The SB-900 i-TTL Speedlight leads the Nikon Creative Lighting System by delivering the portability, power, and versatility to support any photographer's creative lighting imagination. The SB-900 works as a wireless standalone flash, or you can use it as a commander or wireless remote light source. In commander mode, the SB-900 controls up to three remote Speedlight groups and an unlimited number of compatible Speedlights, with four wireless channel options helping you manage wireless conflicts in multiple photographer environments. The flash also offers streamlined controls and menus, including a rotary select dial that sets key flash functions quickly, along with a prominent master and remote control switch to simplify wireless operation.
Photographers working on zoom photos will appreciate the SB-900's expanded auto power zoom coverage, which ranges from 17 to 200mm in the FX format to 12 to 200mm in the DX format. Photographers also have the choice of three light distribution patterns: standard (for general illumination), center-weighted (for portraits), and even (for groups or interiors). Finally, the SB-900 automatically identifies mounted color gel filters and adjusts the camera's auto white balance setting (available with select Nikon digital SLR cameras). Other details include automatic FX/DX format identification; user-friendly firmware updating; flash tube overheat protection; and a drip-proof mounting foot cover.
