Query: Excellent value.

The SB-400 complements my Nikon D40 and gets great results. Nikon digital cameras automatically control the power output of the SB-400 for great results every time. I bought this speedlight for the ability to use bounce lighting for great photos. The speedlight can be tilted up in various degrees to get the results you want. This product fills my needs and the price is right.
