Official announcement:
http://www.nikon.com/news/2016/0106_sb_03.htmA high-output, multi-functional, high-end model that is the first Nikon Speedlight to be equipped with a radio control function
TOKYO - Nikon Corporation is pleased to announce the release of the SB-5000, the new high-end Nikon Speedlight.
The SB-5000 is the first Nikon Speedlight to be equipped with a radio-controlled Advanced Wireless Lighting function, and is also equipped with a cooling system that enables more than 100 continuous full-power flashes. When used with the Nikon D5 or D500 digital SLR cameras released at the same time as the SB-5000, the wireless multiple flash photography that professional and advanced amateur photographers often take on is even more flexible.
Primary features
Radio-controlled Advanced Wireless Lighting
The SB-5000 is the first Nikon Speedlight to be equipped with a radio-controlled Advanced Wireless Lighting function. Radio control makes wireless multiple flash photography easier in situations where conventional optical control is difficult, such as when remote flash units are positioned behind objects or at greater distances, or when ambient lighting is very bright (supports a communication range of up to approx. 30 m). A more flexible multi-flash system supports capture of even more creative photographic works with advanced wireless lighting.
*Supported by the D5 and D500 (as of January 6, 2016).
*Wireless Remote Controller WR-R10 and WR Adapter WR-A10 (both available separately) required. WR-R10 firmware must be updated to enable support for radio-controlled Advanced Wireless Lighting (see Nikon's website).
Equipped with a cooling system for significant increase in the number of continuous flashes
The SB-5000 is equipped with a new cooling system that cools the flash head. The cooling system has been significantly improved, keeping the flash panel from overheating and enabling more than 100 continuous flashes. As the cooling system keeps the Speedlight from overheating, professional and advanced amateur photographers can enjoy more comfortable and active flash photography.
Smaller with improved operation
Despite its smaller size, SB-5000 operation has been refined by assigning a number of functions to the rotary multi selector and OK button. Adoption of an button, which offers quick access to frequently used functions, also contributes to more efficient operation. What's more, when the SB-5000 is used with the D5 or D500, even more agile and flexible flash photography is possible.
