Nikon SB-910 AF Speedlight

Engineered for FX and DX-format D-SLRs and COOLPIX P7000 Series cameras, the 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 SB-910 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 SB-910 is the perfect partner to your D-SLR.

The 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 remote groups (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 menusit's no wonder that Nikon is the overwhelming choice when it comes to flash photography.

At the heart of the 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. SB-910 can also be set as a Remote Speedlight for complete system integration and control.

SB-910 offers an improved interface, adding a dedicated Menu button and illuminated buttons for control in low 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 adopted that slows recycling instead of cutting off the flash.
