Nikon - SB-800 Speedlight - KIT BUNDLE SAVINGS!

The SB-800 is an awesome flash, very powerful, nearly as much light as some studio monolights.  It includes an extra battery holder which makes absolutely no sense.  The flash takes 4 AA rechargeables and the extra holder has one more.  It is unbelievably inconvenient to charge one AA battery by itself so I don't use it.  I just have an extra set of 4AA rechargeables ready.

The SB-800 can be used on the shoe or remotely.  On the show I run TTL mode which is fantastic, the exposures are very good.  At a slow shutter speed (like 1/15) I can get a lot of ambient light in the picture and the flash doesn't overexpose the rest.
