This Nikon SB-900 Flash w/ Bolt Power Pack & Cable Kit from B&H Photo delivers a complete top quality camera flash outfit for your Nikon camera. Nikon's flagship shoe-mount flash, the SB-900 has an automated zoom head that's been expanded to cover 17mm to 200mm lenses (in 35mm/FX format), and can cover this range in just 1.2 seconds. You can select from three light distribution patterns: Standard, Center-weighted, and Even, and the SB-900 will even automatically detect if it's connected to a DX or FX format camera, and adjust itself accordingly.
The Bolt Cyclone power pack can give you up to 400 full-power flashes, with a lightning quick recycle time of 1 second. The included charger will completely charge the pack in 2 hours on 100-240VAC. The CKE cable that's included in this kit is a dedicated cable for the SB-900 flash, so you're immediately ready to start shooting.
