Creative Lighting System: The SB-400 features a new
Nikon Speedlight system, called Creative Lighting System (CLS). This system
offers additional flash shooting possibilities with digital cameras by taking
advantage of a camera's digital communication capabilities. CLS is available
only when the SB-400 is used with compatible Nikon cameras.
Compatibility: The SB-400 is
currently compatible with the following point-and-shoot and digital SLR Nikon cameras
(as of 12/30/2011).
- D-Series: 3, 3S, 3X, 300, 300S, 3000, 3100, 40, 5000, 5100, 60,
700, 7000, 90
- Coolpix Series: P5000, P5100, P6000, P7100
Note: List subject to change as newer model cameras are released.
Speedlight incorporates a microcomputer to control flash operations.
i-TTL Flash Operation: This is a new TTL
auto flash operation in
the Creative Lighting System. Monitor Preflashes are fired at all times. The
subject is correctly exposed by the light from the flash lighting and the
exposure is less affected by the ambient light than in the conventional TTL
Flash Modes: The SB-400's
available flash modes vary, depending on the cameras and lenses in use or the
camera's exposure mode. The following flash modes are available.
- Slow-Sync Flash: In
Slow-Sync Flash mode the flash is controlled at a slow shutter speed to
obtain the correct exposure for both the main subject and background in
low-light situations or at night.
- Red-Eye Reduction: Red-Eye
Reduction prevents the center of your subject's eyes from appearing red in
color pictures. The SB-400 fires three flashes at reduced output just before
the picture is taken.
- Red-Eye Reduction with
Slow-Sync Flash: In this mode, red-eye reduction is combine with the
- Rear-Curtain Sync:
Rear-Curtain Flash Sync creates a picture in which the blur or a moving
subject appears behind the subject and not in front.
- FV (Flash Value) Lock: FV
is the amount of flash exposure for the subject. Using FV Lock you can lock
in the appropriate flash exposure for the main subject.
- Exposure Compensation and
Flash output Level Compensation: Exposure compensation allows you to
take well-balanced pictures by intentionally modifying the flash exposure.
This is useful when a subject of extremely high or low reflectivity is
included in the scene or when you want to create flash photographs to match
your creative preferences.
- Manual Mode: Manual flash
operation is possible with only the Nikon D40 series.
Note: Each mode should
be set on the camera body, since it cannot be set through the SB-400.
Bounce Flash: With the SB-400
mounted on your camera's hot shoe, you can tilt the flash head in four steps
(horizontal, 60-degrees, 75-degrees or 90-degrees) to bounce the light off the
ceiling or other surfaces. This technique offers the following advantages -
eliminates red eye, creates soft shadows and prevents hair or clothing from
appearing to sheen .
Ready Light: The Speedlight
features a rear-mounted LED that lights up when the SB-400 is recharge and ready
to fire. The Ready Light will blink to indicate insufficient light, insufficient
battery power, incompatibility of camera with the SB-400 or overheating.
Power Source: The Speedlight
can operate off of two of the following AA-type penlight batteries (1.5V or
lower) - Alkaline manganese (1.5V), Lithium (1.5V), Oxyride (1.5V), Ni-MH
(rechargeable 1.2V). When the battery power becomes low the Ready-light blinks
twice in a second for approximately 40 seconds advising you to replace or
recharge your batteries.
Standby Function: If the SB-400 and camera are not
being used, the standby function will automatically activate after 40 seconds,
switching the SB-400 to standby mode to conserve battery power.
Mounting: The Speedlight mounts
to the accessory shoe of your compatible Nikon camera via the unit's mounting
foot lever lock which provides secure attachments to prevent accidental
