Nikon SB-910 is Nikon's most sophisticated and powerful Creative Lighting System portable Speedlight designed for use on camera as well as for complete wireless control in the studio or on location. Nikon's flagship Speedlight for enthusiasts and professionals. Engineered for FX and DX-format D-SLRs and COOLPIX P7000 Series cameras, the Nikon SB-910 offers unparalleled lighting performance in the field and in the studio. Featuring Nikon's versatile i-TTL (intelligent through-the-lens) metering for on camera or wireless flash control, the Nikon SB910 can operate as a hot shoe mounted Speedlight, remote unit or wireless Commander. And with refined operability including illuminated buttons for use in low light and improved thermal cut out protection, the Nikon SB-910 is the perfect partner to your D-SLR. Real world simplicity with advanced automation. At the heart of the Nikon SB-910 is Nikon's i-TTL flash control which enables Nikon Speedlights to share critical exposure information with CLS compatible D-SLRs. All of the complex lighting calculations are computed for you instantly with consistently accurate results in just about any lighting situation. Using the SB-910 as a Commander or the in concert with the SU-800 Commander or D-SLR with built-in Commander operating as the Master controller, you can wirelessly manage and fire up to three groups of remotely positioned SB-910, SB-900, SB-700 and SB-R200 Speedlights. Additionally, each group can contain any number of Speedlights and any mix of these Speedlights. Nikon SB-910 can also be set as a Remote Speedlight for complete system integration and control. Seamless integration with Nikon's Creative Lighting System. The Nikon SB-910 Speedlight operates as a hot shoe mounted Speedlight, remote unit or wireless Commander (with up to four channel options) capable of controlling as many as three remotegroups (A,B and C) and an unlimited number of SB-910, SB-900, SB-700 or SB-R200 units. With a host of pro flash features including; precision i-TTL flash control, Manual with Power Ratio, three illumination patterns for specific shooting environments, wide zoom range from 17-200mm, and streamlined controls and menus it's no wonder that Nikon is the overwhelming choice when it comes to flash photography. Versatile flash for enthusiasts and professionals. Nikon SB-910 offers an improved interface, adding a dedicated Menu button and illuminated buttons for control inlow light. Additionally, hard type color correction filters are now used, providing durability and convenience when used with a camera set for Auto white balance. And when taking pictures in certain situations such as in rapid sequence, to prevent the flash tube from overheating, an improved thermal cut out protection has been adopte d that slows recycling instead of cutting off the flash.
