Nikon Introduces Speedlight SB-400

The SB-400 gives photographers the opportunity to enjoy brighter and more natural lighting for images taken using a flash. It is designed to suit entry-level digital SLR users yet it is also suitable for more experienced users. Those who have a camera within the D2 series will also benefit from the convenient portable flash unit. The SB-400 offers a guide number of 30 (ISO 200, m), and effortless bounce flash function and is controlled in i-TTL and the D40’s M (manual) mode.


Due to its compatibility with Nikon’s Creative Lighting System, entry level users are able to experience a sophisticated wireless lighting system that is easy to use. Its flash head can be tilted in 4 steps, horizontal, 60, 75 and 90 degrees, and has a flash shooting distance range from 0.6m to 20m (depending on the ISO setting). Slow Sync, Red-eye Reduction and other flash modes can also be set on the camera body.
