Have not had an external flash before and have no further lightning habit. Using it on a Nikon D200. Have had it for two weeks and is so far very satisfied. In iTTL-mode, it is very easy to use. Pictures are great, thought that the running time would be longer.

Now just looking at the above comparison of specs, what we on the surface is that the Nikon SB-900, unexpectedly, leads in many areas of performance and functionality. However, there are some important distinctions between these three flashes in the Nikon speedlight lineup.
