My Nikon SB-800 doesn't seem to sync with my D300s. I have tried everything inc resetting the flash, I've been through all the menu's on the camera & the flash. I have also updated the camera firmware too. The D300's built in flash is fine, the problem only occurs when I attach the SB-800 to the camera. It looks as though the flash isn't firing at the same time the shutter is opening. I have tried longer exposures too as well as 'rear' flash and 'slow' .
It was working fine but the half way through last night's photos at a wedding it started to play up.
Has anyone got any ideas! thanks Warren
I have an SB-900 which I use with the D700. Sometimes there is a connectivity problem in that the flash doesn't seem to sit tight enough in the hotshoe for all the connectors to meet up. When this happens the flash doesn't fire and the info in the viewfinder goes blank and shutter won't fire. Pushing down slightly on the flashgun reconnects it. It is annoying, not found a solution yet. Don't know if this is the same problem you are having? For heavy flashguns the little locking lever really isn't sufficient. Need a more heavyweight screw down system like some of the older ones.
This is a well know problem with the SB-800 and D300 and is due to a contact issue between the shoe and the flash. The camera is slightly mis-designed in this area! I just hope your not having your pants pulled down with the repair as my fix is to slide some tin foil between the camera shoe and the flash!
