Multi-Sensor Balanced Fill-flash

This mode automatically controls flash output so as to keep both

subject and background perfectly exposed.

The SB-27 fires a series of nearly invisible preflashes or Monitor

Preflash, which are detected by the TTL multi-sensor (5-segment

sensor) in Group I cameras to help determine the best exposure

for both subject and background. This method is most effective in

scenes that include: (1) a mirror, white wall or other highly

reflective surface, and (2) a subject positioned against an “infinity”

background (empty sky, clouds, etc.) With non-D-type AF Nikkor

lenses, Multi-Sensor Balanced Fill-Flash will operate.

(Applicable to F5, F100, F90X/N90s, F90-Series/N90, F80-Series/N80-Series,

F70-Series/N70)

Multiple flash operation

Flash operation using more than one speedlight to eliminate harsh

shadows or to illuminate a distant background.

(Applicable to all camera groups)

Non-TTL auto flash

The light output is automatically controlled to match the flash-to-

subject distance measured by the Speedlight’s light sensor.

(Applicable to all camera groups)

Programmed TTL Auto Flash

Simply set the lens to its minimum aperture (highest f-number),

and the camera automatically controls the aperture according to

the ISO film speed.

(Applicable to F-501/N2020, F-401s/N4004s, F-401/N4004, F-301/N2000)

Rear-curtain sync flash

In this case, the flash fires at a later stage of the exposure, just

before the rear shutter curtain starts to close. This is effective for

highlighting subject movement at a slow shutter speed. This

method turns available light into a stream of light that follows the

flash-illuminated moving subject. In front-curtain sync flash,

available light turns into a stream of unnatural light that appears

before the flash-illuminated moving subject.

(Applicable to F5, F100, F90X/N90s, F90-Series/N90, F80-Series/N80-Series,

F70-Series/N70, F65-Series/N65-Series, F-601/N6006, F-601M/ N6000,

Pronea 600i/6i)
