When i take a phot with the build-in flash on D5000 it's okay everytime. But when i connect the SB-900 Speedlite flash, then it's only the first photo who is well illuminated, the rest will be very underexposed.
This is really a riddle for me what's wrong?
I have reset both camera and flash, nothing helps. Does somebody have a good suggestion?
Welcome to Nikonians! Does the SB-900 fit snugly in the cameras hotshoe or is there excessive play? Is the Speedlight locked into the cameras hotshoe? Did you try cleaning the electrical contacts on both the Camera and the Speedlight? Good Luck and Enjoy your Nikons!
