I have a Nikon D800E and a flash commander SU800. I would like to use the SU800 to fire some Westcott studio stobes. The stobes in fact do fire with the shutter button on the D800, however the resulting picture is black. It seems like the SU800 is firing too soon, or with some sort of preflash causing the strobes to fire early. The shutter has not had time to even begin its journey. For the record, a simple wire coming from the camera output next to the 10-pin connector connected to the corresponding jack on the strobe will cause the strobe to fire correctly and produce a good picture.
Anybody have any thoughts on that problem, or tried it?
