Nikon has reimagined both on- and off-camera lighting with the SB-5000 AF Speedlight 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. The SB-5000 AF Speedlight is fully compatible with Nikon's i-TTL automatic exposure system found in a majority of their cameras for fast, accurate operation. The radio control implemented in the SB-5000 requires a compatible DSLR using the WR-A10 Wireless Remote Adapter and WR-R10 Wireless Remote Controller in order to fully realize the power of the system.  This enables the camera and flash to wirelessly control up to six groups of flashes from up to 98' away, without requiring any line of sight. Designed for reliability as well as versatility, the innovative built-in cooling system of the SB-5000 is a first for shoe-mounted flashes.  It vents heat quickly and efficiently, allowing you to fire up to 100 consecutive full power flashes without issue. It also means that the flash can be made smaller without compromising performance. As a standard flash the SB-5000 will not disappoint, providing a wide-ranging zoom head of 24-200mm which can be extended down to 14mm with use of the built-in diffusion panel. The head will also tilt from -7 to +90° and rotate left and right 180° for complete bounce capabilities. Full sync mode support is available with slow, high-speed, 1st and 2nd curtain options. Commander Mode to set up optical wireless flashes in 3 groups and in one of 4 channels.  A PC terminal can be found on the SB-5000 for further triggering options and it comes with a stand, diffusion dome, fluorescent and incandescent filters, and a soft case.
