Product Overview
Nikon SB-900 Speedlight Flash
Advanced, high-performance Speedlight for Nikon digital SLR cameras
Key Features
- Multi-step auto zoom covers wide 17-200mm zoom range (24-105mm：SB-800)
- Three illumination patterns (standard, center-weighted and even) are available to match each shooting environment
- Automatically detects Nikon FX and Nikon DX formats and selects suitable light distribution
- Improved booster circuit for high-speed recycle time: Recycle time using four AA-size batteries is almost equal to the SB-800 with five AA-size batteries
- New AF-Assist illumination covers a wide 20-105 mm focal range compatible with the new Multi-CAM3500 FX/DX AF sensor
- Firmware update via Nikon D3 and D700 is possible (world's first*)
- Thermal Cut-out function limits the number of flashes to avoid deterioration of light emitting parts caused by continuous flash firing
- Automatically detects color filters (fluorescent or incandescent), enabling camera to control color temperature according to filter information from SB-900
- Optional Water Guard WG-AS1 (for D3), WG-AS2 (for D300), and WG-AS3 (for D700) is useful for protecting the camera's hot shoe contact when the SB-900 is mounted on these Nikon digital SLR cameras
