Tokyo, Japan, June 15, 1999 — Nikon Corporation proudly announces the
introduction of the Nikon SB-28DX Speedlight.
In addition to
offering all the features of Nikon’s SB-28 Speedlight, this new flash unit
enables TTL flash control with the new Nikon D1 professional digital SLR
camera.
The SB-28DX unit offers most of the same advanced flash
control features as the SB-28 Speedlight and is compatible with current
Nikon SLR cameras.
The SB-28DX features 3D Multi-Sensor
Balanced Fill-Flash for D1, designed specifically for Nikon’s D1
digital SLR. It also offers AA (Auto Aperture) Flash capability with the
Nikon D1.
SB-28DX Features
Features designed specifically for the Nikon D1 digital SLR
camera
3D Multi-Sensor Balanced Fill-Flash for D1
•
The Speedlight sets off a series of Monitor Pre-flashes before the main
flash fires. The pre-flashes are detected by each of the five segments of
the D1’s TTL Multi Sensor. As a result, the main subject is properly
illuminated by flash, and the background comes out looking natural for a
well-balanced, superbly lit shot.
• Since the D1 uses a CCD instead
of film, TTL flash control has been redesigned to ensure the same
high-quality results offered by the 3D Multi-Sensor Balanced Fill-Flash
feature of current Nikon SLRs.
• The D1 employs a shutter blade
located in front of the CCD. This allows TTL monitoring of the pre-flashes
just before exposure and even after the reflex mirror goes up.
• A
range of data is transmitted to the SB-28DX automatically (when using a
CPU lens*). Transmitted data includes: sensitivity, aperture value, focal
length of the lens in use, and exposure compensation value.
• The
following functions are available depending on the type of lens in use
and/or camera settings:
3D Multi-Sensor Balanced Fill-Flash for D1
(with D-type AF Nikkors)
In addition determining the results of
Monitor Pre-flashes, Distance Information is also evaluated for more
precise TTL balanced fill-flash control.
Multi-Sensor Balanced
Fill-Flash for D1 (with non-D-type AF Nikkors)
Delivers a balanced
exposure of the main subject and background according to the results of
the Monitor Pre-flashes (for main subject exposure) and Matrix Metering
(for background exposure).
Centre-Weighted Fill-Flash for D1
(AI-type Nikkors)
Delivers a balanced exposure of the main subject
and background according to the results of the Monitor Pre-flashes (for
the main subject exposure) and Centre-Weighted Metering (for the
background exposure).
Standard TTL Flash for D1 (All compatible
lenses)
The Centre-Weighted Meter, instead of the TTL Multi Sensor,
detects monitor Pre-
flashes. Flash exposure is thus controlled without
balancing the foreground and
background exposure.
• Flash
output level compensation from -3 to +1 EV in 1/3 EV steps. The
compensation value can be confirmed via the rear LCD panel. Since the D1
shows the results immediately after shutter release, photographers can
easily obtain the image that they want. (Can be used simultaneously with
the camera body’s flash output level compensation feature.)
AA
(Auto Aperture) Flash
• AA (Auto Aperture) Flash is possible
when connected to the Nikon D1 with a CPU lens* attached.
• A
range of data is transmitted to the SB-28DX automatically (when using a
CPU lens*). Transmitted data includes sensitivity, aperture value, focal
length of the lens in use and exposure compensation value. The SB-28DX
uses this data to control flash output via the light sensor on the front
of the unit.
• Non-TTL Auto Flash operation is automatically
selected when using non-CPU lenses.
• Flash output level
compensation is possible from -3 to +1 EV in 1/3 EV steps. The
compensation value can be confirmed via the rear LCD panel. (Can be used
simultaneously with the camera body’s flash output level compensation
feature.)
*CPU lenses refer to those AF Nikkor, D-type Nikkor, or
AI-P Nikkor lenses that feature a built-in microcomputer and CPU contacts.
