Nikon Corporation is pleased to announce the introduction of the Nikon SB-50DX Speedlight.

The new Nikon SB-50DX has a variety of flash functions in its compact body, and is designed especially for users of Nikon SLRs with built-in Speedlights.

The SB-50DX can fire flash light with a camera's built-in Speedlight for greater flash power. It also offers various features that are not possible with built-in Speedlights, such as bounce flash capability, close-up shooting, built-in wide flash adaptor for 14mm wideangle coverage, TTL wireless slave flash, and an infrared remote commander.
