The Nikon Speedlight SB-11 is a very large flash. It is big, and it is of a size which will make you say "this flash is not small." Others will look at the flash and say "what are you going to do with a flash that big?" Well, what are you going to do? It's nobody's business but your own so you can keep it a secret. It uses 8 AA batteries and includes a bracket to attach the flash to your camera. Actually, it's more like attaching your camera to the flash, due to the goliath proportions of the flash. The flash connects with a PC sync cable, which is included. Cosmetic condition is vast but good, with minor wear; minor cleaned-up corrosion on a few battery contacts which will not affect function.
