A first for Nikon flash units, the latest firmware for the Nikon SB-900 Speedlight can be downloaded from Nikon's website to a memory card while the SB-900 is mounted on a D3, D3X or D700.
The SB-900 serves as the new core for the Nikon Creative Lighting System when used in combination with current Nikon digital SLRs, and it supports Advanced Wireless Lighting as a master or a remote Speedlight.
