Nikon SB-27 Multi-Sensor Balanced Fill-flash, Multiple flash operation, Non-TTL auto flash

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)
