The Nikon SB-5000 is a flasher with built-in cooling and radio control with a range of up to 30 meters. Thanks to this advanced radio system, the SB-5000 has the same performance even if your line of sight is blocked or if an optical signal weakens due to bright sunlight. This development and other advanced features give this wireless flasher unprecedented control. The SB-5000 is an i-DDL Speedlight flasher compatible with the Nikon FX or DX SLR cameras.
