Nikon D300 - SU-800 Wireless Speedlight Commander Unit

Figure 12-17. SU-800 Wireless Speedlight Commander Unit
While not a Speedlight flash, I wanted to show you the Nikon
SU-800 Wireless Speedlight Commander Unit (see
Figure 12-17). This unit can be used when you need extra
range (up to 66 feet) or need to control more than two banks
of flash units—it can control three. It uses wireless infrared
signals to control the flash banks. It is mounted onto the
Accessory shoe of your camera, thereby precluding the use of
the built-in flash.
