In several weeks of shooting with the SB-900, we found its added bulk easily manageable. More important, its revised controls and overall handling are great improvements over the SB-800. The head now swivels 180 degrees in each direction for easier bouncing. The larger LCD panel displays far more info (some might say too much). The new central Selector dial is much sleeker and easier to operate than the relatively clunky and toy-like rocker switch on the SB-800. And now there are eight controls on the flash body (up from five), creating swifter operation and less reliance on buried menus, especially when going wireless.
