Nikon SB-900 TTL AF Shoe Mount Speedlight, Guide Number 132 - Demo Model

SB-900 Speedlight provides Nikon digital SLR photographers with a flash capable of a wide zoom range, increased versatility, faster recycling time, and a wealth of intelligent features to enhance the already vast functionality of the Nikon Creative Lighting System (CLS)

The SB-900 offers a zoom range coverage from 17 to 200mm, three light patterns; "Center-weighted" provides the highest guide number "Standard" provides a familiar pattern, similar to the SB-800 and "Even" which delivers the most consistent edge-to-edge coverage, and an advanced wireless i-TTL capabilities allowing the utilization of multiple Speedlights

. The SB-900's innovative design has the xenon flash tube and reflector system moving independently - allowing for a wider zoom range from an extreme wide angle of 17mm (FX) to the telephoto setting which reaches 200mm without the aid of accessories or as wide as 12mm in DX mode with the built-in wide-angle panel engaged.

The SB-900 offers a quick recycle time of 4.0 seconds (at full power) with four Alkaline AA batteries which drops to a mere 2.3 seconds (at full power) while using four rechargeable NiMH batteries about 25 percent faster than the SB-800 with its fifth battery attachment.

Controls for setting the wireless Master and Remote have been relocated to the outside of the unit for easier access and frequently used functions are easily adjusted with a new Rotary Select Dial. A larger LCD screen is easy to read, even in direct sunlight, and photographers can assign "My Menu" hotkeys for quicker access to commonly used functions.

For the first time, Nikon SB-900 Speedlight users will have the ability to take advantage of future performance advancements.The user will be able to download the firmware onto a flash media card and upload it to the flash unit through select digital SLR cameras.*

The SB-900 Speedlight is Nikon's most intelligent Speedlight ever, created in response to the needs of today's digital photographic professionals. When using the included fluorescent or incandescent filters and adaptor, the flash automatically recognizes what filter is being used and automatically adjusts white balance accordingly on the latest Nikon D-SLRs.* Additionally, the SB-900 aids auto focus with a broader AF assist beam that covers a wide 20-105mm that is matched to all of the D3, D700 and D300's 51 focus points. The bounce and swivel capability of the SB-900 has been expanded to include: tilt up to 90 degrees, down minus 11 degrees, and a full 180-degree swivel left or right, allowing more creativity for on or off camera use, or as a remote Speedlight.
