Nikon SB-5000 AF Speedlight.
Nikon has reimagined both on- and off-camera lighting with the SB-5000 AF Speedlight, which brings revolutionary radio control to the Creative Lighting System with Advanced Wireless Lighting and comes equipped with a world's first shoe-mounted flash cooling system that enables up to 100 consecutive full-power flashes. These features alone are enough to put it at the top of the speedlight heap, but the SB-5000 doesn't rest and provides a powerful guide number of 113' at ISO 100 and 35mm while also shrinking in overall size compared to its predecessors.
