Gn rating The hefty maximum power rating of Gn 56/184 (ISO100, metres/feet) at 105mm zoom puts later Nikon flashguns like the SB-700, SB-900 and SB-910 in the shade.
Wireless remote Full master and slave functions are built in, for multi-flashgun lighting set-ups. The SB-800 can also be used off-camera, triggered from a pop-up flash, so long as a Commander mode is available.
Sync terminals There are two terminals built into the SB-800. One is for firing the flash off-camera via a cable, the other enables TTL flash with multiple cord-connected flashes.
