Selling my Nikon SB-600 flashgun. This is an excellent condition and tested on my Nikon D90. The only minor issue is that the flash randomly discharges when it reaches full charge. This is a common issue with this gun and I believe it is due to a capacitor not holding the charge. When on the camera the flash works fine with full functionality and stops any discharge when it goes into standby when not in use on the camera. Selling cheaper as a result. Please see my other Nikon listings as having a final clear out of unused Nikon gear. Thanks for looking.
