Nikon has reimagined both on- and off-camera lighting with the Nikon SB-5000 AF Speedlight Flash, 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. Of course, 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. Along with this, 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 6 groups of flashes from up to 98' away, without requiring any line of sight. Also, the SB-5000 and the radio system are fully compatible with the existing optical triggering method of older units and can even be mixed and matched for maximum versatility. {Key Features} - Radio Control Advanced Wireless Lighting - Cooling System for 100 Consecutive Shots - Compatible with Nikon i-TTL - Guide Number: 113' at ISO 100 and 35mm - Zoom Range: 24-200mm (14mm with Panel) - Tilts from -7° to 90° - Rotates Left & Right 180° - Info Button for Quick Access to Settings - Recycle Time: 1.8-2.6 Seconds - Slow, High-Speed, 1st & 2nd Curtain Sync {Box Contents} - Nikon SB-5000 AF Speedlight - SW-15H Diffusion Dome for SB-5000 Speedlight - AS-22 Speedlight Stand - SZ-4FL Fluorescent Filter - SZ-4TN Incandescent Filter for SB-5000 AF Speedlight - SS-5000 Soft Case for SB-5000 AF Speedlight
