The built-in Speedlight offers an angle of coverage of 28mm tens with
a guide number of 12 (ISO 100, m).
Using a D-type Nikkor lens enables use of 3D Multi-Sensor Balanced
Fill-Flash. (For details, see page 78.)
Be sure to remove (or store) the lens hood before flash shooting.
Some lenses have limitations using the built-in Speedlight and may
cause vignetting. (For details, see page 84.)
• Normal Front-Curtain Sync flash mode is introduced in this section. Flash
with Red-Eye Reduction, which reduces the "red-eye" effect with a
person or animal, and Slow Sync flash, which brings out the background
details, are also available. For details, see page 80.
• With dark subjects, the camera's AF-Assist Illuminator is automatically
activated to guide autofocus. See page 43 for details.
3D Multi-Sensor Balanced Fill-Flash
When a D-type Nikkor lens is attached, it integrates Distance
Information from the lens with other exposure control information,
automatically compensating the flash output level so that flash output
and ambient light are balanced (page 78).
About Metering System and Exposure
Metering systems and exposure are important factors for taking
pictures. Knowing the characteristics of each factor helps you
widen your photographic expression.
•Metering System
As the proper combination of shutter speed and aperture for correct
exposure is determined according to subject brightness and film
sensitivity, measuring subject brightness is very important.
In general, brightness inside the viewfinder is not uniform. The
F80/F80D/F80S provides three metering systems: Matrix Metering,
Centre-Weighted Metering and Spot Metering. With Matrix Metering,
scene brightness data is detected by the 10-segment Matrix sensor. With
Centre-Weighted Metering, most of the meter's sensitivity is
concentrated on the 12mm-diameter centre circle in the viewfinder. Spot
Metering sensitivity is concentrated in a small, selected focus area from
five available focus areas. Using D-type Nikkor lenses, the F80/F80D/
F80S camera performs 3D Matrix Metering by adding distance
information to determine correct exposure. See page 48.
