3D Multi-Sensor Balanced Fill-Flash
3D Multi-Sensor Balanced Fill-Flash can be performed only with
a combination of F5 camera, D- or G-type Nikkor lens and
Nikon SB-50DX/SB-28/SB-28DX/SB-27/SB-26/SB-25 AF
Speedlight. In this flash mode, just after you depress the shutter
release button and before the shutter is activated, the
SB-50DX/SB-28/SB-28DX/ SB-27/SB-26/SB-25 will fire a
series of imperceptible pre-flashes (Monitor Pre-flashes) that are
detected by the F5’s TTL Multi Sensor, then analyzed for bright-
ness and contrast. Furthermore, it integrates Distance
Information from the D- or G-type Nikkor lens in use, with other
exposure control information, to automatically compensate the
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 a correct exposure even in difficult
situations, including scenes with a very reflective object such as
a mirror or a white wall, or scenes with a very dark background.
3D Multi-Sensor Balanced Fill-Flash can be performed with the
Matrix or Center-Weighted Metering.
Multi-Sensor Balanced Fill-Flash
When the F5 camera and SB-50DX/SB-28/SB-28DX/SB-27/
SB-26/SB-25 are used with a non-D/G-type Nikkor lens, Multi-
Sensor Balanced Fill-Flash, which offers the same flash output
control system but without Distance Information, is performed.
Multi-Sensor Balanced Fill-Flash can also be performed with the
SB-24 and other dedicated Speedlights that do not have the
Monitor Pre-flash feature.
Center-Weighted Fill-Flash
This feature can be used with all AF Nikkor lenses. Use Center-
Weighted Metering to determine the ambient exposure control
settings, and the F5’s TTL flash sensor will automatically control
the flash output for a balanced fill-flash effect. Experiment by
determining which brightness value you want to use for the
ambient exposure setting and which flash compensation setting
you want to use. This combination of features enables you to
maintain exceptional control over the system, yet allows the
system’s automation to work for you at the same time.
Standard TTL Flash
In standard TTL flash, automatic flash output level compensa-
tion is not available. This means that, even though the main
subject is correctly exposed, the background may not be.
With SB-50DX, SB-28/28DX, SB-27, SB-26, SB-25 or SB-24,
standard TTL flash offers manual selection of the flash output
level compensation instead of having the computer do it auto-
matically. So, with SB-50DX, SB-28/28DX, SB-27, SB-26, SB-
25 or SB-24, you can intentionally cancel Automatic Balanced
Fill-Flash by pressing the Speedlight’s M button (or MODE
button with the SB-50DX/SB-28/28DX).
