Nikon have added a powerful flashgun to their range of
SLR accessories. The new SB-50DX has a guide number of 26m/ISO100 and is
designed especially for users of Nikon SLRs with built-in flashguns.
The SB-50DX can fire flash light with a camera's integral Speedlight for greater flash power. It also offers various features that are not possible with built-in guns,such as bounce flash capability, close-up shooting, built-in wide flash adaptor for 14mm coverage, TTL wireless slave flash, and an infrared commander.
