Nikon Speedlight SB-600 flash. Rotating and flexible head is durable and easy to work with QUICKLY. (Important for wedding/event photography!) Has excellent coverage to light up an entire room. Fairly easy controls for setting manual flash and zoom. Works with the Nikon Creative Lighting system to be used off-camera. I have two of these (~$275 each), a.) in case I need one on both of my cameras, b.) for lighting portraits and events off-camera, c.) and in case one fails :-/ !
