Have to remember this is all about the flash itself. If on Auto mode it has nothing to do with the camera all exposure values are by what you set on the flash and what the flash reads through it's sensors. It sends out the flash reads the subject and determines the amount. The only thing the camera has to do with any of it is actually firing the flash. Now obviously you have to set the flash and camera to match output in F stops and ISO as well. Now I am not sure the Nikon can actually fire have not tried it myself but my guess it will. My Metz 54 works like a charm on the GF1. Just need to be in manual mode on the camera and set F stop, shutter and ISO to match each other.
