About the SB-900
SB-900 features
Features of the SB-900
The SB-900 is a high-performance CLS-compatible Speedlight with a large guide
number of 34/48 (ISO 100/200, m) (111.5/157.5, ft.) (at the 35 mm zoom position
in Nikon FX format with standard illumination pattern, 20°C/68°F.)
Combined with a CLS-compatible camera, the SB-900 can easily perform various
types of flash operations, such as i-TTL auto flash and wireless multiple flash
(
k
D-39).
Three types of illumination patterns (standard, center-weighted and even) are
available to match different shooting preferences.
FX/DX selection enables the setting of the light distribution angle in accordance
with the camera’s image area between FX- and DX-formats, and provides
effective and high-quality lighting.
Power zoom function automatically adjusts the zoom position to match the lens
focal length from 17 mm to 200 mm (in FX format)/12 mm to 200 mm (in DX
format). When the built-in wide-flash adapter is used or the Nikon Diffusion
Dome is attached, the zoom position is automatically set to match a wideangle
lens with much shorter focal length.
Bounce flash (
k
D-26) or close-up flash photography can be easily performed
(
k
D-30).
Custom functions are provided to allow for various settings (
k
C-20).
Compatible cameras
The SB-900 has been optimized for use with CLS-compatible SLR cameras.
