CLS-Compatible Flash Units
The D3 can be used with the following CLS-compatible flash units:
the SB-800, SB-600, SB-400, SB-R200, and SU-800.
❚❚The SB-800, SB-600, SB-400, and SB-R200
The principal features of these flash units are listed below.
❚❚SU-800 Wireless Speedlight Commander
When mounted on a CLS-compatible camera, the SU-800 can be
used as a commander for remote SB-800, SB-600, or SB-R200 flash
units.
The SU-800 itself is not equipped with a flash.
A Guide Number
To calculate the range of the flash at full power, divide the Guide Number
by the aperture.
For example, at ISO 100 the SB-800 has a Guide Number
of 38 m or 125 ft.; its range at an aperture of f/5.6 is 38÷5.6 or about 6.8
meters (or in feet, 125÷5.6=23 ft. 7 in.).
For each twofold increase in ISO
sensitivity, multiply the Guide Number by the square root of two
(approximately 1.4).
