I doubt the connector is the problem. Install the flash/camera combo on a tripod, select a static subject, and expose a series of 4 shots with 200, 400, 800 and 1600 ISO. I don't see why the exposures shouldn't be identical. In real live with my D creates a series of underexposed, correctly exposed, over exposed and horribly overexposed depending on ISO setting. If I forget to use ISO 400 during flash use I'm in trouble.
