SENSOR
BALANCED FILL-FLASH
Combined with a D-type Nikkor lens, in automatic exposure
mode, the F70/F70D's built-in flash performs 3D Multi-Sensor
Balanced Fill-Flash. In 3D Multi-Sensor Balanced Fill-Flash
operation, just after you depress shutter release button and
before the shutter is activated, the built-in flash will fire a series
of weak pre-flashes (Monitor Pre-flashes) that are detected by
the camera's TTL Multi Sensor, then analyzed for brightness
and contrast. Additionally, Distance Information from the D-type
Nikkor lens in use, along with other exposure control
information, is integrated, thus automatically compensating
flash output level so that flash output and ambient light are
balanced. The Monitor Pre-flashes enable 3D Multi-Sensor
Balanced Fill-Flash to ensure correct exposure even in difficult
situations, including scenes with a very reflective object such as
a mirror or a white wall, and scenes with a very dark
backgrounds.
3D Multi-Sensor Fill-Flash is performed with all the
meters––Matrix, Centre-Weighted and Spot.
When the camera and the built-in flash are used with a non-D-
type AF Nikkor lens, Multi-Sensor Balanced Fill-Flash, which
offers the same flash output control system but without
Distance Information, is performed.
CENTRE-WEIGHTED/SPOT FILL-FLASH
If you are using a lens without CPU (a lens other than AF Nikkor
and AI-P-Nikkor), in automatic exposure mode, Centre-
Weighted Fill-Flash with Centre-Weighted Metering and Spot
Fill-Flash with Spot Metering are performed as Automatic
Balanced Fill-Flash. Flash output is properly compensated to
produce a natural fill-flash effect.
STANDARD TTL FLASH
In Manual exposure mode, standard TTL Flash will be
performed, regardless of metering system and lens in use. To
cancel Monitor Pre-flashes, perform Standard TTL Flash by
setting exposure mode to Manual.

Using 3D Multi-Sensor Balanced Fill-Flash with
two subjects at greatly different distances.
If you first focus on one subject and then, with the focus
locked, recompose the shot on another subject, it may
result in an incorrect exposure. This is because the
focusing distance for the first subject only was sent to
the camera’s computer. To correct this, refocus on the
second subject or cancel the 3D Multi-Sensor Balanced
Fill-Flash to activate the Standard TTL Flash.
